Agastache 'Blue Fortune'
Common name: Hyssop-Anise.
Zones 4 to 9.
Plants reach 24 to 36 inches tall and 18 to 24 inches wide.
Growth rate: Moderate, Easy to grow.
A woody-based perennial of the mint family, this giant hyssop cultivar features tiny, tube-shaped, lavender-blue flowers tightly packed in rounded bottlebrush-like spikes atop stiff square stems typically growing to 3 feet tall. Flowers bloom from midsummer to early fall and are attractive to butterflies and hummingbirds.
While easily grown in average, medium, well-drained soils in full sun to part shade, Agastache is best planted in full sun and slightly alkaline soil. Lanky growth may occur in too much shade. The most critical factor is good drainage. This plant will NOT tolerate wet soil, especially in winter. When planting in questionable drainage areas, place a thick layer of gravel in the bottom of the hole and then mix more in with the filler soil. Native to the southwest US and Mexico, it is naturally heat and drought tolerant.
