Mexican Evening Primrose is a gorgeous accent plant in the spring and summer months. However it is rather unattractive in the winter, since the stems die back after blooming. Not to worry, this plant recovers quickly in the spring. Mexican Evening Primrose is commonly grown in the Southwest as a spring colored plant for several reasons. This plant rapidly grows and can be 6 inches high with slender stems and narrow (1 to 1 1/2 inches) leaves. The plant also profusely produces dainty pale purple to rose pink cup-shaped flowers. The flowers bloom in the daylight and do not have any strong fragrance. Also, the Mexican Evening Primrose is only susceptible to the flea beetle. If the foliage begins to thin out consult your local nursery. Mexican Evening Primrose can be used as a border plant, bedding plant, an under-plant, along fences, walkways, in containers, or in rock gardens. It can be used as a ground cover but not recommended since it is not attractive all year long in most climates. This plant looks its best in transitional, natural, desert or wild landscapes. Mexican Evening Primrose looks out of place in formal gardens. Mexican Evening Primrose can be planted from containers all year round and from divisions in the spring. Care should be given when planting so that plants are not planted to close together. They should be planted 2 feet apart for a cover in 2 years or less. If planted closer, the plant will spread quickly and become invasive. Mexican Primrose should be clipped almost to the ground after blooming.
