Plants Commonly Mistaken for Japanese Knotweed

Bindweed

Bearing heart-shaped leaves like its Japanese twin, bindweed also has a rapid growth spurt when it first appears in the springtime. However, unlike Japanese knotweed, bindweed isn’t capable of supporting itself and, instead, makes its vertical ascent by coiling itself around the stems of other standing plants.

Bindweed also boasts large flowers in the summertime, clearly differentiating itself from traditional Japanese knotweed.

Russian Vine

Much like Japanese knotweed, Russian vine has similar looking leaves and flowers, while it is also fast growing. On the other hand, it is also similar to bindweed in that it relies on other plants to grow upward, twisting and climbing around the stems of taller, more solid vegetation.

Bamboo

Perhaps the most widely known of its contemporaries, bamboo grows tall like knotweed and also has visible nodes on its stem, making the two very similar in appearance. That being said, bamboo stems are considerably denser than its Asian brethren and boasts a strong sturdiness lacking in Japanese knotweed. Bamboo leaves are also notably narrower and longer.

Broadleaf Dock

Part of the same family, broadleaf dock shares numerous characteristics with Japanese knotweed, from its arrangement of leaves to the spiky shape of its flowers and stems. However, this plant is typically shorter than Japanese knotweed and contains a foamy substance in its stem, clearly visible when cracked open.
