Love Ava! I have 3 growing next to each other in the back yard and during late Summer, I noticed they were just as colorful and fresh looking as early Summer. The colors don't fade.
It's the best selling Agastache at High Country Gardens, according to their printed catalog and has been since they introduced it in 2005.

I'm getting another Ava this year, making 4 plants I'll have. I did plant Ava a few years before, but lost them for one reason or another.
Gorgeous Agastache!
