Hyssopus officinalis aristatus

A tier

Hyssopus officinalis aristatus (often treated as a subspecies or variety) is the aristate rock hyssop—bristly floral details, compact habit, and intense flowering on short plants. Botanically closer to true hyssop than to Agastache giant hyssops. Leaf oils remain in the bitter-mint camphor family suitable for careful cookery and herbal use. Specialty nurseries supply aristatus for alpine houses and troughs. Culinary pinches work when you need authentic Hyssopus character from a small plant. Label with the full name to avoid mix-ups with unrelated “rock herbs.”
