Oenothera fruticosa
Also called Shrubby sundrops, Narrow Leaf Evening Primrose, Southern Sundrops, Sundrops, Narrow Leaved Evening Primrose, Narrow Leaved Sundrops, Narrow Leaved Evening Primose
Oenothera fruticosa is a native North American perennial wildflower in the evening primrose family, grown for its yellow cup-shaped flowers and valued in pollinator and native gardens. It thrives in sun, sandy well-drained soil, and is tolerant of drought and poor soil.
Oenothera fruticosa, the narrowleaf evening primrose or narrow-leaved sundrops, is a species of flowering plant in the evening primrose family.
It is native to much of eastern North America, where it is found in a variety of open habitats, including dry woodlands, rock outcrops and moist savannas.
The seeds of Oenothera fruticosa are approximately 1-3 mm long and are arranged in two rows within each locule. They also contain a persistent endotegmen that is one cell layer thick. In shape, the seeds are club-like and taper near the stem. The capsule of Oenothera fruticosa is approximately 1 inch in width and are visible May through November. The plants can be propagated by taking tip cuttings and is best conducted with adult plants at the beginning of its growing season (early spring) or late in its growing season (fall). Seeds must be planted in spring or fall and need to be germinated at approximately 70 degrees Fahrenheit.
The Oenothera fruticosa has a wide range in the United States which consists of the eastern seaboard (New York- Florida) and as far west as Oklahoma. Within these regions, Oenothera fruticosa prefers lower elevations. In the state of North Carolina which is within its range, this species is found widely around the state except in the mountainous regions.Oenothera fruticosa grows best in sunny areas that have mostly acidic soil conditions and good drainage (sandy soils). The common sundrop is relatively resilient to drought, shade, extreme heat, and varying soil pH. Oenothera fruticosa is mostly found in grassy clearings, meadows, and along roadways in its native range.
The Cherokee parboil the leaves, rinse them and cook in hot grease as a potherb. In the modern day, the narrow-leaved sundrop is primarily a garden specimen. Historically Oenothera fruticosa was used by Native American tribes for a multitude of ailments. The tribes that used this species included the Iroquois, Cherokee, and Ojibwa. Although the tribes differ, the reasons that they used the narrow-leaf evening primrose, were similar. Its uses included helping with stomach issues, weightloss, bruising, and hemorrhoids. It is unknown at this time if Oenothera fruticosa is medically effective. Oenothera fruticosa has been included in research for breast cancer.
