Agastache 'Black Adder'

Giant Hyssop

Plant Type: Perennial

This variety of Agastache is a sterile hybrid that produces gorgeous, tall bottle-brush spikes lined with tiny red-purple flowers that are adored by bees, butterflies, hummingbirds and other beneficial pollinators. The long lasting flowers bloom from mid to late summer and into the fall and have a pleasant anise scent. It looks fantastic when planted in prairies, meadows, mass plantings, or dotted throughout borders. It requires full sun for the best floral show and average, dry to medium soil. Once established, it is tolerant of heat and drought and is deer and rabbit resistant!
