Fallopia convolvulus, commonly known as Black-bindweed or Wild Buckwheat, is a fast-growing annual vine native to a variety of habitats including fields, roadsides, and open woodlands across Europe, Asia, and northern Africa. It can grow up to 59 inches long, with stems that twine clockwise around other plants for support. The leaves are typically triangular to heart-shaped, and the plant produces small, inconspicuous greenish-pink to greenish-white flowers clustered on short racemes during the summer months.

Black-bindweed is not typically cultivated for ornamental purposes due to its invasive nature, but it can be found in wildflower mixes for use in restoration projects or naturalized areas. It thrives in a range of soil types, from clay to sandy loams, and prefers full sun to part shade. While it requires minimal maintenance, it can become problematic if not managed properly, as it competes with crops and other plants for resources. In regions where it is not native, it can be invasive, so it is important to check local regulations before planting. It is invasive in North America, where twining vines foul crops and even clog harvesting machinery.CC BY-SA 4.0
