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.

Agastache 'Black Adder' Growing and Maintenance Tips

Grow in full sun and average to dry soils with average to good drainage. Definitely more tolerant of winter wetness than its pink cousins, but it may still succumb to wet clay soils in the winter.
