Growing notes
- Plant in sunny herbaceous borders and pollinator gardens — bees and butterflies cover the flower spikes throughout summer
- Edible leaves — anise-flavoured, dried for tea, fresh in salads, added to fruit dishes
- Self-seeds freely where conditions suit and tolerates dry soils
- Distinct from culinary hyssop (Hyssopus officinalis, already in the database) — Agastache is a different genus with anise rather than bitter-herbal flavour
