Reynoutria multiflora, commonly known as tuber fleeceflower, is an herbaceous perennial vine native to a variety of habitats in central and southern China and Taiwan, including forest margins, grassy slopes, and along streams. It can grow up to 13 feet tall from a woody tuber and produces small, white or greenish-white flowers in dense, showy panicles during the summer months. The plant is also known for its extensive root system, which contributes to its potential invasiveness.

Tuber fleeceflower is valued for its vigorous growth and is often used in traditional Chinese medicine. It is also planted for soil stabilization and erosion control due to its robust root system. In cultivation, it prefers full sun to part shade, requires moderate water, and thrives in well-drained soils. However, gardeners should be cautious as it can become invasive outside its native range, spreading through both rhizomes and seeds. It is important to manage its growth and prevent it from escaping into natural areas.CC BY-SA 4.0
