Habitat Woodland

An invasive, non-native plant.This innocent looking relative of the dead-nettles produces spreading stems (stolons) with beautifully variegated leaves and spikes of yellow flowers. It’s very common as a garden plant and widely sold.

What's the problem?

Once this species gets into the wild, it rapidly spreads and carpets the floor to the exclusion of other plants. The smallest stolon fragment with just one pair of leaves can grow into a new colony, and stolons break readily if the plant is pulled up. It’s usually found in shady habitats such as woodland edges, hedgerows, roadside banks and stream sides. It is increasing rapidly in the wild and beginning to impact sites at which species of conservation interest grow; in a recent survey it was found at the majority of Spreading Bellflower Campanula patula sites visited.
