I have terrible luck with iris.

I couldn't give them away so I tried to rehome them myself. Makes me think of the poster irisblue when they bloom.

I have amazing iris. I planted two kinds (no idea which) in a narrow edge of a swale, between the bottom of the swale and the neighbor's pseudo rock one foot high wall. Several times a summer the swale fills with water for an hour or so. They grow like gangbusters. I never do anything for them. I think this is an accidental occurrence of the perfect microclimate for them.

but what a welcome surprise. Irises are gorgeous.

It's so warm they must be confused.
