This is a prostrate plant which is found on arable land, on tracks and waste ground. It rarely reaches much above 10cm, and bears very small (2-3mm), white flowers in dense racemes. These flowers have 4 petals, which are longer than the sepals, and 6 stamens, all of which have anthers. They are borne on stem tips and in the axils of branches, on spreading stems and flower from May to September. The leaves are light green, deeply pinnate and have coarsely toothed leaflets. The fruit is kidney-shaped and pointed above, with raised ridges. This is an annual or biennial and was probably introduced. It is found, not too commonly, mainly in coastal areas and belongs to the Brassicaceae or Cabbage family.
I first saw this wildflower at Duncannon, Co Wexford in 2011 and photographed it in 2012 at Hook Head, also in Co Wexford.
