About

The perennial horseshoe vetch is an essential plant for the chalkhill and adonis blue butterflies as their caterpillars feed solely on it; it is also used by the Dingy Skipper. It is a low-growing plant, with yellow pea-like flowers that appear from May to July on chalk and limestone grasslands with short turf. The common name is thought to come from the shape of the seed pods, which are twisted and have horseshoe-like segments.

What to look for

Horseshoe vetch displays between five and twelve small, bright yellow, pea-like flowers on each head. It has small, green, folded, oval leaves.

Where to find

Mainly found in England.
