Common Questions

Hairy Wormwood questions

What zones can Hairy Wormwood grow in?

Hairy Wormwood 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.

Is Hairy Wormwood deer resistant?

Not reliably. Deer may browse Hairy Wormwood, especially tender spring growth — plan on repellents or fencing where pressure is high.

When does Hairy Wormwood bloom?

Hairy Wormwood typically blooms in early fall through late fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Hairy Wormwood need full sun?

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

Is Hairy Wormwood drought tolerant?

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