Hello Oleg: A. griffithii is not indicated as hardy beyond 5b on any list
I am aware of, however, Archibald collected it at 13,000ft. in Nepal on one
occasion, so I would guess that it might be all right in areas colder than Z
5 depending on where the original tubers were collected. The same caution
applies to all which have ranges over 3 or 4 climatic zones. Individual
clones vary a lot.
The latest list from the International Aroid Society indicates that
concinnum is hardy to Z 6 (Arkansas record) ,galeatum to Z 5a (Iowa),
speciosum Z 7, costatum Z 7, and , tortuosum Z4b (Ithaca New York). L.
nepalense, I would expdect would be worth trying in Z 5, Paris polyphylla
probably OK to Z 4 (Iowa) and maybe cooler, Disporum cantonense (since it's
from southern China probably not below Z6-7, but???) and Roscoea purpurea.
no data. ???
I've not grown any of these, but this is data in my files. Others may have
better information. Regards.
Adam Fikso, Chicago area Z5a.
