A tender perennial with aromatic leaves and colorful flower spikes all summer long. While traditional varieties have blue or purple colored flowers, newer varieties feature bold colors such as red and orange. In warm climates, it comes back consistently each year. In cold climates is self-sows readily making it an annual addition to your garden. The flowers are attractive to hummingbirds, butterflies and bees, while the anise-flavored leaves can be used in teas and cooking.
Plant in spring after all danger of frost has passed. You can plant any time until early summer. Fall planting will stay dormant all winter and sprout at the appropriate time in spring.
Light: Grows and flowers best in full sun. They will survive part shade, especially afternoon shade in warmer climates, but may not flower as well.
Soil: Grows best on fertile, well-drained soils. It likes a soil close to neutral and in areas with acidic soils will benefit from the addition of lime.
Spacing: 4 to 6 weeks before a last frost date. Move plants outdoors when the transplants are at least 4 inches tall. Space plants 12 to 15 inches apart. You can also plant outdoor in rows, thinning to 1 foot apart after 4 leaves form.
Watering: Agastache is a drought-tolerant herb, especially once established. Keep the soil moist for germination and seedling growth. Once mature, these mint family plants are tough and can go weeks without watering.
Fertilizer: Amend the soil before planting with compost. Additional fertilizer usually isn’t needed. In fact, too much fertility will cause the plant to flower less and later, and reduce the essential oils in the leaves and flowers. It also can cause the stems to become floppy and fall over more easily.
Pruning: Trim back plants by pinching the new growth in spring to promote bushier growth. Deadhead (trim) spent flower stalks to keep the plant tidy. If growing as a perennial, don’t prune or deadhead past midsummer. Pruning too late in the season will stimulate new growth in fall that may not survive the winter.
Growing Agastache can be done indoors as starts, or you may directly plant seeds into the garden in spring. Flowers will be produced more quickly on plants that are started indoors in May and transplanted in early summer. The Agastache plant is hardy in USDA plant hardiness zones 4 to 10. Most plants can survive temperatures down to 10 F. (-12 C.) if heavily mulched.
Provide plenty of water when the plants are establishing, but they can mostly fend for themselves thereafter.
Agastache are usually tall plants and their lengthy stalks show best at the back of a perennial border or lining a fence. They can be used in container gardens or in cut flower gardens, as the Agastache flowers are long lasting.
