    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.) seeking nectar or pollen. The flowers are also visited by an oligolectic bee, Doufourea monardae. 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.

    "Agastache foeniculum, commonly called anise hyssop, is a species of perennial plant in the mint family, (Lamiaceae). This plant is native to much of north-central and northern North America.

    Anise hyssop is in the same family as hyssop (the mint family Lamiaceae), but they are not closely related. Hyssop (Hyssopus) is a genus of about 10-12 species of herbaceous or semi-woody plants native from the east Mediterranean to central Asia.

    Anise hyssop was used medicinally by Native Americans for cough, fevers, wounds, diarrhea. The soft, anise-scented leaves are used as a seasoning, as a tea, and in potpourri. The purple flower spike is favored by bees who make a light fragrant honey from the nectar."

    Agastache foeniculum has special value to native, bumble, and honey bees, and attracts a variety of bee species including longhorned, bumble, small resin, and leafcutter bees.

    This plant also plays a beneficial role in the garden by attracting predatory insects such as bee flies and soldier beetles. These beneficial insects feed on a variety of common garden pests.

    The name of "Agastache" for this perennial of the Mint Family comes from Greek meaning "many spikes" and "foeniculum" comes from Latin for "hay." This species has a large native range of all of southern Canada into the Northwest Territory, some of New England & New York down into Kentucky through Illinois to Colorado, Wyoming, Montana, & Washington. This is a very easy upright plant for sunny, well-drained soils. It has a small taproot and some spreading rhizomes. It can be divided in spring or fall, but I think this is one of the perennials that can be left alone. The purple flower spikes are about 3 to 6 inches long and do not have a scent, but are very attractive to many kinds of bees and to flies, butterflies, moths, and an occasional hummingbird. It blooms about 2 months and the bloom can be extended some by dead-heading. The crushed leaves have an anise scent and can be used to make a tea. It is sold by most native plant nurseries and by many conventional nurseries also. There are several cultivars. My neighbour across the street has had two of them for about 15 years and they keep doing well.
