Asarum weediness etc.

Dear Roy and all,
	My climate is pretty harsh. I've tried caulescens and it too 
lasted a few years, but then some seasonal extreme took it too. It is 
even more generic than A canadense. I like the small delicate form, 
but not very exciting either.

	Yes of course I meant A. splendens - duh! I brought back a 
couple clones from China in '89 or so and eventually gave a bunch to 
Tony A who sold it for years. It was never hardy enough to make it 
through more than 1 winter. We rarely get extended snow cover like 
Ellen does.  It and a few other large flower Chinese Asarum did fine 
in pots in a frost free greenhouse, but these all went away

	This looks pretty nice and your description is better.

	Worth a try. Many thanks

	Yes I first grew this from the Nat. Arb too in the 90s and it 
was remarkably easy from seed.  I certainly recommend it to anyone in 
a variety of climates. If it grows here, it should grow almost 

	While going wildly off topic (sorry folks) , have you ever 
grown any species of Thottea, the 'other' Aristolochid from China? 
The genus has 3 or 4 or 10 ? species and are mostly tender, but....

	Anyone else in cooler climates have success with these 
ornamental Asaum species?

	I think they might all be rhizomatous and thus fodder for 
PBS, but that is pushing things a bit.
