Dioscorea help

Jan,

There is unfortunately no modern magnum opus on Dioscorea and it is
quite a large and rather poorly understood genus. There are a few
specialists (I know two of them) but they are restricted
geographically or to a certain section of the genus.

So, if you know where your plant is from you may discover a local
flora and find a name for it. But it sounds like you have names for
most of yours-- what information are you after?

Regards,

Dylan

Dear Dylan,

I got 1 from a botanical garden, they were so generous with me, cause I have
helped them with some "charity work". And from a wholesaler. I have D.
villosa from US. They have arrived with wild dug Trilliums, and D. caucasica
(female). They are hardy here. I have a few other plants from seed, but not
sure in the identity. I have noticed D. villosa from a batch of seedlings
between D. caucasica.

D. balcanica and D. bulbifera have died this winter, forgot to put them in a
frost free place, -10°C killed most of the tubers, but maybe D. balcanica
will resurrect. I try to plant them again. I try to get D. balcanica from
Macedonia, it is said to be native there.

I have new seeds, but they emerge after a cold winter, haven't sown yet.
Most of my plants from seed are now 3 years old, some started to make
inflorescences. And I'm trying to germinate Tamus communis, no success till
now.

We don't have so much climbing geophytes in commerce (Gloriosa, rarely
Sandersonia and ever rarer Littonia, but none of them are hardy).

Bye,
Jan
