Agastache is a genus of aromatic flowering herbaceous perennial plants in the family Lamiaceae. It contains 22 species, mainly native to North America, one species native to eastern Asia.
Agastache is in the Hyssop family of herbs and makes a flavorful tea. It is a striking plant that has many varieties, some of which are hardy and others that are frost tender and grown as annuals in most cooler climates. Growing Agastache requires sun and well drained soil. The leaves resemble catmint and are a dull green with heavy veining. The plants can grow 2 to 6 feet tall and produce the showy Agastache flowers until the first frost. Agastache flowers come in a variety of colors and rise up off of stiff triangular stems. The blooms have the appearance of being coated with fuzz because they are comprised of many tiny florets. The entire flower may be 3 to 4 inches long and begin to bloom from the top down. This means that the florets at the crown of the flower die out first, leaving tips that look slightly burnt. This just adds more interest to the Agastache plant.
