Rex Begonia 'Silver', aka Painted-Leaf Begonia or Fancy-Leaf Begonia, is a lovely, small-leaved cultivar of Rex Begonia with a compact growth habit. Each leaf is covered in stunning metallic silver, with the odd green or purple spotting along the veins, and contrasting burgundy undersides. Although they can produce blooms, they are grown for their beautiful, showy foliage.
