Sauromatum guttatum or Dracunculus vulgaris?

northerner_on(Z5A ONCanada)August 2, 2010

Two years ago I was offered two tubers of what was described as Voodoo Lily. The two tubers were the size of dimes which I planted in 1/2 gallon pots. They grew, beautiful and unusual foliage, were overwintered and again they have produced this beautiful foliage. One has even split and produced an additional shoot. Now that I am ready to pay attention to this plant I identified it as Sauromatum guttatum through a google search (these are hardy to Zone 6a). Now I have found a post on this forum describing Dracunculus vulgaris (hardy to Zone 10/11) but seemingly the same plant. Is this just a matter of re-classification or are these two different plants? I was toying with the idea of planting one of my plants outdoors in a sheltered area with lots of mulch to see if I could get a bloom, but I don't have a definitive ID. There was someone in Zone 5 (US) who reported growing it on this Forum, so I thought I might risk it. So my questions: are these the same plant? If not, how do I know which one I have? Has anyone in a snow belt (below zero for several months and lots of snow) grown it, and how did you get it through the winter? Thank you very much.

According to the World Checklist of Selected Plant Families, Sauromatum guttatum and all its variations are synonyms of Typhonium venosum

Dracunculus vulgaris Schott is an accepted species name. The two are not related.

The World Checklist is a project of the Royal Botanic Garden Kew in London.

Google search and especially the photos cannot always be trusted for accuracy. A better source is the International Aroid Society, www.Aroid.org. Sorry, I can't put links to both in a single thread.

Steve, thank you so much for the links. I will have to take some time to go through them and come to a conclusion. I think I will still take the risk and try one outdoors over winter. I will still have two left and then the adventure will continue.
