About Oenothera gaura W.L.Wagner & Hoch
Oenothera gaura W.L.Wagner & Hoch, commonly called biennial beeblossom, is a tall, weedy plant species. Individuals have white to light pink flowers when blooming, and mature leaves turn red. The plant has a flexible structure that sways in the wind, which aids in seed dispersal. Several hairy stems emerge from the top of the plant where flowers grow, and this feature is the easiest way to identify the species. Flowers typically have 4 petals, 8 stamens, and 1 pistil, and are mostly pollinated by bees and other insects. This is a biennial species: it starts as a small plant in its first growing season, and reaches 0.9–1.8 m (3–6 feet) tall during its second growing season, completing its full life cycle over two growing seasons, reaching full maturity by the end of the second season. The fruits are ribbed or ridged capsules, and are occasionally woody. It produces small seeds that are easily dispersed by wind and other methods. This species naturally occurs throughout eastern and central North America, ranging as far north as Quebec, Canada. In the United States, it can be found in Connecticut, Delaware, Georgia, Illinois, Kentucky, Massachusetts, North Carolina, South Carolina, New York, Texas, and Virginia. It grows primarily in prairies across North America, as well as in dry, rocky areas and deserts. It prefers sunny, dry locations, and can adapt to a wide range of habitats thanks to its ability to grow deep roots. To survive wet winters, it requires a dry spot with light soil.
