All;
I have had luck growing A nigrum in my Zone 5/6 -blooms,but no seed
A dioscorides did well in my in-town garden, not on the more
exposed north side of town I now garden in.

Have A.x(?) 'Chameleon' and it is gorgeous. Hasn't bloom yet,
but I hope it does to collect more seed. Does this hybrid make seed?

and an un-named all green foliage sp. I hope will bloom this
coming season and reveal it's ID.
I have purpureospathum in a cold greenhosue and have been
wimpy to try it outside.

Just potted A idaeum, but hope it too might be hardy.


and of course italicum and maculatum

Semi-similar in the garden are the Pinellia species and
Arisarum proboscidium.

Eager to hear of other successes to try.        Jim W.
