Notes
'Red Happiness' Bill Williams Mountain giant hyssop (Agastache 'Red Happiness') is a perennial for borders, pollinator gardens, and cottage gardens. It is hardy to USDA zone 5, or down to -20°F (-29°C). This plant likes full sun and dry to average, sandy or loamy soil. Coral-red flowers open from early to late summer and again in early autumn, and butterflies, hummingbirds, bees, and birds visit the blooms. It sits low on the menu for deer and rabbits. It also tolerates drought once settled in.
Pairs well with Blanket flower, Little bluestem, and Feather reed grass.
