Re: Hardiness of Species Irises

---

The only iris that has died from cold in my garden is I. confusa
(SIGNA 038257 H.P. ex Tian Quan Co Sichuan) last year.

A friend reports the temperature was -12C. I was away, so don't know
what the conditions were like in my garden, or for how long.

I. japonica was not harmed.
