This plant is one I look forward to seeing in early Spring. Its fresh green leaves spring up very quickly and soon result in masses of white flowers. In fact it so often grows at the bottom of countryside hedges that one of its other common names is Jack-by-the-Hedge. When it is about to flower the orange tip butterfly is usually seen flitting about. It lay its eggs on the fresh leaves of A. petiolata on which the caterpillars of this single brooded butterfly feed.

It is very common in England and Wales although less so in Scotland but even though it is very common I wouldn't classify it as a weed.
