White-stem evening-primrose is a low-growing annual wildflower that produces bright white or pale pink flowers from late spring through summer. The blooms open in the evening and stay open through the next morning, creating a charming display in sunny, dry areas. This drought-tolerant native requires minimal care once established.
In an HOA neighborhood
White-stem Evening-primrose takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Annual lifespan creates gaps in plantings

Wildlife value
