Oenothera caespitosa, known commonly as tufted evening primrose, desert evening primrose, rock-rose evening primrose, or fragrant evening primrose, is a perennial plant of the genus Oenothera native to much of western and central North America. It produces a rosette of lobed or toothed leaves each up to 36 centimeters long around a woody caudex.
There are many subtaxa, referred to as subspecies or varieties.
Oenothera caespitosa grows to 10 centimeters (4 inches) tall. It is good for rock gardens. The 4-petaled white flowers open at dusk and wilt the next morning, turning pink.
