Erinacea anthyllis, blue broom, hedgehog plant, or rushy kidney vetch, is a species of flowering plant in the legume family Fabaceae. It is native to stony mountainous places in the Pyrenees, the Mediterranean and Morocco. It is a dwarf, spiny, evergreen shrub growing to a dome shape 30 cm (12 in) tall and wide. It has dense foliage, and lilac coloured pea-like flowers in late spring and early summer. The Latin specific epithet anthyllis highlights the plant's similarity to the related kidney vetch, Anthyllis vulneraria.
