The lace vine plant or silver lace vine (Fallopia baldschuanica) is an easy-to-grow plant that is a member of the Polygonaceae family. It is a native plant to China, particularly western China, Tibet and Tajikistan. It is recommended for U.S. Department of Agriculture hardiness zones 4 through 7.
Silver lace vine is a fast-growing herbaceous vine that can grow from 12 to 15 feet in one growing season. It typically grows to a length of about 25 to 35 feet during its lifespan and has 3 ½-inch, oval-shaped leaves that turn bright green once they are mature. It produces small, fragrant, showy white to pale pink blooms from early to late summer. It is considered a weed in some areas because of its vigorous growth.
The silver lace vine prefers full sun to part shade. It does well in any type of soil, but prefers a soil with sand or clay. If grown in a lean or poor type of soil, it is typically not as robust and the growth and spreading is less invasive. The silver lace vine prefers a dry to moist type of soil. It is somewhat tolerant of drought.
Because of its spreading nature, the silver lace vine is sometimes used to cover arbors and pergolas as a way to provide shade. It typically needs a trellis to climb, but will happily spread over fences and up walls. When the silver lace vine is not given something to climb, it will spread out across the ground. An excellent ground cover, it can hide the flaws of the land such as, rotting stumps, uneven areas or unmovable rocks. The silver lace vine may also be used to help prevent banks from washing away by stabilizing the soil.
Pruning of the silver lace vine may be done in late winter through early spring. The plant may be cut back to as much as 1 to 3 feet from the ground during this time. Maintenance and additional pruning may also be done throughout the year to keep the silver lace vine smaller and shorter, when needed.
It is simple to transplant the silver lace vine. Because it spreads with underground rhizomes, each little root can form a new plant. These rhizomes can be dug from the ground and easily transplanted elsewhere. The silver lace vine does not do well with other vines, however, and its vigorous growth may smother other plants if it is placed too close to another.
