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.
