Dracunculus vulgaris survived Winter in Zone 5. Three bulbs were placed in the garden is 2006/2007 and all three survived the Winter much to my suprise. It appears one has even divided. The vegetation completely disappeared during the summer. I notice growth is most vigorous, and it started growth immediately after the snow disappeared. http://iomahj.notlong.com 27 April 2008 Dracunculus vulgaris. It should be in bloom soon. http://www.paghat.com/voodoolily.html Detailed information about this plant. One was grown indoors last year and it flowered. It has an odour for a day or so, similiar to the odour of a rancid sea shell, but very over-powering, if very close to the flowering part of the plant.
