About this plant
The Russian vine or 'mile-a-minute' is the best known and loved of the form Fallopia baldschuanicum. It can climb with ease and rapidity and accomplishes around 12 metres in height. In late summer it covers itself in masses of white frothy flowers that make a light and appealing cloud across the foliage mass. The beautiful weed Fallopia japonica (the Japanese knot weed), forbidden to gardeners, belongs to this family. Variegated forms of this plant that are of a more domestic habit are now available with attractive foliage in shades of green and white.
