Coronilla valentina, the shrubby scorpion-vetch,[2] scorpion vetch or bastard senna,[3] is a species of flowering plant in the genus Coronilla of the legume family Fabaceae, native to the Mediterranean Basin, and introduced into Kenya and the United States.[1] It is an evergreen shrub growing to 80 cm (31 in) tall and wide, with pea-like foliage and fragrant, brilliant yellow flowers in spring and summer, followed by slender pods.[4] Linnaeus observed that the flowers, remarkably fragrant in the daytime, are almost scentless at night.[5]
