Fallopia baldschuanica (syn. Polygonum baldschuanicum) is an Asian species of flowering plant in the knotweed family known by several common names, including Russian-vine, Bukhara fleeceflower, Chinese fleecevine, mile-a-minute and silver lace vine. It is native to the southern Asia west of the Himalayas and is growing wild in parts of Europe, Africa, and the United States as an introduced species.
Fallopia baldschuanica is grown as an ornamental plant for its flower-laced vines. The white flowers are decorative and provide nectar and pollen for the honey bee. As it is fast-growing, it is used as cover for unsightly fences and other garden structures. It can become invasive, however.
The specific name baldschuanica 'from Baldzhuan' refers to the area of the city of Baldzhuan, in Tadjikistan.
Description Fallopia baldschuanica is a vining plant with woody, climbing stems at least in length. The pointed oval or nearly triangular leaves are up to long and borne on petioles. The inflorescence is an open array of narrow, branching, drooping or spreading clusters of white flowers, each cluster reaching a maximum of long. Flowers hang on short pedicels. Each five-lobed flower is just under a centimeter long and white to greenish or pale pink, sometimes turning bright pink as the fruit develops. The fruit is a shiny black achene about wide.Flora of North America, Fallopia baldschuanica (Regel) Holub, 1971. Bukhara fleeceflower, mile-a-minute vine
Taxonomy Fallopia baldschuanica was first described as a species in the Polygonum genus named Polygonum baldschuanicum in 1884 by Eduard August von Regel. Many other classifications have been published, but the placement in Fallopia by botanist Josef Ludwig Holub in 1971 is the accepted classification. Alongside the rest of the genus it is part of the Polygonaceae family and has no subspecies. Although Plants of the World Online (POWO) lists it as a separate species from Fallopia aubertii native to China, there are botanists to prefer to combine the species under F. baldschuanica.Flora of China, Fallopia aubertii (L.

According to POWO the species has five homotypic synonyms.
