While most Agastache (Anise Hyssop) come from the American Southwest and Northern Mexico, this hails from Korea, Japan and China. Butterflies, honeybees and hummingbirds love it. Flowers of deep blue-purple arise from dark green, wrinkly foliage from summer to fall. The leaves of these bushy perennials are a fragrant aroma of licorice, mint and citrus. Heronswood Mist is taller than the original Asian species Agastache rugosa, which was collected in Korea in the late 20th century by plant explorer Dan Hinkley, founder and former owner of Washington state’s Heronswood Nursery. It grows well in USDA Zones 7 to 9. Heronswood Mist works well as a short screen. However, it is also excellent in sunny patio containers. Heat tolerant and drought resistant, it thrives in dry gardens. Similar to so many members of the mint family, it likes good drainage.
Native pollinators love it.
