Kidney Vetch

Kidney Vetch (Anthyllis vulneraria)

 

about

Kidney Vetch is a widespread Perennial most commonly found growing locally on calcareous grassland, dry banks, sand dunes and coastal cliffs.

The bright yellow flowers are kidney shaped woolly and quite distinctive and borne in pairs on leafy stems. They are a rich source of nectar for many insects from May to September. The leaves are pairs of leaflets with a silky-hairy underside

Kidney vetch (Anthyllis vulneraria) is the sole food plant for the Larvae of Britain’s smallest butterfly, the aptly named Small Blue (Cupido minimus) found in southern and central counties

In the garden

When introducing Kidney vetch from plugs or pots, ensure good drainage if needed, by adding sharp sand to the soil in the planting hole and around the area of the base of the plant.
