Buddleia (butterfly bush) removal in Neath, Port Talbot & the Neath Valley
The purple butterfly bush that seeds itself into every wall, bridge joint and chimney in Swansea. It is a genuine problem for buildings: roots widen mortar joints and brick cracks, and a mature buddleia can lift coping stones off a bridge parapet.

Local picture
Heavy industrial ground along the Neath and lower Tawe carries knotweed almost continuously, and the River Neath and its tributaries move balsam seed down the whole valley. Covered by Neath Port Talbot County Borough Council on council land.
Pressure from invasive plants here: Severe. Buddleia (butterfly bush) is less common here than elsewhere, so we check identification carefully.
Legal status: Not on Schedule 9, but a listed problem plant for buildings.
