Oenothera triloba
Oenothera triloba, with common names stemless evening primrose and sessile evening primrose[1] is a flowering plant in the primrose family. It is native to North America, where it is primarily found in northern Mexico and in the south-central United States.[2] It is found in dry, open areas such as glades, prairies, and sometimes even lawns. It appears to respond positively to soil disturbance.[3][4] It is a winter annual that produces large yellow flowers in the spring. The flowers open near sunset.[3] UsesAmong the Zuni people, the plant is used as an ingredient of "schumaakwe cakes" and used externally for rheumatism and swelling.[5] They also grind the roots and use them as food.[6] References
