Frequently Asked Questions

Why won't my Cape Primrose bloom continuously like it's supposed to?

Consistent blooming needs 12–14 hours of bright indirect light daily. Insufficient light is the most common reason flowering slows or stalls, so consider a grow light in darker months.

Why do my Cape Primrose leaves get spots when I water them?

Water landing on the textured leaves and sitting in the light can cause leaf-spotting. Always water at the soil level rather than overhead, similar to care for African Violets.
