Common Questions

Anise Hyssop questions

What zones can Anise Hyssop grow in?

Anise Hyssop is hardy in USDA Zones 5–8. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Anise Hyssop deer resistant?

Yes — Anise Hyssop is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does Anise Hyssop bloom?

Anise Hyssop typically blooms in mid-summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Anise Hyssop need full sun?

Anise Hyssop does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Anise Hyssop drought tolerant?

Yes — once established (usually after the first full season), Anise Hyssop handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
