Pink Evening Primrose is an upright to sprawling, 1 1/2 ft. perennial, which spreads to form extensive colonies. Its large, four-petaled flowers, solitary from leaf axils, range in color from dark pink to white. The delicate-textured, cup-shaped blossoms are lined with pink or red veins. A hardy and drought resistant species that can form colonies of considerable size.

Evening primroses are useful in a wide variety of semi-wild garden settings: in rock gardens, wildflower meadows, and naturalistic borders and along the edges of roads and trails.Plants are likely to die of root rot if the soil is not well drained. They do fine in high humidity.
