This introduced plant from Southern Europe looks very much lik e Brassica nigra (Black Mustard) although in Spring many yellow crucifers do look very similar. The seed pods visible later in the season are pressed against the main stem but in the end "beak" of each pod is a seed in H. incana not visible in B. nigra. The distribution isn't that wide spread in the British Isles. There are occasional sites in Ireland, virtually none in Scotland and the majority of sites are in South Wales and the south east of England.
