Common Questions

Red Valerian questions

What zones can Red Valerian grow in?

Red Valerian is hardy in USDA Zones 5–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Red Valerian deer resistant?

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

When does Red Valerian bloom?

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

Does Red Valerian need full sun?

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

Is Red Valerian drought tolerant?

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