How to Care for Anise Hyssop


The anise hyssop (Agastache foeniculum) is a tall perennial herb related to the mint family that has a pleasing licorice scent. It can reach heights of 4 feet and features tall spikes covered with tiny purple flowers. Anise hyssops are especially loved by gardeners for their ease of care and are frequently used in recipes or grown as striking ornamental plants. Butterflies, bees and birds are huge fans of their flowers.

Step 1

Place your anise hyssop in a location where it will receive full sunlight. It should receive a minimum of six hours of sunlight per day and will thrive if it is exposed to a full eight hours of sunlight each day.

Step 2

Make sure the soil around your anise hyssop does not contain standing water. If the soil becomes waterlogged, the plant will develop root rot and die. Mix peat moss into the soil to help it drain better if the ground appears waterlogged.

Step 3

Water only when the soil dries out. The anise hyssop is an excellent plant for the drier areas of your garden and can even tolerate periods of drought.

Step 4

Maintain a 1-inch layer of organic mulch around your anise hyssop. This will provide the plant with nutrients and inhibit weed growth, which can be a problem with these plants.

Step 5

Clip the blooms frequently. (The blooms make excellent cut flowers.) This will encourage the plant to continue blooming. Remove spent blooms as well.
