False Buckwheat Fallopia scandens

Every year the false buckwheat vines grow up over the front porch railings and part way up the posts. They stay as the vines are attractive all summer into fall. Frost kills them but they are easy to pull off and dispose of, no thorns, stickers or burs.

false buckwheat plant

False Buckwheat is one of those plants found worldwide. There are varieties of it so the population is partially the native one and partially an imported variety. The plant is not concerned and grows abundantly under the right conditions.

Numerous vines come from the rootstock. These cover the ground and any object or plant they encounter. The vines can be thick enough to blanket and smother these objects. They look light weight but are heavy enough en masse to bend small plants or saplings to the ground.

The flowers are small but make up for this with their number. The winged seed pods are pretty. Since the vines bloom for two to three months, they make pretty plants for growing on trellises.

False Buckwheat is an aggressive grower and seeds freely. The roots are persistent. In areas where the vines are mowed frequently, they will eventually die out.
