Kidney vetch Anthyllis vulneraria
“A wealth of heather, kidney-vetch and squillsOver these long-defended Cornish hills.”- John Betjeman, ‘Cornish Cliffs’
Kidney vetch’s clusters of small yellow flowers on little woolly bases, rapidly colonise bare ground on sand dunes, chalk grassland and cliffs, wherever they get the opportunity.
