Similarities to Japanese Knotweed

Another frequent case of mistaken identity occurs with this climbing plant. Bindweed’s leaves share Japanese knotweed’s heart-shaped leaves which can lead to raising concerns amongst homeowners.

Differences between Hedge Bindweed and Japanese Knotweed

The leaf shape in Bindweed is heart-shaped and is comparable to knotweed. However, Bindweed does not have a flat edge as knotweed does.

The biggest difference between bindweed and Japanese knotweed is strength. Bindweed cannot stand up by itself and needs to bind itself around other plants (hence the name). Japanese knotweed will never entwine another plant; it simply grows over the top of them.

Another key distinguisher is its large pink or white trumpet flowers which start growing in early summer, these are unmistakably different to knotweed’s small, creamy white flowers.
