Aroids in the garden

From: Bob Riffle <71270.3070 at compuserve.com> on 1998.06.23 at 14:17:48(2356) Alocasia macrorrhiza will not survive your winter temps. It's iffy in zone 9, as far as coming back from a freeze, and is really a zone 10-11 subject, although I've seen some recover from the low 20s; but that was in a climate that has very few freezes compared to zone 6. You could try cutting off the leaves after the first light frost and then mulch the root/trunk very heavily with leaves and a covering of some sort (canvas/tarp), but I've got a feeling it will die if kept in that condition for consecutive months. Let us know if you try it as a permanent outdoor subject.
