Summary

Agastache foeniculum, commonly known as Anise Hyssop, is a perennial herb that can be deciduous or semi-deciduous depending on the climate. It is native to open woodlands, grasslands, and prairies in the Central and Intermountain USA and Canada. Anise Hyssop typically grows 2 to 4 feet (61 to 120 cm) tall and about 1 foot (30 cm) wide, forming a clump-like, upright shape. Its leaves are oval and toothed with a whitish underside, and it produces showy verticillasters of bright lavender flowers from June to September, which become more colorful near the tip. One plant can produce upwards of 90,000 individual flowers, and the root system is characterized by a taproot.

Anise Hyssop is highly valued for its ability to attract a wide range of pollinators, including hummingbirds, butterflies, and various bees, making it an excellent choice for pollinator gardens. It is also deer and drought-tolerant, adding to its appeal for gardeners. This plant is commonly used in borders, herb gardens, and as a fragrant addition to cut flower arrangements. It thrives in full sun to part shade and prefers soils with slow to medium drainage. While it can tolerate low to medium water conditions, it benefits from regular watering during prolonged dry spells. Anise Hyssop is not typically associated with serious diseases or pests, but powdery mildew can occur in humid conditions.CC BY-SA 4.0
