japanese knotweed
Fallopia japonica
identification...
Japanese Knotweed forms dense clumps of up to 3 metres in height. It has large, oval green leaves and a stem that is hollow and similar to that of bamboo.
In early Spring (although it can be later in the year) the plant produces fleshy red-tinged shoots. These can reach a height of 1.5 metres by May and 3 metres by June, growing as much as 5cm per day.
Towards the end of August, clusters of cream flowers develop and then produce seeds that are non-viable. The plant dies back between September and November.
The use of equipment that is likely to result in further spread of Japanese Knotweed must ALWAYS be avoided!
DO NOT - cut, scythe, flail, mow or disturb the ground.
