What is Japanese Knotweed and where does it grow?

Japanese knotweed (Fallopia japonica) is an invasive plant that was introduced to North America in the late 1800s. It is a fast-growing perennial that can reach up to 10 feet in height. Japanese knotweed has hollow stems with nodes (joints) and small, heart-shaped leaves. The flowers are small and white, and they grow in clusters.

Japanese knotweed can be found in open areas such as fields, forest edges, and roadsides. It is especially common in disturbed areas such as construction sites. Japanese knotweed spreads rapidly through rhizomes (underground stems) and seeds.

The plant can produce up to 20,000 seeds per year, and the rhizomes can extend up to 20 feet from the parent plant. Japanese knotweed is a problem because it invades natural areas and competes with native plants for resources.
