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 > > I am also after similar temperature information for Alocasias, Colocasias, > Typhoniums and Xanthosoma species. I was reading back through some of the > stuff that I've saved regarding aroids and noticed that one person in Zone > 5 mentioned that Typhonium giganteum was hardy there (I assume dormant in > winter?) so there are obviously some varieties that take the cold. It is extremely cold hardy, as is Typhonium roxburghii (formerly T. diveracatum).
