Buckwheat Vine 10 Seeds Brunnichia ovata

Brunnichia ovata, commonly known as the Buckwheat Vine, is a vigorous, deciduous climbing vine native to the southeastern United States, where it thrives in moist habitats such as floodplains, riverbanks, swamps, and low woodlands. Belonging to the buckwheat family (Polygonaceae), this twining perennial can reach lengths of 30 feet or more, using surrounding vegetation or structures for support as it climbs. Its slender, reddish-brown stems bear broad, oval to heart-shaped leaves that provide dense foliage throughout the growing season. During summer, Brunnichia ovata produces small, greenish-white flowers arranged in loose clusters, which are modest in appearance but give way to distinctive winged, reddish-brown fruits in late summer to fall. The fruits are both ornamental and an important food source for wildlife, including birds and small mammals. The plant prefers full sun to partial shade and thrives in wet, loamy, or clay soils, tolerating seasonal flooding. Though often found in natural wetland areas, it can also be cultivated as a native ornamental vine for covering fences, trellises, or arbors. With its attractive fall coloration and ecological value, Brunnichia ovata serves as both a decorative and functional species, contributing to soil stabilization and providing habitat in riparian and wetland ecosystems.
