Agastache (Agastache spp.)
Agastache Plant FeaturesAgastache, also called hyssop, may be hard to pronounce, but it's sure easy to grow! Once established, this rugged, sun-loving perennial blooms its head off throughout the summer, even during periods of heat and drought. Its colorful, nectar-rich flowers are also a favorite with hummingbirds and butterflies. Plus, they come in dwarf and standard forms. Dwarf agastache varieties grow just 2 feet tall while standard-sized varieties can stretch up to 4 feet high or more. Flower colors include violet, purple, pink, red, orange, yellow, and white. The pretty gray-green foliage typically has a strong minty scent when brushed or rubbed. And to top it all off, the plants are also rabbit- and deer-resistant. Hardy to zones 5-9.

Agastache Growing InstructionsAgastache grows best in full sun and well-drained soil. Because it is so drought tolerant, it thrives where many other perennials fail. Cutting the faded flowers off the plant will help keep it blooming more profusely, and prevent some varieties from setting seed and spreading in the garden. In late autumn, after killing frost, you can cut the plant back to the ground for a clean, tidy garden -- or leave it standing for winter interest and to provide a food source for birds, which will feast on its seeds.
Good drainage is essential to keep agastache healthy. The plants do not like wet feet and won't thrive in damp, heavy clay soil so be sure to improve the flower bed with plenty of organic matter before you plant.
Note: Agastache is not intended for human or animal consumption.
