The perennial plant is native to southern Louisiana and Texas.[4][5] The specific epithet is after Ferdinand Jacob Lindheimer, a German-born botanist who collected extensively in Texas for Harvard University professor Asa Gray. It is commonly grown as an ornamental plant.

Description

Oenothera lindheimeri is a perennial herbaceous plant growing to 50 to 150 centimeters (20–60 in) tall, with densely clustered branched stems growing from an underground rhizome. The leaves are finely hairy, lanceolate, 1 to 9 cm (1⁄2–3+1⁄2 in) long and 1 to 13 mm (1⁄16–1⁄2 in) broad, with a coarsely toothed margin.

The flowers are produced on a 10-to-80-centimeter-long (5–30 in) inflorescence; they are pink or white, 2 to 3 cm (3⁄4–1+1⁄4 in) in diameter, with four petals 10 to 15 mm (3⁄8–5⁄8 in) long and long hairlike stamens, and are produced from the beginning of spring until the first frost.[6][7]

Cultivation

Oenothera lindheimeri is commonly grown as an ornamental plant. It is used in either garden beds or pots for accent colour and a delicate texture. It grows best in full sun and can survive lengthy periods of drought.

Several cultivars have been selected for varying flower color, from nearly pure white in 'Whirling Butterflies' to darker pink in 'Cherry Brandy' and 'Siskiyou Pink'. In some, the petals are white at dawn then turning pink before falling off at dusk.

Although a perennial rated USDA Zone 5(6)-9 for hardiness it may not overwinter reliably, and is often treated as an annual outside its native areas. In colder climates a heavy winter mulch is necessary.[8]

This plant has gained the Royal Horticultural Society's Award of Garden Merit.[9][10]

Etymology

Oenothera: Etymology is uncertain, but it is believed to be derived from the Greek words οίνος θήρα (oinos thera) meaning "wine seeker".[11]

Gaura: Derived from Greek γαῦρος (gaûros) meaning "superb". Named in reference to the stature and floral display of some species in this genus.[12]

Lindheimeri: Named for Ferdinand Lindheimer (1801–79), who discovered the plant Lindheimera texana.[13]
