About Rose evening primrose
Oenothera rosea, commonly known as 'Rosy Evening-primrose', is a perennial herbaceous plant from the Onagraceae family, valued for its delicate, deep pink flowers that open at dusk and last until morning. It forms compact mounds of dark green foliage, making it ideal for borders, rockeries, or as ground cover in low-maintenance gardens. Its prolonged blooming from spring to autumn adds a vibrant splash of color.
Native range
Mexico, Central America, and northern South America
Care tips
It requires full sun exposure for abundant flowering, although it tolerates some partial shade. This plant is drought-tolerant once established, so watering should be moderate, allowing the substrate to dry out between waterings to prevent waterlogging. It prefers well-drained soils, even poor or sandy ones, and a common mistake to avoid is overwatering or heavy soil, which can lead to root rot. It can become invasive if conditions are very favorable, so controlling its spread is recommended.
