'Blue Boa' Anise Hyssop is an improvement on 'Blue Fortune'.  The large fragrant flower spikes are larger and deeper blue in color, verging on violet.  The foliage is a bright green and wonderfully fragrant when touched.  Agastache x 'Blue Boa' blooms for a prolonged time in mid to late summer, especially when deadheaded after the initial flowers flush.  Although 'Blue Boa' Hyssop has proven itself to be very cold tolerant, it needs excellent drainage to survive our winters.  Introduced by Terra Nova, and winner of a number of Horticultural Awards.
