Varieties: none.[1]
Description
"Usually pubescent, branched biennials or perennials. Leaves alternate, the upper reduced, sessile or subsessile, the lower frequently petiolate. Inflorescent terminal, flowers solitary from axils of bracts or reduced upper leaves. Calyx tube (hypanthium above ovary or capsule) prolonged; lobes (sepals) 4, acute.

"Pubescent biennial, usually with decumbent, basal branches, stems to 7.5 dm long.

Calyx tube 2-2.5 cm long, lobes 6-12 mm long; petals yellow to reddish, 8-25 mm long; anthers 3-6 mm long. Capsules pubescent, cylindric, usually slightly arcuate, 2.5-4 cm long, 3-4 mm broad; pedicels absent or to 5 mm long; seeds brownish, angulate, 1.2-1.4 mm long, ca. 0.8 mm broad, pitted."[2]
Distribution
O. laciniata ranges from Maine to North Dakota, then south to southern Florida and Texas. There are also populations in California.[1]
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, O. laciniata occurs in shrub bogs, pine flatwoods, and pine savannas. It is observed to be a ruderal species and has been found in disturbed areas such as sandy vacant lots, moist roadsides, fallow fields, and railroad beds. Soil types include sandy loam, loam, and loamy sand. Associated species include Drosera, Calopogon, Briza, and Cerastium.[3] It is a common weed found in soybean, corn, and cotton crops in the southeastern U.S.[4] It has become an invasive species in central and south America, Europe, Africa, and Australia.[5]
Phenology
O. laciniata flowers from January through July with peak inflorescence in April and fruiting from January through June.[3][6] Flowers typically bloom at night.[7]
Seed dispersal
The fruits are dehiscent.[5]
Seed bank and germination
Seeds can remain viable in the soil for decades.[8]
Fire ecology
It has been observed growing in annually burned pine savannas.[3]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Oenothera laciniata at Archbold Biological Station:[9]
Vespidae: Polistes dorsalis hunteri
Use by animals
Seeds are eaten by bobwhite quail, morning doves, and American goldfinches. Cottontail rabbits and white-tailed deer browse on the foliage.[7]
Diseases and parasites
It is a host for clouded and tarnished plant bugs that are common pests of cotton.[10]
Conservation and management
It is a noxious weed in soybean, cotton, and corn crops in the southeastern U.S.[4] In a reduced-tillage system, it may be difficult to control when timely applications are not made.[11] This species' small size and slow growth make February and early March herbicide applications most effective.[12]
Cultivation and restoration
Historically, it was used by Cherokee Indians as a potherb and to make body wash.[13]
