Which EEs are winter-hardy in z7?

I'm working on a trade of some of my ears for mini hostas. My trading partner asked me for ears that will come through a z7 Georgia winter. I have a pretty wide collection of Alocasias, Colocasias and a few Xanthosomas, but I bring them all in for the winter, so I really don't know what to propose.

Here are the ones I am pretty sure will come through, but the really common ones won't be much of a trade for special hostas:

Alocasia macrorrhiza "Upright"
A. gageana
Colocasia esculenta -- classic green EE
C. antiquorum illustris
C. Black Magic
C. fontanesi "Black Stem"
C. violacea "Violet Stem"

Any other ideas? Feel free to suggest uncommon ones -- if I don't have them, I might be able to get them...

I'm open to other trades if anyone is interested.

I used to live in Heflin Ala and they over wintered very well there so you should be fine.

here is what has come back for me-
colocasias: red stemmed, Royal Hilo, fontanesi -black stemmed, esculenta, illustris, black magic and black ruffles ( I have Nancy's Revenge and New Guinea Gold in the ground now and am going to leave there over the winter)

Alocasias: California (gageana), Persian palm (calidora), am also going to leave my Sarian in the ground over the winter in a protected spot.

Thanks LavinaMae and tigerlily -- That is helpful. tigerlily, you have some I don't have; I'll D-mail you.

I'm still interested in anyone else's suggestions or experiences with z7 winter-hardy taros.
