Oenothera versicolor, commonly known as Evening Primrose, is a deciduous perennial herb native to Western South America, including regions such as grasslands, open woodlands, and prairies. It typically grows to a height and width of approximately 1 foot. Oenothera versicolor is known for its striking bi-colored flowers that transition from yellow to orange and red, blooming profusely from late spring to early fall. The flowers are particularly showy and open in the evening, hence the common name.

Evening Primrose is valued for its vibrant flowers and ability to attract pollinators such as bees and moths. It is often used in borders, rock gardens, and as a ground cover due to its low-growing habit. This plant is drought-tolerant, making it suitable for xeriscaping and gardens with low water availability. It thrives in full sun and requires well-drained soil. While generally low-maintenance, it can self-seed prolifically, which may be considered invasive in some areas. Evening Primrose oil, extracted from the seeds, is used for its purported medicinal properties.CC BY-SA 4.0
