Asarum weediness etc.

When our friend Hans Hansen lived in Minnesota, he had great luck with A. takoi, Asarum debile, and Asarum sieboldii...all without reliable snow cover.  I know there were others, but these are the ones that I remember.

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.

                Thanks for your patience.               Jim W.
