This is an annual or short-lived perennial herb producing a spreading stem from a hairy rosette of deeply cut or lobed leaves. Flowers occur in the axils of leaves higher on the stem. Each flower has pale to deep yellow petals up to about 2 centimeters long which fade orange, pink, or red with age. The fruit is a cylindrical capsule up to 5 centimeters in length. O. laciniata leaves range from oblanceolate to elliptic in shape, and may be irregularly lobed or pinnatifid. [2]

Habitat and distribution

O. laciniata's range stretches from Maine to North Dakota, and extends south to Florida and Texas. Additionally, populations have been reported in California. [3]

Within the southeastern United States' coastal plain, this species can be found in habitat types such as pine flatwoods, pine savannas, and shrub bogs. [4]
