This is an introduction from southern Europe which is grown in gardens and at this site it was used a hedging material which had got out of control. However some had escaped properly to the top of a wall opposite the hedge and was way out of reach as the wall was over 2 metres tall.

Bupleurum fruticosum has escaped in very few places in southern England only.
