Tony and Dennis, I don't dare grow Asarum canadense in my garden due to it's invasiveness. Fortunately the seeds are decidedly ephemeral, so if Dennis sends any to the BX there is a limited risk of having them germinate and infest other gardens. As for Asarum europaeum, it is one of our most invasive aliens. Can't kill it, even the voles hate it. If hybrid vigor is real, I would be very wary of a hybrid with canadense. I like other plain old green asarums, and find the evergreen A. caudatum to be much better behaved than the dedidous A. canadense. The white flowered album type is nice if you are willing to look under the leaves for enlightenment. Another well-behaved but vigorous green one is the deciduous A. caulescens, honored by the Japanese nobility in their family crests. Then there are all those fancy ones, which are another story altogether... --Roy NW of Boston Tony Avent wrote: > John: > > One of my friends in Michigan just found something interesting the other week. A nursery there is selling seed grown Asarum europeum...only the plants they are selling are obvious hybrids with Asarum canadense. Who knew? >
