It's midmorning and overcast. Although there's an occasional slight breeze, the air is heavy. The bugs are out and biting! Thunderstorms are forecasted for today. All this rain has made my backyard grass grow another 3 inches and these tall, dense stalks overtake my backyard. I have to mow my lawn every week. And these thick stalks, I cut them back, but they come back with a vengeance! These resilient stalks are what I'm identifying today.
Japanese Knotweed grows in a dense bush. It also has noticeable joints along its stem, like bamboo. This picture shows the compact stems. Along each stem, you can see the visible joints. Characteristic of Knotweed is its distinctive purple specks. If you look closely, you can see these specks in the picture.
The leaves of the Japanese Knotweed are elongated, simple, oval, and spade shaped with an abrupt narrow tip and a smooth edge. The leaves also alternate on zig zags stems. Here, in the middle of the picture, you can see the leaves growing from the points of the zig zags. Measuring a few leaves, the largest one was about 15 cm long (measured along the center of the leaf from the bottom to its tip), and 9.5 cm at its widest. This could not be the similar species, the Giant Knotweed, which has elongated heart shaped leaves that are typically 15 cm to 40 cm long.
