Oenothera Seed ( Perennial )
The dusk and dawn-blooming flowers attract night-flying moths and early morning bees, making it a valuable plant for pollinator gardens.
Pink Evening Primrose (Oenothera speciosa 'Rosea') is a graceful native perennial celebrated for its delicate satiny pink flowers that seem to carpet the landscape in late spring and early summer. Often called Showy Evening Primrose, Mexican Evening Primrose, or Pink Ladies, this hardy wildflower produces masses of soft blush-pink blooms with golden centers that brighten borders, meadows, rock gardens, and naturalized plantings. The flowers open wide in the cool of the morning and evening, creating a spectacular display that appears to float above the attractive green foliage.
Fast spreading by underground rhizomes, Pink Evening Primrose forms beautiful colonies that provide outstanding ground cover while attracting bees, butterflies, and numerous beneficial pollinators. Plants typically grow 12 to 18 inches tall and bloom for many weeks, making them one of the finest choices for gardeners seeking a carefree perennial that thrives in sunny locations. Once established, this North American native is remarkably drought tolerant and requires very little maintenance.
Garden Uses
Pink Evening Primrose is ideal for cottage gardens, native plant gardens, wildflower meadows, pollinator gardens, prairie plantings, rock gardens, slopes, borders, roadside plantings, and naturalized areas. Its spreading habit makes it especially useful as a flowering ground cover in sunny locations.
The soft pink flowers combine beautifully with purple coneflowers, black-eyed Susans, gaillardia, lavender, yarrow, coreopsis, ornamental grasses, salvia, liatris, and other drought-tolerant native perennials. The blooms also make delicate additions to fresh-cut wildflower bouquets.
Growing Information
Pink Evening Primrose thrives in full sun but will tolerate light partial shade. It grows well in average, sandy, rocky, or moderately fertile soils provided drainage is good. Mature plants generally reach 12 to 18 inches tall while spreading 18 to 36 inches or more through underground rhizomes.
Sow seeds directly outdoors in spring or fall, or start indoors 6 to 8 weeks before transplanting. Cover seeds lightly with soil and maintain even moisture until germination, which typically occurs within 10 to 21 days. Plants establish quickly and may bloom during their first growing season under favorable conditions.
Once established, very little care is required. Water occasionally during prolonged drought, although mature plants tolerate dry conditions exceptionally well. Colonies may be divided every few years if spreading becomes excessive or if new plants are desired.

Evening Primrose (Oenothera) is a diverse group of hardy flowering plants admired for their delicate cup-shaped blossoms, exceptional adaptability, and outstanding value to pollinators. Many species produce large, satiny flowers that open dramatically in the evening, giving rise to the common name "Evening Primrose." Depending on the species, blooms may be bright yellow, white, pink, or soft blush, often glowing in the fading light and attracting night-flying moths as well as daytime bees and butterflies. These beautiful wildflowers have become favorites in cottage gardens, native landscapes, prairie plantings, and water-wise gardens around the world.
Most perennial evening primroses form attractive clumps or spreading colonies, blooming from late spring through summer with hundreds of cheerful flowers. Their remarkable drought tolerance, adaptability to poor soils, and long flowering period make them excellent choices for low-maintenance gardens. Whether planted in formal borders or allowed to naturalize in open meadows, Evening Primrose provides dependable color while supporting a wide range of beneficial wildlife.
Garden Uses
Evening Primrose is well suited for native plant gardens, wildflower meadows, prairie restorations, cottage gardens, pollinator gardens, rock gardens, sunny borders, slopes, roadside plantings, and naturalized landscapes. Many spreading species also make attractive flowering groundcovers in difficult sunny locations.
These graceful flowers combine beautifully with coneflowers, black-eyed Susans, gaillardia, liatris, coreopsis, salvia, lavender, yarrow, ornamental grasses, penstemon, asters, and other drought-tolerant native perennials. Their open blooms also add a light, natural appearance to fresh-cut wildflower bouquets.
Growing Information
Most Oenothera species grow best in full sun but tolerate light afternoon shade. They perform well in average, sandy, gravelly, rocky, or moderately fertile soils with good drainage. Depending on the species, mature plants typically range from 12 to 48 inches tall with spreads of 12 to 36 inches or more.
Sow seeds outdoors in spring or autumn, or start indoors 6 to 8 weeks before the final frost. Cover seeds lightly with soil and maintain even moisture until germination, which generally occurs within 10 to 21 days. Many perennial species establish quickly and begin flowering during their first or second growing season.
Once established, Evening Primrose requires very little maintenance. Water only during prolonged drought and remove spent flower stalks if desired to encourage continued blooming. Many species spread naturally through underground rhizomes or self-sowing, making them excellent choices for naturalized landscapes.
