Plant Source Info:

Polygonum Cuspidatum L.; Fallopia japonica, synonym Reynoutria japonica, commonly known as Asian knotweedor Japanese knotweed,s a large,herbaceous perennial plant of the knotweed and buckwheat family Polygonaceae. It is native to East Asia in Japan, China andKorea. In North America and Europe the species is very successful and has been classified as an invasive species in several countries.In the UK and Australia, it is illegal to have any of this species growing on one's property.

 

Japanese knotweed has hollow stems with distinct raised nodes that give it the appearance of bamboo, though it is not closely related. While stems may reach a maximum height of 3–4 m (9.8–13.1 ft) each growing season, it is typical to see much smaller plants in places where they sprout through cracks in the pavement or are repeatedly cut down. The leaves are broad oval with a truncated base, 7–14 cm (2.8–5.5 in) long and 5–12 cm (2.0–4.7 in) broad,[6] with an entire margin. Theflowers are small, cream or white, produced in erect racemes 6–15 cm (2.4–5.9 in) long in late summer and early autumn. English names for Japanese knotweed include fleeceflower, Himalayan fleece vine, monkeyweed, monkey fungus, Hancock's curse, elephant ears, pea shooters, donkey rhubarb (although it is not a rhubarb), sally rhubarb, Japanese bamboo, American bamboo, and Mexican bamboo (though it is not a bamboo). In Chinese medicine, it is known as Huzhang (pinyin:Hǔzhàng), which translates to "tiger stick".
