Talk:Cosmos atrosanguineus

This plant is listed in the extinct plants page. That may be an issue since this article is in the present tense an does not refer to the plant being extinct. Is it extinct or not? Sifaka 21:33, 9 March 2006 (UTC)

Cosmos atrosanguineus is extinct in the wild (Mexico, 1902) but in its cultivated form it is a famous garden plant --Melly42 05:23, 27 March 2006 (UTC)

This text was removed from the article because it repeated a lot of what was already said, was out of place, and may well have been plagiarized.

Cosmos atrosanguineus This is an attractive, popular, chocolate-scented garden plant, but is believed to be extinct in the wild. It was first discovered in Mexico in the 1860s, and has remained in cultivation ever since, gaining an RHS Award of Merit for Exhibition in 1938. It has not, however, been re-discovered in the wild, although plants are now being re-introduced from micropropagated material at the Royal Botanic Gardens, Kew. Until recently, all the plants in cultivation were thought to be a single clone that was self-incompatible and therefore did not set seed. A fertile form called ‘Pinot Noir’ has now been introduced to cultivation from New Zealand and is protected in most countries by Plant Breeders’ Rights. Cosmos atrosanguineus is widely available, but the cultivar ‘Pinot Noir’ has not yet made it into the RHS Plant Finder – maybe next year?

If somebody wants to put it back in, be my guest. HoCkEy PUCK 20:08, 12 April 2007 (UTC)

Cosmos atrosanguineus is not extinct in the wild, and more than one clone is cultivated

Fred Boutin relates on the Pacific Bulb Society mailiing list that he has collected seed of this plant in Jalisco, Mexico:

http://www.pacificbulbsociety.org/pbslist/2012-September/#year=2006&month=6&id=ub8es5snq4622anrcjfjevmdc2

I believe this is adequate as a reference, as it is a first hand account.

In private email I have been informed that a number of cultivars (hence, distinct clones) are and have been in cultivation. Among them: 'Chocolate' (a Japanese cultivar); 'Chocamocha' (bred by the English seed company Thompson & Morgan); 'Black Beauty', grown in the Netherlands as a cut flower; 'New Choco' (from Japan). I have requested references for these as a prerequisite to correcting this article.

A plant patent for a cultivar of C.a. is here:

To summarize, there are three myths about Cosmos atrosanguineus that are simply wrong:

1. That a single clone is in cultivation. 2. That it is extinct in the wild. 3. That it never sets seed - as I write my own plants, including a potful grown from seed, are ripening seed.

Merger proposal

I support the idea of moving the contents of the rather silly stand-alone article entitled Chocolate cosmos (color) into this one, and deleting the former. Nick Moyes (talk) 15:28, 17 September 2017 (UTC)

Seconded. There wasn't much over there, so I just went ahead and merged them myself Sesamehoneytart 00:58, 21 September 2017 (UTC)

Beware of original research

Someone at some point added the claim that "chocolate cosmos" is a color in art. Good luck finding a source for that! It's a load of baloney.104.163.155.95 (talk) 04:14, 9 November 2017 (UTC)
