Last year I bought a elephant ear from a small nursery. I have grown alocasia for years from bulbs. I left this plant in a pot to overwinter as I have done before. We had more snow than usual but the temp was a normal winter. We live in zone 7a-b. The plant didn't live so I thought the roots must have froze too much in the pot. I bought more elephant ears today but the gentleman mentioned these were tissue grafted plants....... Does that make a difference how the plant overwinters?
I don't know alot about the plant you describe but the rootstock is usually more hardy and of course in the ground protected but grafts die sometimes just because of compatability but winter kill is usually related to zone hardiness not the graft.

I do quite a bit of fruit tree grafting, if I read your question right I'm thinking you have a plant that is a plant tissue clonal specimen. If that's the case, then it's as winter hardy as the original plant the tissue came from.
