Removed bad citation

[edit]

I removed a reference: http://toptropicals.com/cgi-bin/garden_catalog/cat.cgi?number=5&op=OR&first=1&v1=poi It fails to mention anything about the plant being used as a poison in hunting (which is the sentence it was a citation for). I replaced it with a reference that does state this. Timothykinney 17:55, 28 July 2010 (UTC)[reply]

Misc

[edit]

In searching Adenium I find arabicum and multiflorum listed as species, along with swazicum and oleifolum, which are listed here as subspecies. I don't know: is there an authoritative taxonomic authority? if so, a link would be appreciated. 140.184.192.117 16:50, 17 April 2007 (UTC)[reply]

I'm watching a BBC program called "tribe" where the presenter stays with remote tribes and lives their life. In this case, a tribe in tanzinia is observed using poison from "a tree called the desert rose" to poison their arrows for hunting. He said that there is no known cure for this poison, so I came here looking. Is this the same plant? And what of the poison?


All parts of this plant are poisonous, with the toxic action due to cardioactive steroids resembling digitalis. See, for example, 2d Ed. Handbook of Poisonous and Injurious Plants by Nelson, Shih, and Balick. —Preceding unsigned comment added by 12.5.158.2 (talk) 18:42, 30 December 2007 (UTC)[reply]

From disambig page

[edit]

The disambiguation page Desert rose links to this article. User 123.211.238.78 (talk · contribs) recently replaced the entire disambig page with the following gardener-orientated content. I've restored the disambig page and moved the content here in case it is useful in the article. Cheers, CWC 12:38, 19 April 2010 (UTC)[reply]

Some gardeners may not be familiar with the hardy succulent Adenium. They remind Leonie of "contented boabs with their fantastic rounded, twisted sculptured shapes." Their flowers are spectacular.

Adeniums are commonly known as Desert Roses. The 'desert' part is correct as they come from Africa and the Middle East, but they’re certainly not roses. Adenium obesium, as they’re commonly known, are actually more related to Alamandas, Oleanders and Frangipanis.


• Habit: They grow to about 2 metres high, and love hot, tropical climates. Ideal growing conditions include full sun and rich, well-drained soil.

• Water: A common misconception is that they don’t need much water or attention. Leonie says, "They are tough plants, but they’re surprisingly sensitive to how much water they get – too much and they’ll rot; too little and they’ll stress and drop their flowers." During the dry season in the top end, water them every day when it’s cool in either the morning or the afternoon. During the wet season, reduce this rate depending on the rain. Water the soil and avoid the leaves, and don’t sit your Adenium in a saucer of water because it may rot.

• Media: Adeniums like an open, well-drained media, so use one part vermiculite to two parts quality potting mix. Fertilise with a slow release fertiliser every 8 months or so and a liquid seaweed tonic every fortnight.

• Pests: They aren’t bothered by many pests. A bit of white oil takes care of insects such as aphids or mealy bugs.

• Propagating: Adenium seed pods come in pairs and they’re filled with dandelion-like fluffy seeds. Separate the seeds and plant densely into the media. Cover with a bit of soil and in a month’s time they’ll be crowded and ready to pot on into individual pots. Seeds are not necessarily 'true to type' meaning that a plant with white flowers may produce offspring with different colours. But Adeniums grown from cuttings tend to be a bit scraggly, so propagating from seeds is the best way to get lovely fat trunks.

• Grafting: This is the fastest way to get another adult flowering plant. Grafting a branch from a plant with the flower colour you want onto root stock will produce an adult plant with the desired flower colour quite quickly. There are many different grafting techniques, but Leonie explains an easy one: "Take your graft, trim off all the leaves except a few at the top. Using a sharp knife, make a 'V' in the bottom of the stem. In your root stock, make a slice about the same length of the 'V', insert the stem and press them together making sure all the surfaces make good contact. Bind the graft with horticultural tape and cover with a plastic bag for about a week to minimise moisture loss. Adeniums can be a bit sappy so use methylated spirits to clean the knife blade. This will also help stop any infections spreading between the plants.

• Repotting: Each time you re-pot, the plant should sit a bit higher. This encourages the roots down further and the cortex to sit above the surface of the soil and fill out more. Eventually you’ll get a beautiful, fat, happy Adenium.

• Pruning: In the wet season, the chance of getting rot in the open wounds is very high, so prune during the dry season. Pruning will improve the shape and encourage more branches and flowers.

Adenium socotranum

Much larger than the other specie in this genus, more a tree than a shrub. From Socotra Island, Yemen. 109.144.219.169 (talk) 15:15, 23 March 2020 (UTC)[reply]
