Agastache 'Purple Haze'

hyssop

This decidedly hardy Agastache displays long racemes of smoky blue violet flowers that never seem to stop coming. It remains compact in a container with an early pinch and is in flower from July to frost. It has survived wet and dry, warm and cold winters in Pennsylvania where it has been in the ground since Spring 2000. Hardiness beyond zone 6 is unknown.
