Spikes of tubular, smokey-lilac flowers open from dark purple buds for a striking effect. The licorice-scented foliage is edible and good in salads. Excellent planted en masse in the perennial border or in the herb garden. Drought tolerant once established. Blooms from summer until frost. A hybrid between the North American A. foeniculum and the Asian A. rugosa. Deadhead spent flowers to promote additional bloom.
