Oenothera speciosa is a species of evening primrose known by several common names, including pinkladies, pink evening primrose, showy evening primrose, Mexican primrose, and amapola.

It is a herbaceous perennial wildflower native to 28 of the lower 48 U.S. states (Alabama, Arkansas, Arizona, California, the Carolinas, Connecticut, Florida, Georgia, Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Missouri, Mississippi, Nebraska, New Mexico, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas, Utah, Virginia, and West Virginia) as well as Chihuahua and Coahuila in Mexico. It frequently escapes from gardens. The specific name, speciosa, means "showy".

The plant's wild habitat includes rocky prairies, open woodlands, slopes, roadsides, meadows and disturbed areas. While it makes an attractive garden plant, care should be taken with it as it can become invasive, spreading by runners and seeds. This drought-resistant plant prefers loose, fast-draining soil and full sun.
