Common Questions
Anise Hyssop questions
What zones can Anise Hyssop grow in?
Anise Hyssop is hardy in USDA Zones 4–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

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.
