The common forms sold at most retail markets is a large strong grower and it can survive in zone 6 if well protected usually up against the foundation of a house or in a sheltered area. I am guessing your compost heap produced enough decomposing heat during the winter it did not freeze solid. Their are other forms that I have had very good luck with over wintering here in Zone 6 here are a list of the ones that have survived here with info on them.

Colocasia pink china zone 6 for 11 years the last 7 years no mulching. Almost a weed
Colocasia black Pearl 5 years usually mulched 2 years no mulch survives very well
Colocasia Gigantea common form. I recommend mulching this one each year it survives very well tons return for 8 years
Colocasia Big dipper 8 years I always recommend mulching this one. If I don't mulch a few usually return but their is a large loss.
Colocasia Dark star 1 year has returned very well. Still testing it.
