Anise hyssop is the bee bar with licorice perfume — spikes of purple-blue flowers, edible leaves for tea, and none of the corporate ‘wellness blend’ packaging. Tougher than it looks in heat if soil drains; in subtropical and tropical Americas give it airflow and avoid boggy stagnation. Self-seeds politely compared to true mint, but still check volunteers. Full sun to light shade. Moderate moisture; drought-tolerant once established but blooms harder with even water. Well-drained loam; mulch roots in summer. Seeds: surface sow; light-dependent germination. Division in spring or fall. Softwood cuttings. Snip leaves for tea before flowering for sweetest aroma. Leave late flowers for pollinators if you are not greedy.
