Stemless Evening Primrose Seeds (Oenothera triloba) Lawn Friendly Ground Cover

A ground-hugging native that hides its great blooms until dusk. Stemless Evening Primrose grows as a flat rosette pressed close to the soil, easy to overlook — until it opens its large, pale yellow flowers that fade to pink as they age, often blooming in the late afternoon and staying open through the night for moth pollinators.

This Primrose is native mostly to Texas and is a Winter annual, growing a rosette early in the year and blooming in Spring

Rosette diameter: 4–8"
Bloom time: Late winter through spring
Flower color: Yellow, aging to pink/rose
Sun: Full sun
Soil: Clay, caliche, poor/compacted soils — thrives where little else will
Water: Low; very drought-tolerant
Zones: 5–9
Habit: Low rosette, taprooted

Because it lies so flat to the ground, it's a great choice for hard-packed clay, disturbed roadside soil, or spots where you want early-season color without any height. Flowers typically open in late afternoon/evening and close by mid-morning — a fun one for anyone who likes watching a garden change through the day.

Fits well in native lawns, rock gardens, and tough-soil areas where you want low color without competing for space.

Germination: Best sown in Fall as this species forms a rosette in Winter and blooms the following Spring
