hardiness

From: Lester Kallus <lkallus at earthlink.net> on 1997.02.19 at 16:58:37(391) I'm curious if my plants will have survived the winter. Yesterday, while searching through another catalog, I found Colocasia esculenta listed as a zone 9 plant. Having thought it was a zone 7 plant, I left mine out this winter. +More This past winter here on Long Island has been a warm one. Although usually a zone 7a area, we had a balmy 8a with two short-lived (4-5 hours) dips into 7b. Are my Colocasias doomed? How about my Amorphophallus bulbifer? I'm curious because it's still not too late to order a replacement if the ones I left outside are doomed. Les

Mine are planted in sandy loam within sight of the Chesapeake Bay, 7b/8a usually but balmy this year. Mine have wintered over through two winters, this last the milder of them. The top of the large corm became a bit mushy from frost damage, but the plant performed beautifully anyway, as did two smaller corms. I have not tried overwintering my bulbifer (waiting until my leaf-corm provides me with a spare). Clear skies, Al

Realize that most of the writing about aroids was not done by gardeners in zone 7.

True for hardiness, but also other growing conditions. I am in zone 6b (less than 2 miles N of USDA research station in Beltsville) --> no error in the zoning. Among those that are not supposed to live here: I cover laurel with dead stems of Aster and the laurel survives very short. I do nothing special to Dahlia and Zantedeschia. After 8 years the dahlia crowd is down to 5, but the Zantedeschia cultivars are slowly multiplying in all-morning sun. Clematis armandii is reduced to a non-blooming erect herb (winter) vining a bit in summer. Passiflora caerulea has vigorous non-blooming climbing stems. But on the other hand, I can't keep Pinus bungeana, Corydalis flexuosa ... through winter. And it should not be the cold.
