  Re: [Aroid-l] Cold Tolerant Amporhs

I am also in zone 6 (NW Arkansas) though we used to periodically see -28 C
(-20 F) as overnight lows. The only Amorph that has proven itself through
the worst this climate has to give is A. konjac. I gave some to a friend
at the Denver BG and they have survived for 5 or 6 years there now also.

The only other species I have outdoors is a plant of A. bulbifer, which
has now survived for I think 3 years (I'd have to check the records) with
no special treatment. We have not seen anything below -18 C (0 F) for
about 9 years now, but it did come through the horrible ice storm in
January of this year with no problem. I know from experience with other
plants that some things that tolerate cold well will not tolerate a layer
of ice on the ground for days slowly melting, so that gives me hope for
long-term hardiness here.
