Knotweed grows in large, dense, clumps, upwards of 12 feet tall. In late summer plants will have small whitish flowers in lacy clusters.

Like a lot of invasive species that are causing problems now, people imported Japanese and Bohemian knotweed to America because it was pretty.

Knotweed leaves are oval to heart shaped and range in size from 3 to 12 inches long.

Knotweed has hollow, segmented stems which resemble bamboo.
