This one has tempted me since it came on the market. Keep us updated. In recent years I have gotten away from experimenting with Agastache. These days I am sticking with the ones that are tried and true: a bunch of 10 year rupestris and hybrid of it like Firebird and random seedlings that have survived. I also like several eastern natives, the short-lived but freely volunteering foeniculum and a white-flowered version of scrophulariifolia. There are probably a few hybrids with cana and aurantiaca in them but that was generations ago. Still, Blue Boa is tempting.
