Oenothera kunthiana, commonly known as Kunth’s Evening Primrose, is a perennial herb native to grasslands and open, rocky places in Mexico and Central America. It typically grows to a height of 2 feet (0.6 meters) and a width of 0.5-1 feet (0.2-0.3 meters). This plant forms a rosette of lance-shaped leaves, with flowering stems that bear large, showy pink and white flowers that open in the evening and close by the next noon, blooming profusely in the summer and fall.

Kunth’s Evening Primrose is valued for its extended flowering period and the striking contrast between its pink petals and yellow stamens. It is often used in borders, rock gardens, and as a ground cover due to its low maintenance and drought tolerance. It thrives in full sun and requires well-drained soil, tolerating a range of soil types from sandy to loamy. While it is drought-tolerant, moderate watering can encourage more abundant blooms. It is not known for serious pest or disease problems, but overwatering can lead to root rot.CC BY-SA 4.0
