Black Adder Hyssop
Lovers of heat, these tough and drought resistant Mint family relatives guarantee terminal spikes adorned with brightly colored, tubular flowers just about all summer long. Agastaches are easily grown in well drained soils, and will bloom more profusely, over an even longer period of time, if the flowering stems are cut back in midseason.
A nectar-rich magnet for hummingbirds and butterflies, long racemes of vivid blue-violet flowers unfurl from darker purple buds. Medium green foliage and straight stems support the bottlebrush-like blooms from midsummer until frost. This splendid new introduction between A. rugosum and A. foeniculum brings late season oomph and a vertical element to the mixed border or to a favored pot, while wafting a delicious licorice smell and resisting those pesky deer..
Size: 2' 0" – 2-1/2' high x 18" wide.
