Black Adder Hyssop

Agastache ‘Black Adder’

Agastache

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 soil, and will bloom more profusely, over an even longer period of time, if the flowering stems are cut back midseason.

AVAILABLE MID-JUNE 2021

<i>Agastache</i> x ‘Black Adder’

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 Agastache rugosum and Agastache foeniculum brings late season oomph and a vertical element to the mixed border or to a favored pot, while wafting a delicious licorice aroma and resisting those pesky deer.

Blooms June–September

Size: 2' 0" – 3' 0" high x 18" wide.

Hardy to zone 6.
