Tom -- I did notice that Impressionist really took a long time to settle in here -- and then after moving it, and after last winter/spring -- it died. Debra sent me a couple of little rhizomes on the off-chance they would make it here -- so apparently she had trouble with it too (in Texas).
This isn't indicative of all of Joe Ghio's Irises that I have here -- but that one for sure is very finicky.
I love his Irises too! Hope the newer ones do better for all of us!!
