If only Cardiff Bay had a large thriving area of Kidney vetch (Anthyllis vulneraria), then we might also have a small thriving colony of Small blue butterflies, as this is their larval food plant.

Sadly, the few plants that manage to survive in the Bay are locked away behind a tall barrier of diagonal wire mesh in a tiny patch of waste ground; the fact they’re inaccessible is probably the only reason they’ve survived Cardiff Council’s ‘spray herbicide on everything’ policy of environmental (mis)management. The mesh also means the plants are very much overlooked and under-appreciated, as well as being difficult to photograph, which is a great shame, as Kidney vetch is a very attractive wildflower.
