Anise Hyssop

Native Wildflower

Anise hyssop is a native perennial with upright spikes of lavender to purple flowers and a long summer bloom period. It combines well with prairie flowers and ornamental grasses in sunny, well-drained gardens.

Why plant it

This plant is especially useful for extending color and pollinator activity through much of the summer. Its vertical flower spikes add contrast and rhythm to mixed borders and habitat-focused plantings.

How to grow it

Grow anise hyssop in full sun and well-drained soil. It tolerates average garden soil and handles short dry periods once established, but it does not like persistently soggy ground. Water regularly during the first growing season, then reduce irrigation to as needed. It is generally hardy in USDA Zones 4 through 8.

Wildlife it supports

Bees, butterflies, and other pollinators are frequent visitors to the flowers. The extended bloom period makes it a useful nectar source across much of the growing season.

Tips

Avoid crowding plants so foliage and stems dry quickly after rain or dew. Leaving some flower spikes standing can add structure and may allow light self-sowing in favorable conditions.
