'''Pink primrose''' (''Oenothera speciosa''), also known as '''Pinkladies''' and '''Showy evening primrose''', is a herbaceous [[perennial plant|perennial]] [[wildflower]] native to the southeastern [[United States]] and [[Mexico]]. The species name ''speciosa'' means "showy".
The Pink primrose has glaborous (smooth) to pubescent stems that grow to 50 cm in height. The pubescent [[Leaf|leaves]] are alternate with very short or no [[Petiole (botany)|petiole]] (sessile), reaching 10 cm long to 4 cm broad. They are variable in shape, from linear to obovate, and are toothed or wavy-edged.
It produces single, four-petaled, cup-shaped flowers on the upper leaf axils. These fragrant shell-pink flowers bloom throughout the summer into early autumn. The 1.5-2" flowers start out white and grow pink as they age. The flower throats, as well as the [[carpel|stigma]]s and [[stamen]]s, have a soft yellow color. It blooms both day and night, but typically in the pre-dawn hours, closing when the full sun hits them. They bloom from March to July, and occasionally in the fall.
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 flower is frequented by several species of [[insect]], but [[moth]]s are the most common as the flowers are mostly open at night.
This drought-resistant plant prefers loose, fast-draining [[soil]] and full sun.
This plant is also frequently referred to as a buttercup, though it is not a true buttercup. Other names include Mexican primrose and Amapola.
