Product Details
Evening primrose plants for sale here are Oenothera biennis, a tall native wildflower with lemon-yellow blooms that open at dusk. We ship them bare-root in packs of 25, 50, 100 and 500, for moon gardens, meadows, pollinator plantings and wholesale buyers.
Evening Primrose Size, Zones and Sun
Evening primrose reaches 3 to 5 feet tall on a stout, leafy stem, with a spread of 2 to 3 feet. It's hardy in zones 4 to 9. Full sun is best, and part shade is fine. Well-drained, sandy or gravelly ground is ideal, and it doesn't need rich soil.
Evening Primrose Flowers
The four-petaled flowers are pale lemon yellow, with a mild lemon scent, and they open in the evening, then fade the next day. Plants flower from June into September. By late summer the stems are heavy with seed pods.
Evening Primrose and Pollinators
Night-flying moths come for the scent, and bees visit in the early morning. Moth larvae feed on the buds, and birds eat the seed in fall. Our guide on growing and caring for evening primrose gives more detail.
Where to Plant Evening Primrose
Place it where you sit in the evening: beside a patio, along a path or at the back of a border. It also suits meadows, roadsides and dry, sunny slopes. For a full night garden, see our guide to building a moon garden with native plants.
Planting Evening Primrose Bare-root
Let the roots sit in water for an hour. Dig a hole that fits them without bending, put the crown level with the ground and fill in around it. Water thoroughly, leave 18 to 24 inches between plants, and keep watering until you see new leaves.
Buying Evening Primrose in Bulk
At 2 feet apart each plant takes about 4 square feet, so a pack of 25 covers roughly 100 square feet, 100 plants cover around 400 and 500 plants cover about 2,000. Packs of 25, 50, 100 and 500 suit a border or a whole meadow.
Good to Know About Evening Primrose
This is a biennial: it forms a leafy rosette the first year and flowers the second. It then drops seed and renews itself by self-seeding, so a planting keeps going. If you'd like fewer volunteers, cut the seed heads before they split.
Evening Primrose for Meadows and Moon Gardens
Few flowers do more for an evening garden. With white and silver foliage plants beside it, the yellow blooms glow as the light fades.
