'Blue Fortune' Bill Williams Mountain giant hyssop (Agastache 'Blue Fortune') is a perennial for borders, pollinator gardens, cottage gardens, and meadows. It is hardy to USDA zone 5, or down to -20°F (-29°C). This plant likes full sun and dry to moist soil of most types. Its fragrant gray-green leaves and purple flower spikes draw butterflies, hummingbirds, and bees. It blooms in early to late summer and again in early to late autumn. Deer and rabbits tend to browse other plants first.
