Hi, I have been struggling to identify a horrible plant, similar in nature to J knotweed in that it spreads vegetatively, by root or fragments, and has roots on each node, it grows in sections like knotweed. It's leaves are 10cm in length and hairy. In damp areas of soil it can grow up to 3ft in height. It thrives in semi shady moist areas amongst other plants.
The flowers are at the tip of the plant in clusters and are mostly white with pink tinge.
The plant stem is thin in diameter about 1cm, with node/sections at about 10-12cm. The stem is green with pink tinge at node areas.
Could this be Himalayan Knotweed?
Please help us help us identify this spreading plans and please could you give tips on how to irradiate it.
Many thanks!!
