Anise Hyssop (Agastache foeniculum) is a perennial subshrub or herb native to the central and northern parts of North America, including Alberta, British Columbia, Colorado, Idaho, Illinois, Iowa, Manitoba, Minnesota, Montana, Nebraska, New Brunswick, North Dakota, Northwest Territories, Ontario, Québec, Saskatchewan, South Dakota, Washington, Wisconsin, and Wyoming. This plant thrives in full sun with well-drained soil that can be light (sandy) or medium, growing up to 120 cm tall and spreading about 50 cm wide. Anise Hyssop is valued for its ornamental value and traditional uses, making it a suitable addition to gardens where space is limited. The plant's edible flowers and leaves have been used traditionally to aid in nervous indigestion and promote better sleep due to its mint-family aromatic properties. Anise Hyssop can tolerate dry to moist conditions but dislikes standing water. Hardy from zones 4-10, this perennial subshrub grows up to 120 cm tall with a spread of about 50 cm. For best results, space plants 30 cm apart. Harvest its edible leaves and flowers for culinary use. While Anise Hyssop is not recommended for medicinal treatment or consumption without professional guidance, it can be enjoyed in teas and as an ornamental plant in gardens native to its range.
