Himalayan Balsam

This plant is an invader having escaped from gardens to monopolise some areas particularly along streams and rivers. It is increasing its territory in Hetton Bogs and is appearing some distance from Hetton Burn which flows through the whole site. It is an attractive plant but once established cannot be removed. While out walking today I noticed it shooting up in vast numbers giving the impession that it will be more rampant than previous years.
