Overview

Bird's-foot Trefoil is one of the most important wildflowers of the Sefton Coast dune grassland — a key nectar and pollen source for bumblebees, solitary bees, Six-spot Burnet Moths and Common Blue butterflies (whose larvae feed on it). The yellow-and-orange flowers form small clusters, and the ripe seed pods splay out like a bird's foot, giving the plant its name. Known as 'eggs and bacon' from the yellow and orange combination. One of the first flowers to bloom on new dune grassland.

Frequently Asked Questions

Why is Bird's-foot Trefoil so important for the Common Blue butterfly?

Bird's-foot Trefoil is the primary larval foodplant of the Common Blue butterfly on the Sefton Coast dunes. Wherever this plant grows in good quantity, Common Blue populations flourish. The plant also provides nectar for adult butterflies, making it doubly important. Managing dune grassland to maintain Bird's-foot Trefoil directly supports Common Blue populations.
