Supporting Evidence
Photo of my evidence.
The leaf of the Japanese Knotweed is usually in the shape of a spade. And the leaf of a Giant Knotweed plant is in the shape of a heart. As you can see, this leaf is obviously the shape of a spade. The veins across the leaves resemble the veins on a Giant Knotweed plant but are more like a Japanese Knotweed Plant.

We know that this plant is Japanese knotweed because Japanese Knotweed has the ability to grow through the pavement.

The stem of these plants are hollow. Also, the stem of the Japanese Knotweed plants are hollow as well. To prove that this plant is not Giant Knotweed, we know that Giant knotweed is not hollow like Japanese Knotweed
