Hyssop

♦ Zones:  6 - 9     Height:  24 - 36"     Exposure:  Full Sun to Part Shade ♦

'Black Adder' is an upright, clump-forming giant hyssop that grows to 2-3' tall. It is a hybrid resulting from a cross between A. rugosum and A. foeniculum. It is noted for its long summer-to-frost floral display of tubular, 2-lipped, smoky red-violet flowers that bloom in showy, bottle-brush, terminal spikes (to 6-8" long). Flowers appear in many-flowered verticillasters (false whorls) which are densely packed to form the flower spikes. Flowers emerge from nearly black buds. Aromatic (anise/licorice scented), lance-shaped to ovate leaves are blue green. Flowers are attractive to bees, hummingbirds and butterflies. Agastache comes from the Greek words for “much” (agan) and “grain stalk” (stachys) in reference to the flower spikes.
