An invasive, non-native plant.

This bulbous plant produces distinctive flowering stems with three angles, hence the name.

What's the problem?

The pendent white flowers are followed by large seeds which are attractive to ants and are therefore spread around them. The plant readily escapes into the wild is found along roadsides banks and verges, hedgerows, woodland edges, field edges and on waste ground. It forms very dense colonies that can outcompete other spring flowers like primroses and violets. On some roadside verges and banks it forms dense stands for many meters. It is most common in southern and western Britain, but is on the increase and spreading further north.
