Plains evening primrose is a low-growing annual wildflower that produces bright yellow blooms from late spring through summer. This compact native plant thrives in sunny, dry conditions and requires minimal water once established. The flowers typically open in the evening, creating a charming display during summer months.
In an HOA neighborhood

Works well in: backyard only.
