Seabeach evening primrose is a low-growing native perennial that forms spreading mats of small leaves close to the ground. It produces bright yellow, four-petaled flowers that open in the evening throughout most of the growing season, creating cheerful color from spring through fall.

In an HOA neighborhood

Seabeach 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.

  • Low, spreading growth habit may appear weedy or unkempt
  • Ground-hugging form doesn't fit typical landscaping expectations
