Alyssum spinosum, now Hormathophylla spinosa (spiny madwort) is a species of flowering subshrub in the genus Alyssum of the family Brassicaceae, native to open rocky sites in south-eastern France and southern Spain. It forms a compact mound up to 30 cm in height. Dense spiny branches of tiny, toothed grey-green leaves bear racemes of white flowers at the tips in early summer.[1]

It is especially cultivated in rock gardens. The cultivar A. spinosum 'Roseum',[2] with pink flowers, has gained the Royal Horticultural Society's Award of Garden Merit.
