Comment:

Planted in full or partial sun, and mesic to dry conditions this perennial grows 3 to 5 foot tall and is planted 2 to 24 inch apart in well drained soil.  The foliage has an anise or licorice scent and can be used as flavoring in salads and teas.  Seeds can be used in cookies cakes and muffins.  The upper stems terminate in spikes of flowers which can come in many colors about 3-6" long. The small flowers are arranged in dense whorls that are crowded along the spike; 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.  Anise hyssop will attract bees, butterflies and/or birds to the garden.

No serious insect or disease problems. Crown/root rot may develop in poorly drained soils. Watch for rust, powdery mildew and leaf spots.
