What makes Blue Fortune Anise Hyssop (Agastache) better than other cultivars?
This new cultivar from Rotterdam, Holland is a cross between two species. It has the abundant purplish-blue flower spikes, 3 ft height, and long mid-summer bloom of its foeniculum parent (US native), and the hardiness at least to USDA zone 4 of its rugosa parent (Asian native)–so truly the best of both worlds!
