Agastache plants are easy, undemanding perennials to grow. They prefer sun but tolerate some light shade, and they dislike waterlogged soil, so drainage it very important for good performance. Provide a complete organic fertilizer each spring. Mature plants require a moderate amount of moisture and can dry out in-between waterings. If growing as herb plants, harvest fresh leaves just before blooming for best flavor. If needed, the plants can be divided in the fall. Division will help keep the plant robust and healthy. In areas with very cold winters, a heavy mulch gives extra protection. When different varieties are grown together, cross pollination may occur. Deadheading the spent blooms and removing any volunteers will help prevent cross pollination.
These striking and versatile flowers are also great for cutting. They have lengthy stalks and last well in the vase. Agastache will win anyone’s heart, and because they are known nectar plants, many buzzing and delightful insects will adore them as well!
