Hardiness of Japanese irises

Hannibal, NY(Zone 6a)

Hello, Upper Midwest Gardeners,

Over on the iris forum I have a thread going asking if anyone in Z3 or Z4 grows Japanese irises. If any of you do, would you mind coming over, and giving me the following info: Your zone, the approximate amount of snow cover you get in winter, the cultivars of Japanese iris (if you know them), how many you have, and how long you've had them.

Here's the link to the thread.


Thank you so much!
