Common Questions

Butterfly Bush questions

What zones can Butterfly Bush grow in?

Butterfly Bush 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 Butterfly Bush deer resistant?

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

When does Butterfly Bush bloom?

Butterfly Bush typically blooms in mid-summer to fall through early fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Butterfly Bush need full sun?

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

Is Butterfly Bush drought tolerant?

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