Common Questions

Wallflower questions

What zones can Wallflower grow in?

Wallflower is hardy in USDA Zones 5–8. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Wallflower deer resistant?

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

When does Wallflower bloom?

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

Does Wallflower need full sun?

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

Is Wallflower drought tolerant?

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