<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> </head> <body> <h2>Wolfskers zaden (Atropa belladonna)</h2> <h2>Prijs voor pakket met 5 zaden.</h2> Atropa Belladonna, of duivelskers, wordt al meer dan twee millennia gebruikt als medicijn, cosmetica, gif en heksenplant. Belladonna is een meerjarige, gezaaide, vertakte plant die tot 1,5 meter hoog kan worden, met bladeren van 12-13 cm lang en een paarse stengel. Het sterft in de winter en loopt weer uit in het voorjaar. Eeuwenlang hebben heksen het gebruikt in formules, Venetiaanse vrouwen in het algemeen, en in het bijzonder "nachtdames" voor het verwijden van de ogen, en het wordt momenteel gebruikt als remedie tegen reisziekte, IBS en andere darmaandoeningen. Belladonna werd ook gebruikt om hele legers te vergiftigen in de oorlog. Er wordt gezegd dat Satan persoonlijk voor deze plant en zijn kleine "duivelskersen" zorgde. Bevat psychotrope / giftige / levensreddende alkaloïden, waaronder atropine. Deze plant is een medicijn, een hallucinogeen en een gif. De dood kan (en gebeurt) door slecht geïnformeerde mensen, bijvoorbeeld door te veel rijpe bessen in taarten te eten, dus doe dat niet. De bessen zijn heerlijk (ik heb ze zelf opgegeten en ze zijn best lekker). Dit is een plant die het hoofdbestanddeel is van de geheime formule-drank "Flying Formula" die heksen al eeuwenlang gebruiken. Dit kruid kan je echt het gevoel geven dat je ziel op reis is, maar te veel consumeren kan fataal zijn. Het kan ook worden gebruikt als tegengif voor gasvergiftiging. <h3>Cultuur</h3> Het kan worden vermeerderd door zaden of stekken te zaaien, hoewel het gebruik van zaden meer wordt aanbevolen. De zaden moeten een paar uur voor het zaaien in heet water worden gezet. Ze hebben tijd nodig om te ontkiemen en ze hebben een hoge luchtvochtigheid en warmte nodig, en met behoud van alle noodzakelijke omstandigheden is de ontkieming niet geweldig. Planten zullen het compostsubstraat met mest en een vochtige, schaduwrijke omgeving waarderen. Nitraten en ammoniakzouten zijn de beste meststof om de hoeveelheid alkaloïden te verdubbelen. <h3>WIKIPEDIA:</h3> Wolfskers (Atropa belladonna) (ook: belladonna of slaapbes[1]) is een vaste plant uit de nachtschadefamilie (Solanaceae). De plant is zeer giftig. Wolfskers komt van nature voor in Europa, Noord-Afrika en West-Azië en is van daaruit verspreid over de hele wereld. In Nederland is de soort zeldzaam en voornamelijk in Zuid-Limburg en Gelderland te vinden, maar hij komt ook voor in parken in de rest van Nederland. Deze plant is in Nederland wettelijk beschermd sinds 1 januari 2017 door de Wet Natuurbescherming. In België is de soort zeldzaam in de Ardennen en nog zeldzamer elders. De standplaats is op beschaduwde plekken, vooral aan de rand van het bos. <h2>Werkzame stoffen</h2> De hele plant bevat giftige alkaloïden. Bijzonder gevaarlijk zijn de bessen, die de uiterst giftige stof atropine bevatten. Het eten van drie bessen kan dodelijk zijn voor een kind. Voor een volwassene zijn tien tot twaalf bessen vaak fataal. De plant kan tot 1 m hoog worden. Ook de bladeren en wortels zijn zeer rijk aan deze alkaloïden. Verder bevat de plant hyoscyamine, scopolamine, pyridine en choline. <h2>Gebruik</h2> De soortaanduiding bella-donna is Italiaans en betekent 'mooie vrouw'. Vrouwen druppelden tijdens de Renaissance namelijk het atropine bevattende sap uit de plant in hun ogen om de pupillen te verwijden en ze donkerder en glanzender te maken. Dat ze daardoor ook slechter zagen werd voor lief genomen. Ook tegenwoordig gebruiken oogartsen de pupilverwijdende eigenschap van atropine nog steeds bij oogonderzoek. De hoeveelheid atropine die ze gebruiken is wel miniem. De botanische naam Atropa is afgeleid van Atropos, de naam van een van de drie schikgodinnen uit de Griekse mythologie. Het Oudgriekse woord 'atropos' betekent 'onafwendbaar'. Al in de oudheid werd de plant gebruikt. In de 19e eeuw werden extracten van de wolfskers gebruikt voor de behandeling van geelzucht, roodvonk, kinkhoest, zenuwziektes en epilepsie. In de middeleeuwen werd de plant gebruikt in levenselixers en beschouwd als heksenkruid waarvan heksen heksenzalf maakten. Bij matig inwendig gebruik kunnen er waanvoorstellingen en roestoestanden optreden. </body> </html>

Sint-janskruid zaden...

€ 1,95 SKU: MHS 45

Seeds Gallery Com,

<h2>Sint-janskruid zaden (Hypericum perforatum)</h2> <h2>Prijs voor een pakket van 1000 (0.1g) zaden.</h2> Het sint-janskruid (Hypericum perforatum) is een plant uit de hertshooifamilie (Hypericaceae). De vaste plant komt van nature oorspronkelijk voor in Europa, maar is van daaruit verder verspreid. Het kruid bloeit rond het Sint-Jansfeest op 24 juni, de tijd dat de zon op zijn hoogst staat, met gele bloemen die dan ook worden geoogst. De soort is al lang in gebruik als geneeskrachtig kruid en is als plantaardig antidepressivum verkrijgbaar. <h2>Beschrijving</h2> De plant wordt 20-85 cm hoog en heeft een ronde stengel met tot twee smalle lijsten. De kale, elliptisch tot eironde, gaafrandige, 1,5-3 cm lange bladeren hebben talrijke doorzichtige punten en een stompe bladvoet. De doorzichtige puntjes zijn gevuld met etherische olie. Sint-janskruid bloeit van juni tot september met gele bloemen. De kroonbladen zijn 1-1,6 cm lang. De kelkbladen zijn lancetvormig, spits en gaafrandig. De kroonbladen hebben weinig zwarte punten. De bloeiwijze is een tuil. De vrucht is een doosvrucht met, uitsluitend lange, klierstrepen (vittae). De plant komt voor op droge, grazige, voedselrijke plaatsen langs wegen, spoorwegen en struikgewas. <h3>Medisch gebruik</h3> Verschillende stoffen in sint-janskruid kunnen verantwoordelijk zijn voor de aan fytotherapeutische bereidingen van deze plant toegeschreven antidepressieve effecten. De hypericinen worden als de belangrijkste psychoactieve stoffen in de plant beschouwd, met name gaat het dan om hypericine, pseudohypericine en hyperforine. De meeste wetenschappelijke studies met Hypericum zijn uitgevoerd met een op 0,3% hypericine gestandaardiseerd extract, waaraan in de medische literatuur gerefereerd wordt als "LI 160". Een aantal hypericumproducten op de markt zijn hiernaar gemodelleerd en zijn eveneens gestandaardiseerd op 0,3% hypericine. De samenstelling van de verschillende sint-janskruidpreparaten varieert sterk. Sommige bevatten alleen hypericine, maar blijken toch werkzaam.[3] Ongeveer 20% van de hypericine wordt geabsorbeerd en komt na 1 à 2 uur in de bloedstroom. Hypericine heeft een relatief lange halfwaardetijd en blijft meer dan 24 uur in de bloedstroom. Sint-janskruid remt, net als de conventionele antidepressiva, de neuronale heropname van lichaamseigen serotonine, noradrenaline en dopamine. Tevens remt het de heropname van moleculen GABA en L-glutamaat.[4] Een studie uitgevoerd bij mensen met een zware depressie liet geen effect zien van sint-janskruid.[5] Bij lichte tot matige depressies is er wel bewijs voor de werkzaamheid.[6][7] Diverse kleinere studies wijzen erop dat sint-janskruid bij de behandeling van lichte tot matige depressie effectiever is dan een placebo en net zo effectief als tricyclische antidepressiva. Deze conclusie wordt ondersteund door verschillende meta-analyses en een Cochrane review.[8] In 2007 is een preparaat op basis van sint-janskruid door het Nederlandse College ter Beoordeling van Geneesmiddelen (CBG) geregistreerd als medicament tegen een milde of matige depressie.[9] Volgens het CBG heeft de aanvrager de werking van het product voldoende aangetoond. Sint-janskruid wordt ook wel gebruikt als middel tegen stress en slapeloosheid. Bij slapeloosheid die niet het gevolg is van een depressie kan het echter averechts werken. Sint-jansolie vervaardigd uit het kruid wordt gebruikt bij brandwonden en zonnebrand. <h3>Bijwerkingen</h3> Sint-janskruidpreparaten worden over het algemeen goed verdragen. Mogelijke bijwerkingen: <ul> <li>Maag-darmklachten</li> <li>Huidveranderingen (onder andere verkleuring)</li> <li>Moeheid</li> <li>Rusteloosheid</li> <li>Duizeligheid</li> <li>Hoofdpijn</li> <li>Slapeloosheid</li> <li>Droge mond</li> <li>Fototoxisch effect. Onder invloed van UV-straling van de zonnebank of zonlicht kan het huiduitslag en roodheid veroorzaken.</li> <li>Psychose (zeldzaam), vooral bij mensen met een bipolaire stoornis en toename van angst[10]</li> </ul> In het Nederlands Tijdschrift voor Geneeskunde is een casus gemeld van een patiënt met zelfmoordgedachten en agressiviteit die mogelijk verband hielden met het gebruik van sint-janskruid.[11] <h4>Interacties met geneesmiddelen</h4> Sint-janskruid kan de werking van geneesmiddelen nadelig beïnvloeden. Het versterkt de werking van het lever-enzymsysteem cytochroom P450,[12][13] waardoor een aantal geneesmiddelen sneller wordt afgebroken en daardoor een geringere werking heeft. Zo kan het gebruik van sint-janskruid onder andere de werking van de anticonceptiepil verminderen.[14] Tevens wordt de activiteit van het transporteiwit P-glycoproteïne verhoogd met eenzelfde effect. Waargenomen is dat gezondheidsproducten met sint-janskruid de werking van de volgende geneesmiddelen kunnen verminderen:[15] <ul> <li>hormonale anticonceptiva;</li> <li>antistollingsmiddelen van het coumarinetypetype, zoals acenocoumarol (onder andere Sintrom) en fenprocoumon (onder andere Marcoumar);</li> <li>anti-epileptica: fenobarbital en fenytoïne;</li> <li>luchtwegverwijders: theofylline;</li> <li>hartglycosiden: digoxine;</li> <li>hiv-remmers: indinavir;</li> <li>maagzuurremmer: omeprazol;[16][17]</li> <li>immuunsysteemremmers: ciclosporine.</li> </ul> Sint-janskruid kan de werking van antidepressiva beïnvloeden. Dit geldt ook indien een tricyclisch antidepressivum, zoals amitriptyline, bij neuropathie wordt gebruikt. Producten waarin Sint-janskruid is verwerkt verhogen de hoeveelheid serotonine in de hersenen. In combinatie met een MAO-remmer, een SSRI of clomipramine bestaat hierdoor kans op het ontstaan van het serotoninesyndroom.[18] Gelijktijdig gebruik van sint-janskruid en een antidepressivum wordt daarom afgeraden. Om deze reden is het sinds november 2001 verplicht om op de verpakking of in de bijsluiter van producten die sint-janskruid bevatten een tekst te vermelden waarin gewaarschuwd wordt voor de effecten op medicatie. <h3>Medisch gebruik in de oudheid</h3> In de oudheid werd sint-janskruid gebruikt bij brandwonden en andere wonden.[19] Hippocrates en Paracelsus († 1541) hebben dit gebruik beschreven. Sint-janskruid is in alle Europese culturen een belangrijke plant, er zijn vele legenden aan de plant verbonden; in een aantal gevallen was het zelfs een cultusplant. Het kruid is genoemd naar Sint-Jan, omdat het hoogtepunt van de bloei op de feestdag van Sint-Jan valt (24 juni); ook is St. Jan de heilige van het Licht, zijn feest valt in de periode van het oude Midzomerfeest, waaraan de Sint-Jansvuren nog herinneren. De rode olie die de plant bevat heeft tot veel legendevorming geleid: bij de oude Germanen zou het het bloed zijn geweest van Baldr, de Germaanse god van de Natuur, de Zomer en het Licht, maar ook het bloed van oppergod Wodan nadat hij door een everzwijn was verwond. Aan het kruid werden allerlei magische krachten toegedicht, bijvoorbeeld bond men het op daken om te beschermen tegen onweer. Ook waren er vruchtbaarheidsrituelen verbonden aan het kruid, bijvoorbeeld: een vrouw die graag kinderen wilde, moest op Midzomernacht naakt het kruid plukken. <h3>Sint-janskruid als afweermiddel</h3> De bijnaam "jaag den duvel" geeft aan dat sint-janskruid volgens overleveringen vroeger ook wel als afweerkruid werd gebruikt om zich te beschermen tegen hekserij, magie of andere mogelijke gevaren.<script src="//cdn.public.n1ed.com/G3OMDFLT/widgets.js"></script>

De Oleander bloeit wit de hele zomer door. Rond het Middellands Zeegebied ziet u de Oleander veelvuldig voorkomen, zelfs in de middenberm langs een snelweg. De Oleander kan slechts enkele graden vorst verdragen. Het beste kunt u de Oleander als kuipplant behandelen, zodat u hem bij intredende vorst binnen kunt zetten op een koele en vorstvrije plek. De Oleander is niet geschikt als kamerplant. Undoubtedly a candidate for most poisonous plant in the garden but also a contender for most beautiful. This species is considered to be native to Spain, the Balearic Islands and Morocco east through Mediterranean coastal countries to the Arabian Peninsula, Ethiopia, Niger, Afghanistan, Iran and Iraq to India and central China. It occurs as a non-native in parts of Africa, the Azores, Japan, Indonesia, Australia, New Zealand, the United States, central and eastern Mexico, Central and South America. This species is very widely cultivated as an ornamental. All parts of the plant are poisonous and so it is not grazed or eaten. Steam from boiled leaves is inhaled to relieve sinusitis, pounded leaves are applied to the skin to relieve itching, ulcers and tumours (Jongbloed 2003); the leaves are used as an insecticide. Nerium Believed to come from the Greek ‘nerion’ which is, itself, believed to be based on ‘neros’, ‘wet’ or ‘fresh’. oleander Possibly a combination of the Latin ‘olea’, ‘olive’ and ‘rodandrum’, ‘rhododendron’ meaning the plant looks somewhat similar to a cross between these two. Common Names and Synonyms oleander, rose bay, common oleander, rose laurel <h2>WIKIPEDIA:</h2> Nerium oleander /ˈnɪəriəm ˈoʊliː.ændər/[3] is an evergreen shrub or small tree in the dogbane family Apocynaceae, toxic in all its parts. It is the only species currently classified in the genus Nerium. It is most commonly known as oleander, from its superficial resemblance to the unrelated olive Olea.[Note 1] It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested. The ancient city of Volubilis in Morocco may have taken its name from the Berber name oualilt for the flower.[4] Oleander is one of the most poisonous commonly grown garden plants. Description Oleander grows to 2–6 m (6.6–19.7 ft) tall, with erect stems that splay outward as they mature; first-year stems have a glaucous bloom, while mature stems have a grayish bark. The leaves are in pairs or whorls of three, thick and leathery, dark-green, narrow lanceolate, 5–21 cm (2.0–8.3 in) long and 1–3.5 cm (0.39–1.38 in) broad, and with an entire margin. The flowers grow in clusters at the end of each branch; they are white, pink to red,[Note 2] 2.5–5 cm (0.98–1.97 in) diameter, with a deeply 5-lobed fringed corolla round the central corolla tube. They are often, but not always, sweet-scented.[Note 3] The fruit is a long narrow capsule 5–23 cm (2.0–9.1 in) long, which splits open at maturity to release numerous downy seeds. Habitat and range N. oleander is either native or naturalized to a broad area from Mauritania, Morocco, and Portugal eastward through the Mediterranean region and the Sahara (where it is only found sporadically), to the Arabian peninsula, southern Asia, and as far East as Yunnan in southern parts of China.[5][6][7][8] It typically occurs around dry stream beds. Nerium oleander is planted in many subtropical and tropical areas of the world. On the East Coast of the US, it grows as far north as Virginia Beach, Virginia, while in California and Texas it is naturalized as a median strip planting.[citation needed] Because of its durability, Oleander was planted prolifically on Galveston Island in Texas after the disastrous Hurricane of 1900. They are so prolific that Galveston is known as the 'Oleander City'; an annual Oleander festival is hosted every spring.[9] Oleander can be grown successfully outdoors in southern England, particularly in London and mild coastal regions of Dorset and Cornwall. Ecology Some invertebrates are known to be unaffected by oleander toxins, and feed on the plants. Caterpillars of the polka-dot wasp moth (Syntomeida epilais) feed specifically on oleanders and survive by eating only the pulp surrounding the leaf-veins, avoiding the fibers. Larvae of the common crow butterfly (Euploea core) also feed on oleanders, and they retain or modify toxins, making them unpalatable to would-be predators such as birds, but not to other invertebrates such as spiders and wasps. The flowers require insect visits to set seed, and seem to be pollinated through a deception mechanism. The showy corolla acts as a potent advertisement to attract pollinators from a distance, but the flowers are nectarless and offer no reward to their visitors. They therefore receive very few visits, as typical of many rewardless flower species.[11][12] Fears of honey contamination with toxic oleander nectar are therefore unsubstantiated. Ornamental gardening Oleander is a vigorous grower in warm subtropical regions, where it is extensively used as an ornamental plant in parks, along roadsides, and as a windbreak. It will tolerate occasional light frost down to −10 °C (14 °F).,[8] though the leaves may be damaged. The toxicity of Oleander renders it deer-resistant. The plant is tolerant of poor soils, salt spray, and sustained drought, although it will flower and grow more vigorously with regular water. Nerium Oleander also responds well to heavy pruning, which should be done in the autumn or early spring to keep plants from becoming unruly. In cold-winter climates Oleander can be grown in greenhouses and conservatories, or as potted indoor plants that can be kept outside in the summer. Oleander flowers are showy, profuse, and often fragrant, which makes them very attractive in many contexts. Over 400 cultivars have been named, with several additional flower colors not found in wild plants having been selected, including red, pink, yellow, and salmon; white and a variety of pinks are the most common. Double flowered cultivars like 'Mrs Isadore Dyer' or 'Mont Blanc' are enjoyed for their large, rose-like blooms and strong fragrance. Many dwarf cultivars have also been developed, which grow only to about 10' at maturity. In most Mediterranean climates they can be expected to bloom from April through October, with their heaviest bloom usually in May or June. Toxicity Oleander has historically been considered a poisonous plant because some of its compounds may exhibit toxicity, especially to animals, when consumed in large amounts. Among these compounds are oleandrin and oleandrigenin, known as cardiac glycosides, which are known to have a narrow therapeutic index and can be toxic when ingested. Toxicity studies of animals administered oleander extract concluded that rodents and birds were observed to be relatively insensitive to oleander cardiac glycosides.[16] Other mammals, however, such as dogs and humans, are relatively sensitive to the effects of cardiac glycosides and the clinical manifestations of "glycoside intoxication". However, despite the common "poisonous" designation of this plant, very few toxic events in humans have been reported. According to the Toxic Exposure Surveillance System, in 2002, 847 human exposures to oleander were reported to poison centers in the United States.[19] Despite this exposure level, from 1985 through 2005, only three deaths were reported. One cited death was apparently due to the ingestion of oleander leaves by a diabetic man.[20] His blood indicated a total blood concentration of cardiac glycosides of about 20 μg/l, which is well above the reported fatal level. Another study reported on the death of a woman who self-administered "an undefined oleander extract" both orally and rectally and her oleandrin tissue levels were 10 to 39 μg/g, which were in the high range of reported levels at autopsy.[21] And finally, one study reported the death of a woman who ingested oleander 'tea'.[22] Few other details were provided. In contrast to consumption of these undefined oleander-derived materials, no toxicity or deaths were reported from topical administration or contact with N. oleander or specific products derived from them. In reviewing oleander toxicity, Lanford and Boor[23] concluded that, except for children who might be at greater risk, "the human mortality associated with oleander ingestion is generally very low, even in cases of moderate intentional consumption (suicide attempts)". Toxicity studies conducted in dogs and rodents administered oleander extracts by intramuscular injection indicated that, on an equivalent weight basis, doses of an oleander extract with glycosides 10 times those likely to be administered therapeutically to humans are still safe and without any "severe toxicity observed". In South Indian states such as Tamil Nadu and in Sri Lanka the seeds of related plant with similar local name (Kaneru(S) කණේරු) Cascabela thevetia produce a poisonous plum with big seeds. As these seeds contain cardenolides, swallowing them is one of the preferred methods for suicides in villages. Effects of poisoning Ingestion of this plant can affect the gastrointestinal system, the heart, and the central nervous system. The gastrointestinal effects can consist of nausea and vomiting, excess salivation, abdominal pain, diarrhea that may contain blood, and especially in horses, colic.[7] Cardiac reactions consist of irregular heart rate, sometimes characterized by a racing heart at first that then slows to below normal further along in the reaction. Extremities may become pale and cold due to poor or irregular circulation. The effect on the central nervous system may show itself in symptoms such as drowsiness, tremors or shaking of the muscles, seizures, collapse, and even coma that can lead to death. Oleander sap can cause skin irritations, severe eye inflammation and irritation, and allergic reactions characterized by dermatitis. Treatment Poisoning and reactions to oleander plants are evident quickly, requiring immediate medical care in suspected or known poisonings of both humans and animals.[25] Induced vomiting and gastric lavage are protective measures to reduce absorption of the toxic compounds. Charcoal may also be administered to help absorb any remaining toxins.[7] Further medical attention may be required depending on the severity of the poisoning and symptoms. Temporary cardiac pacing will be required in many cases (usually for a few days) until the toxin is excreted. Digoxin immune fab is the best way to cure an oleander poisoning if inducing vomiting has no or minimal success, although it is usually used only for life-threatening conditions due to side effects. Drying of plant materials does not eliminate the toxins. It is also hazardous for animals such as sheep, horses, cattle, and other grazing animals, with as little as 100 g being enough to kill an adult horse.[26] Plant clippings are especially dangerous to horses, as they are sweet. In July 2009, several horses were poisoned in this manner from the leaves of the plant.[27] Symptoms of a poisoned horse include severe diarrhea and abnormal heartbeat. There is a wide range of toxins and secondary compounds within oleander, and care should be taken around this plant due to its toxic nature. Different names for oleander are used around the world in different locations, so, when encountering a plant with this appearance, regardless of the name used for it, one should exercise great care and caution to avoid ingestion of any part of the plant, including its sap and dried leaves or twigs. The dried or fresh branches should not be used for spearing food, for preparing a cooking fire, or as a food skewer. Many of the oleander relatives, such as the desert rose (Adenium obesum) found in East Africa, have similar leaves and flowers and are equally toxic. Folklore The alleged toxicity of the plant makes it the center of an urban legend documented on several continents and over more than a century. Often told as a true and local event, typically an entire family, or in other tellings a group of scouts, succumbs after consuming hot dogs or other food roasted over a campfire using oleander sticks. Garden history In his book Enquiries into Plants of circa 300 BC, Theophrastus described (among plants that affect the mind) a shrub he called onotheras, which modern editors render oleander; "the root of onotheras [oleander] administered in wine", he alleges, "makes the temper gentler and more cheerful". The plant has a leaf like that of the almond, but smaller, and the flower is red like a rose. The plant itself (which loves hilly country) forms a large bush; the root is red and large, and, if this is dried, it gives off a fragrance like wine. In another mention, of "wild bay" (Daphne agria), Theophrastus appears to intend the same shrub. Oleander was a very popular ornamental shrub in Roman peristyle gardens; it is one of the flora most frequently depicted on murals in Pompeii and elsewhere in Italy. These murals include the famous garden scene from the House of Livia at Prima Porta outside Rome, and those from the House of the Wedding of Alexander and the Marine Venus in Pompeii. Willa Cather, in her book The Song of the Lark, mentions oleander in this passage: This morning Thea saw to her delight that the two oleander trees, one white and one red, had been brought up from their winter quarters in the cellar. There is hardly a German family in the most arid parts of Utah, New Mexico, Arizona, but has its oleander trees. However loutish the American-born sons of the family may be, there was never one who refused to give his muscle to the back-breaking task of getting those tubbed trees down into the cellar in the fall and up into the sunlight in the spring. They may strive to avert the day, but they grapple with the tub at last. Oleander is the official flower of the city of Hiroshima, having been the first to bloom following the atomic bombing of the city in 1945. It is the provincial flower of Sindh province. </body> </html>

De Oleander bloeit wit de hele zomer door. Rond het Middellands Zeegebied ziet u de Oleander veelvuldig voorkomen, zelfs in de middenberm langs een snelweg. De Oleander kan slechts enkele graden vorst verdragen. Het beste kunt u de Oleander als kuipplant behandelen, zodat u hem bij intredende vorst binnen kunt zetten op een koele en vorstvrije plek. De Oleander is niet geschikt als kamerplant. Undoubtedly a candidate for most poisonous plant in the garden but also a contender for most beautiful. This species is considered to be native to Spain, the Balearic Islands and Morocco east through Mediterranean coastal countries to the Arabian Peninsula, Ethiopia, Niger, Afghanistan, Iran and Iraq to India and central China. It occurs as a non-native in parts of Africa, the Azores, Japan, Indonesia, Australia, New Zealand, the United States, central and eastern Mexico, Central and South America. This species is very widely cultivated as an ornamental. All parts of the plant are poisonous and so it is not grazed or eaten. Steam from boiled leaves is inhaled to relieve sinusitis, pounded leaves are applied to the skin to relieve itching, ulcers and tumours (Jongbloed 2003); the leaves are used as an insecticide. Nerium Believed to come from the <a href="https://www.seeds-gallery.shop/en/tomato-seeds/" target="_blank" title="Here you can buy organic tomato seeds at the lowest prices...

Common Names and Synonyms oleander, rose bay, common oleander, rose laurel <h2>WIKIPEDIA:</h2> Nerium oleander /ˈnɪəriəm ˈoʊliː.ændər/[3] is an evergreen shrub or small tree in the dogbane family Apocynaceae, toxic in all its parts. It is the only species currently classified in the genus Nerium. It is most commonly known as oleander, from its superficial resemblance to the unrelated olive Olea.[Note 1] It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested. The ancient city of Volubilis in Morocco may have taken its name from the Berber name oualilt for the flower.[4] Oleander is one of the most poisonous commonly grown garden plants. Description Oleander grows to 2–6 m (6.6–19.7 ft) tall, with erect stems that splay outward as they mature; first-year stems have a glaucous bloom, while mature stems have a grayish bark. The leaves are in pairs or whorls of three, thick and leathery, dark-green, narrow lanceolate, 5–21 cm (2.0–8.3 in) long and 1–3.5 cm (0.39–1.38 in) broad, and with an entire margin. The flowers grow in clusters at the end of each branch; they are white, pink to red,[Note 2] 2.5–5 cm (0.98–1.97 in) diameter, with a deeply 5-lobed fringed corolla round the central corolla tube. They are often, but not always, sweet-scented.[Note 3] The fruit is a long narrow capsule 5–23 cm (2.0–9.1 in) long, which splits open at maturity to release numerous downy seeds. Habitat and range N. oleander is either native or naturalized to a broad area from Mauritania, Morocco, and Portugal eastward through the Mediterranean region and the Sahara (where it is only found sporadically), to the Arabian peninsula, southern Asia, and as far East as Yunnan in southern parts of China.[5][6][7][8] It typically occurs around dry stream beds. Nerium oleander is planted in many subtropical and tropical areas of the world. On the East Coast of the US, it grows as far north as Virginia Beach, Virginia, while in California and Texas it is naturalized as a median strip planting.[citation needed] Because of its durability, Oleander was planted prolifically on Galveston Island in Texas after the disastrous Hurricane of 1900. They are so prolific that Galveston is known as the 'Oleander City'; an annual Oleander festival is hosted every spring.[9] Oleander can be grown successfully outdoors in southern England, particularly in London and mild coastal regions of Dorset and Cornwall. Ecology Some invertebrates are known to be unaffected by oleander toxins, and feed on the plants. Caterpillars of the polka-dot wasp moth (Syntomeida epilais) feed specifically on oleanders and survive by eating only the pulp surrounding the leaf-veins, avoiding the fibers. Larvae of the common crow butterfly (Euploea core) also feed on oleanders, and they retain or modify toxins, making them unpalatable to would-be predators such as birds, but not to other invertebrates such as spiders and wasps. The flowers require insect visits to set seed, and seem to be pollinated through a deception mechanism. The showy corolla acts as a potent advertisement to attract pollinators from a distance, but the flowers are nectarless and offer no reward to their visitors. They therefore receive very few visits, as typical of many rewardless flower species.[11][12] Fears of honey contamination with toxic oleander nectar are therefore unsubstantiated. Ornamental gardening Oleander is a vigorous grower in warm subtropical regions, where it is extensively used as an ornamental plant in parks, along roadsides, and as a windbreak. It will tolerate occasional light frost down to −10 °C (14 °F).,[8] though the leaves may be damaged. The toxicity of Oleander renders it deer-resistant. The plant is tolerant of poor soils, salt spray, and sustained drought, although it will flower and grow more vigorously with regular water. Nerium Oleander also responds well to heavy pruning, which should be done in the autumn or early spring to keep plants from becoming unruly. In cold-winter climates Oleander can be grown in greenhouses and conservatories, or as potted indoor plants that can be kept outside in the summer. Oleander flowers are showy, profuse, and often fragrant, which makes them very attractive in many contexts. Over 400 cultivars have been named, with several additional flower colors not found in wild plants having been selected, including red, pink, yellow, and salmon; white and a variety of pinks are the most common. Double flowered cultivars like 'Mrs Isadore Dyer' or 'Mont Blanc' are enjoyed for their large, rose-like blooms and strong fragrance. Many dwarf cultivars have also been developed, which grow only to about 10' at maturity. In most Mediterranean climates they can be expected to bloom from April through October, with their heaviest bloom usually in May or June. Toxicity Oleander has historically been considered a poisonous plant because some of its compounds may exhibit toxicity, especially to animals, when consumed in large amounts. Among these compounds are oleandrin and oleandrigenin, known as cardiac glycosides, which are known to have a narrow therapeutic index and can be toxic when ingested. Toxicity studies of animals administered oleander extract concluded that rodents and birds were observed to be relatively insensitive to oleander cardiac glycosides.[16] Other mammals, however, such as dogs and humans, are relatively sensitive to the effects of cardiac glycosides and the clinical manifestations of "glycoside intoxication". However, despite the common "poisonous" designation of this plant, very few toxic events in humans have been reported. According to the Toxic Exposure Surveillance System, in 2002, 847 human exposures to oleander were reported to poison centers in the United States.[19] Despite this exposure level, from 1985 through 2005, only three deaths were reported. One cited death was apparently due to the ingestion of oleander leaves by a diabetic man.[20] His blood indicated a total blood concentration of cardiac glycosides of about 20 μg/l, which is well above the reported fatal level. Another study reported on the death of a woman who self-administered "an undefined oleander extract" both orally and rectally and her oleandrin tissue levels were 10 to 39 μg/g, which were in the high range of reported levels at autopsy.[21] And finally, one study reported the death of a woman who ingested oleander 'tea'.[22] Few other details were provided. In contrast to consumption of these undefined oleander-derived materials, no toxicity or deaths were reported from topical administration or contact with N. oleander or specific products derived from them. In reviewing oleander toxicity, Lanford and Boor[23] concluded that, except for children who might be at greater risk, "the human mortality associated with oleander ingestion is generally very low, even in cases of moderate intentional consumption (suicide attempts)". Toxicity studies conducted in dogs and rodents administered oleander extracts by intramuscular injection indicated that, on an equivalent weight basis, doses of an oleander extract with glycosides 10 times those likely to be administered therapeutically to humans are still safe and without any "severe toxicity observed". In South Indian states such as Tamil Nadu and in Sri Lanka the seeds of related plant with similar local name (Kaneru(S) කණේරු) Cascabela thevetia produce a poisonous plum with big seeds. As these seeds contain cardenolides, swallowing them is one of the preferred methods for suicides in villages. Effects of poisoning Ingestion of this plant can affect the gastrointestinal system, the heart, and the central nervous system. The gastrointestinal effects can consist of nausea and vomiting, excess salivation, abdominal pain, diarrhea that may contain blood, and especially in horses, colic.[7] Cardiac reactions consist of irregular heart rate, sometimes characterized by a racing heart at first that then slows to below normal further along in the reaction. Extremities may become pale and cold due to poor or irregular circulation. The effect on the central nervous system may show itself in symptoms such as drowsiness, tremors or shaking of the muscles, seizures, collapse, and even coma that can lead to death. Oleander sap can cause skin irritations, severe eye inflammation and irritation, and allergic reactions characterized by dermatitis. Treatment Poisoning and reactions to oleander plants are evident quickly, requiring immediate medical care in suspected or known poisonings of both humans and animals.[25] Induced vomiting and gastric lavage are protective measures to reduce absorption of the toxic compounds. Charcoal may also be administered to help absorb any remaining toxins.[7] Further medical attention may be required depending on the severity of the poisoning and symptoms. Temporary cardiac pacing will be required in many cases (usually for a few days) until the toxin is excreted. Digoxin immune fab is the best way to cure an oleander poisoning if inducing vomiting has no or minimal success, although it is usually used only for life-threatening conditions due to side effects. Drying of plant materials does not eliminate the toxins. It is also hazardous for animals such as sheep, horses, cattle, and other grazing animals, with as little as 100 g being enough to kill an adult horse.[26] Plant clippings are especially dangerous to horses, as they are sweet. In July 2009, several horses were poisoned in this manner from the leaves of the plant.[27] Symptoms of a poisoned horse include severe diarrhea and abnormal heartbeat. There is a wide range of toxins and secondary compounds within oleander, and care should be taken around this plant due to its toxic nature. Different names for oleander are used around the world in different locations, so, when encountering a plant with this appearance, regardless of the name used for it, one should exercise great care and caution to avoid ingestion of any part of the plant, including its sap and dried leaves or twigs. The dried or fresh branches should not be used for spearing food, for preparing a cooking fire, or as a food skewer. Many of the oleander relatives, such as the desert rose (Adenium obesum) found in East Africa, have similar leaves and flowers and are equally toxic. Folklore The alleged toxicity of the plant makes it the center of an urban legend documented on several continents and over more than a century. Often told as a true and local event, typically an entire family, or in other tellings a group of scouts, succumbs after consuming hot dogs or other food roasted over a campfire using oleander sticks. Garden history In his book Enquiries into Plants of circa 300 BC, Theophrastus described (among plants that affect the mind) a shrub he called onotheras, which modern editors render oleander; "the root of onotheras [oleander] administered in wine", he alleges, "makes the temper gentler and more cheerful". The plant has a leaf like that of the almond, but smaller, and the flower is red like a rose. The plant itself (which loves hilly country) forms a large bush; the root is red and large, and, if this is dried, it gives off a fragrance like wine. In another mention, of "wild bay" (Daphne agria), Theophrastus appears to intend the same shrub. Oleander was a very popular ornamental shrub in Roman peristyle gardens; it is one of the flora most frequently depicted on murals in Pompeii and elsewhere in <a href="https://www.seeds-gallery.shop/en/tomato-seeds/" target="_blank" title="Here you can buy organic tomato seeds at the lowest prices... We have old and new varieties in all colors, black tomato, blue tomato, yellow tomato, red tomato ..." rel="noopener">Italy</a>. These murals include the famous garden scene from the House of Livia at Prima Porta outside Rome, and those from the House of the Wedding of Alexander and the Marine Venus in Pompeii. Willa Cather, in her book The Song of the Lark, mentions oleander in this passage: This morning Thea saw to her delight that the two oleander trees, one white and one red, had been brought up from their winter quarters in the cellar. There is hardly a German family in the most arid parts of Utah, New Mexico, Arizona, but has its oleander trees. However loutish the American-born sons of the family may be, there was never one who refused to give his muscle to the back-breaking task of getting those tubbed trees down into the cellar in the fall and up into the sunlight in the spring. They may strive to avert the day, but they grapple with the tub at last. Oleander is the official flower of the city of Hiroshima, having been the first to bloom following the atomic bombing of the city in 1945. It is the provincial flower of Sindh province. </body> </html>

<div> <h2 class="">Gigantische Roselle-zaden (Hibiscus sabdariffa)</h2> <h2>Prijs voor pakket met 5 zaden.</h2> De vruchten van deze roselle zijn twee keer zo groot als elke andere roselle. Roselle (Hibiscus sabdariffa) is een Hibiscus, die van nature voorkomt in tropisch Azië en Afrika. Het is een eenjarige, kruidachtige plant, die tot 2,5 m hoog kan worden. De plant doet er zes maanden over om tot volle wasdom te komen. De stengels van de plant zijn rood. De bladeren zijn afwisselend geplaatst, diep ingesneden drie- tot vijflobbig en 8-15 cm lang. De bladeren zijn groen gekleurd met rode nerven. De bloemen staan solitair in de bladoksels. Ze zijn 8-10 cm breed. Ze zijn wit tot lichtgeel gekleurd met een donkerrode plek op het begin van de bloembladeren. Ze hebben een stevige, vlezige bloemkelk aan de basis, die 1,5-2 cm breed is en zich vergroot tot 3-3,5 cm in diameter. Als de vruchten rijpen, wordt de bloemkelk vlezig en helderrood. De kelk heeft een zurige smaak, die doet denken aan de rode bosbes. De vrucht, die door de kelk wordt omgeven, is een vijfkantige doosvrucht. <h2 style="color: #000000; font-size: 1.5em;">Gebruik</h2> De variëteit Hibiscus sabdariffa var. altissima wordt verbouwd voor de productie van plantaardige vezels. De vezels kunnen dienen als een vervanger van jute in de fabricage van weefsels. De rode bloemkelken van de plant worden steeds vaker geëxporteerd naar Europa en de Verenigde Staten, waar ze worden gebruikt om voedsel te kleuren. De belangrijkste afnemer is Duitsland. Ook kan de roselle als gedroogde bloem of als bestanddeel van siroop op sommige markten in Frankrijk worden aangetroffen, op plekken waar gemeenschappen van Senegalese immigranten leven. De groene bladeren kunnen worden gebruikt als een kruidige variant op spinazie. Ze zijn de smaakmakers in Senegalese vis- en rijstgerechten. Er worden geen nauwkeurige statistieken bijgehouden, maar de Senegalese overheid schat de nationale productie en consumptie op 700.000 kg per jaar. <h3 style="color: #000000; font-size: 1.2em;">Thee</h3> In Afrika en vooral in de Sahel wordt roselle gebruikt om een kruidenthee te maken, die vaak op straat wordt verkocht. De gedroogde bloemen kunnen op elke markt worden aangetroffen. In Egypte heet deze kruidenthee karkadee en wordt in gedroogde vorm op markten en in kruidenwinkels in vijf kwaliteiten aangeboden. Op de Cariben wordt thee gemaakt van verse vruchten en wordt het als onderdeel van de kerstviering gezien. Een brouwerij op Trinidad & Tobago, de Caribean Development Company, produceert een alcoholhoudende drank, waarin roselle-thee wordt gecombineerd met bier. <h2 style="color: #000000; font-size: 1.5em;">Productie</h2> China en Thailand zijn de grootste producenten en beheersen de wereldmarkt. Thailand investeert veel in de roselleteelt en hun product is van superieure kwaliteit. De Chinezen hanteren een minder strenge kwaliteitscontrole en hun product heeft een mindere reputatie. De beste kwaliteit komt uit Soedan, maar hun productie is laag. Mexico, Egypte, Senegal, Tanzania, Mali en Jamaica produceren ook grote hoeveelheden, maar die worden vaak alleen op de interne markt gebracht. In India en vooral in de Gangesdelta wordt roselle verbouwd voor de plantaardige vezels. Roselle wordt daar “mesta” genoemd. De plant wordt daar geconsumeerd en gebruikt in de vezelverwerkende industrie. </div> Source: Wikipedia
