Question: What do Japanese knotweed stems look like in summer?

Answer: In summer, Japanese Knotweed stems are bamboo-like in shape and size, with purple speckles and green leaves sprouting from each node.

A Closer Look: 

In the summer, Japanese Knotweed (Fallopia japonica) stems are easily recognizable due to their bamboo-like appearance. These stems grow tall, typically reaching 2 to 3 meters in height, and are characterized by their hollow structure. A distinguishing feature is the presence of purple speckles that dot the green stems, adding a unique visual marker. At each node along the stem, vibrant green leaves sprout, further aiding in the identification of the plant during its active growing season.

The combination of bamboo-like stems, purple speckles, and green leaves at the nodes makes Japanese Knotweed particularly identifiable in summer, helping in early detection and effective management efforts to control its spread​.
