Agastache foeniculum – Anise hyssop

Agastache foeniculum – Anise hyssop

“Planted in full or partial sun and mesic to dry conditions, this perennial grows 3 to 5 feet tall and is planted 12 to 24 inches apart in well-drained soil. The foliage has an anise or licorice scent and can be used as a flavoring in salads and teas. Seeds can be used in cookies cakes and muffins. The upper stems terminate in spikes of flowers that can come in many colors about 3-6″ long. The small flowers are arranged in dense whorls that are crowded along the spike and the flowers are replaced by smooth, oval-shaped nutlets. Flowering starts, even in unfavorable summers, in late July and continues until late autumn. The plants will self-seed in the garden and usually overwinter well if the soil is well-drained. Anise hyssop will attract bees, butterflies and/or birds to the garden. If you decide to propagate this plant, division can be done in spring or fall.” (North Carolina Extension)

Product Description


Agastache Foeniculum Botany by Dr. John Hilty

Mint family (Lamiaceae)

1482 original - Agastache foeniculum - Anise hyssop


“The preference is full or partial sun, and mesic to dry conditions. The soil can consist of loam, clay-loam, or contain some rocky material. Foliar disease isn’t a significant problem, although some of the lower leaves may drop from the central stem in response to a drought. Occasionally, slugs and insects will feed on the leaves, creating holes. This member of the Mint family is more resistant to drought than many others.” (Hilty)

Faunal Associations:

“The flowers are cross-pollinated primarily by honeybees, bumblebees, digger bees (Melissodes spp.), leaf-cutting bees (Megachile spp.), Halictid bees (Lasioglossum spp., etc.), and Masked bees (Hylaeus spp.), which seek nectar or pollen. The flowers are also visited by an oligolectic bee, Dufourea monardae, which has extended its range into Illinois. Other occasional floral visitors are Syrphid flies, bee flies, and various butterflies, skippers, and moths. Mammalian herbivores normally avoid consumption of this plant as the anise scent of the foliage is repugnant to them. The anise scent may also deter some leaf-chewing insect species.” (Hilty)
