Norman Deno's research shows that A.flavum doesn't need cold for
germination, though it might speed it up.

Apropos of this.  I gave A. yunnanense seeds to the Seedex and didn't kee=p
any for myself believing that I'd be just fine with the two tubers that
produced the seed.  Alas...  Chipmunks dug up and carried away the tubers.

So. Two questions, the first is:  How was germination?  Answers  please,
from those who got this  species.  Does anybody else in the U.S.have this
species?  and-- Can you share?.
