Asarum canadense

Interesting that one mans weed in another mans treasure.  We can barely grow Asarum europeum here...evidently most of what is in the trade is from a cooler region.  Asarum canandense does have weed status here, but that's okay since it is native.

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...
