Common Questions

Common Rosemary questions

What zones can Common Rosemary grow in?

Common Rosemary 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 Common Rosemary deer resistant?

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

When does Common Rosemary bloom?

Common Rosemary typically blooms in late spring through early summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Common Rosemary need full sun?

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

Is Common Rosemary drought tolerant?

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