Common Questions

False Indigo questions

What zones can False Indigo grow in?

False Indigo 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 False Indigo deer resistant?

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

When does False Indigo bloom?

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

Does False Indigo need full sun?

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

Is False Indigo drought tolerant?

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