Common Questions

White Baptisia questions

What zones can White Baptisia grow in?

White Baptisia 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 White Baptisia deer resistant?

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

When does White Baptisia bloom?

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

Does White Baptisia need full sun?

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

Is White Baptisia drought tolerant?
