Small, mounding, aromatic Mediterranean shrubs that flower in summer with small yellow, button-like flowers. Prune in spring after flowering to maintain appearance. Two widely available species are lavender cotton (S. chamaecyparissus, 1-2’ x 2-3’) with gray-green foliage, and S. rosmarinifolia (1-2’ x 2-3’) with green foliage that resembles rosemary.
