|This annual is grown for its attractive foliage and mounding form. 'White Diamond' has grayish-white, deeply dissected leaves and grows 12-16" tall and to 12" wide.
Can over winter and act like a perennial in warmer areas, or if mulched heavily. Flowers are mustard-yellow, held in corymbs, and are produced in the second year.
Shear or pinch back plants if they become leggy. Tolerant of many soils, prefers full sun and well drained site. An excellent foil between brightly colored bedding plants. Often used as an edging or border plant.
