Agastache 'Black Adder' (Hyssop)

Agastache 'Black Adder'

Hyssop

The second fantastic Agastache given to us by Coen Jansen, 'Black Adder' boasts numerous bottlebrush flowers of vivid blue from mid summer to frost on a compact, rounded plant. It has been hardy for us in the ground and in containers and has proven to be a reliable production plant as well. An early pinch keeps it more compact in pots.
