Anise Hyssop Growing and Maintenance Tips

Grows best in full sun and an average to dry, well-drained soil. If desired, pinch main stems in June just before buds form, to maintain a compact habit. Remove finished flowers to promote a second flowering. No serious pest or disease problems. Spreads by rhizomes and will easily self-seed in optimum conditions.
