Blue Fortune Hyssop

Agastache ‘Blue Fortune’ · a blue anise hyssop

A long-blooming hyssop with lavender-blue spikes from midsummer into fall that bees and butterflies crowd, over leaves with a licorice-mint scent. It shrugs off heat and dry spells and handles humidity better than many hyssops. The one must is sharp drainage: wet or heavy clay soil, above all in winter, rots the crown.

Spacing

VeraScape spaces plants so their grown canopies just touch. For Blue Fortune Hyssop, that’s about 1.5 ft apart, center to center.
