Anise Hyssop, Blue Giant Hyssop
Blue giant hyssop is a strongly aromatic, drought tolerant, erect perennial native throughout the northern United States and Canada. This member of the mint family has downy, medium green, licorice-scented leaves that appear on long stems topped with spikes of blue-purple flowers that appear from from midsummer to autumn. Highly attractive to bees and butterflies, this plant will continue blooming if deadheaded. The fuzzy leaves that release the licorice aroma tend to dissuade browsing damage from deer.
Blue giant hyssop is tolerant of poor soils and an excellent choice for sunny mixed borders and informal wildflower gardens. It can also be dried and used to make herbal tea.
