Interesting Facts About Japanese Knotweed

 Japanese knotweed Facts

  • Japanese knotweed actually won awards when it was introduced into the UK at Kew gardens during the mid 1850' as an ornamental plant. However our victorian gardeners soon changed their tune when they realised what they had done!

  • Japanese Knotweed  is part of the Dock family (Polygonaceae)

  • British Rail originally used Japanese knotweed to stabilise railway embankments

  • The young spring shoots can be cooked and eaten, apparently they taste a bit like rhubarb, due to the amount of Oxalic Acid, we'll take their word for it!

  • The root is used in Chinese & Japanese herbal medicinal remedies as a laxative! This is because the root contains emodin

  •  The root also contains Resveratrol which is used as a natural herbal 'wellbeing' supplement!

  • The Rhizomes can grow up to 3 metres deep and 7 metres away from the plant, remember each cane or stem is a separate plant with its own root or rhizome system

  • Following its arrival in the UK and the interference of the birds and the bees (quite literally!) there is now a hybrid 'version' (Fallopia x bohemica) which is a cross between the UK's Giant knotweed and Japanese knotweed.

  • Other common names for Japanese knotweed are monkey weed, elephant ears, Hancock's curse,  donkey rhubarb, sally rhubarb, (it definitely isn't related to rhubarb though),  Japanese bamboo, American bamboo, and Mexican bamboo

  • The natural habitat for Japanese knotweed is the mountainous volcanic slopes in Japan/Far east

  • We only have the female or male species in the UK (opinion is divided as to which sex is actually here) hence the reason why the plant does not spread by seeds.

  • A cluster of Japanese knotweed is called 'a stand'
