Flowers – Agastache – Heirloom Seeds

What is Agastache Plant

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 (0.5 to 2 m.) 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 (7.5 to 10 cm.) 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.

How to Grow Agastache

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. Most plants can survive temperatures down to -12 C. if heavily mulched. Provide plenty of water when the plants are establishing, but they can mostly fend for themselves thereafter.

Agastache Uses

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. Growing Agastache in the butterfly garden not only attracts those beautiful insects, but pollinators and hummingbirds.
