Common Questions

African Lily questions

What zones can African Lily grow in?

African Lily is hardy in USDA Zones 7–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is African Lily deer resistant?

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

When does African Lily bloom?

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

Does African Lily need full sun?

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

Is African Lily drought tolerant?

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