Taxonomic notes
Synonyms: Gaura angustifolia Michaux[1]
Varieties: Gaura angustifolia var. angustifolia[1]
Description
Observed to be an abundant weedy species in roadside sods.[2]
"Usually coarse, branched annuals or perennials. Leaves mostly alternate. Inflorescence terminal, spike-like with or without axillary branches from upper leaves or bracts. Petals white to pink; stigmas 3-4 lobed. Fruit woody, indehiscent."[3]
"Plant to 2m tall, stem strigose. Leaves narrowly elliptic or lanceolate, strigillose to glabrous, to 8 cm long and 1 cm wide, reduced upward, frequently fascicled, acute, remotely denticulate or serrulate, the basal sinuate; sessile. Spikes usually branched, main branch to 3 dm long, strigose; bracteoles caduceus. Sepals 3.5-6 mm long; petals 2.5-3 mm long; anthers 1.2-1.5 mm long; styles exserted ca. 5.5 mm. fruits acutely 3-4 angled, sides concave, canescent, ovoid, 6-8 mm long, 2-3 mm broad; pedicels 1-2 mm long."[3]
Distribution
O. simulans is endemic to the Coastal Plain, ranging from eastern North Carolina to southern Florida, then west to eastern Texas.[1]
Ecology
Habitat
This species can be found in marshy depressions surrounded by live oak hammocks, pine-oak woodlands, grass and succulent cover, beach hammocks, longleaf pine forests, old fields, along oak scrub edges, and bordering salt marshes.[2] O. simulans has been observed to grow in moist loamy, loose, and silty sands in open areas.[2] This species is "one of the most aggressive pioneers in disturbed areas" such as plowed fire lanes, along roadsides, vacant lots, clear cut pinewoods, and along fence rows.[2] Associated species includes Pinus, Quercus, Papaya, Forestiera, Bumelia, Eugenia, Piscidia, Agave, Yucca, Juniperus, Sabal, Bumelia lanuginosa, Crateagus floridana, Pinus elliottii, Myrica cerifera, Pinus palustris, and Conzya.[2]
Phenology
This species flowers from May through September.[1]
Fire ecology
This species has been found in areas of open burned pine-oak woodlands.[2] Populations of Oenothera simulans have been known to persist through repeated annual burning.[4]
Conservation, cultivation, and restoration
Cultural use
Evening-Primroses can be used as a potherb for their asparagus-like quality of greens, and Native Americans would use the pith to make soup. In England, there was a problem of using the leaves as a tea filler.[5]
