Here in Raleigh, NC, USA, USDA-zone#7, the following are also
cold hardy:
Amorphophallus napalensis
Amorphophallus odoratus
I'm testing/will be testing the following for cold-hardiness:
Amorphophallus henryii
Amorphophallus kisusianus
Amorphophallus albus

It is extremely cold hardy, as is Typhonium roxburghii (formerly T.
diveracatum).
