Re: arisaema candidissimum

---

We have gotten temps from 7-17* F the last couple of winters, I did have 4 calla lillies to come back which surprised me. I forgot to dig them up.

 

 

 

 

 

It should be perfectly hardy there - it is here in NW Arkansas, also zone
6b but with occasional lower temperatures.

However, here many of the Asian arisaemas seem to "fail to thrive" and
disappear over the course of several years. They come back each year, but
with less vigor, until some year they don't show up at all. I don't know
for sure whether this is simply me not siting them correctly, or if there
are diseases here that eventually kill them. (We do have the arisaema rust
in the area, for instance, though I've never seen it on any plant in my
yard.)

I have a couple of tender Asian arisaemas that I grow in pots in the
greenhouse, and by contrast they seem to stay vigorous and increase. (The
only problem with them is they don't ever seem to go dormant, and I owe a
couple of people offsets of them.)
