Common Questions

Bristly Phlomis questions

What zones can Bristly Phlomis grow in?

Bristly Phlomis is hardy in USDA Zones 6–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Bristly Phlomis deer resistant?

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

When does Bristly Phlomis bloom?

Bristly Phlomis 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 Bristly Phlomis need full sun?

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

Is Bristly Phlomis drought tolerant?

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