Candy Apple Hydrangea or Hydrangea paniculata 'Candy Apple' features the same beautiful lime-green flowers as Limelight Hydrangea, but grows in a more compact form. Candy Apple Hydrangea deciduous shrubs typically grow 4 to 8 feet tall and wide in natural form. The lush, green foliage and cone-shaped lime-green flowers make for beautiful container plants as well as a focal point for gardens. The cuttings make gorgeous dried flower arrangements that you can enjoy after hydrangea bloom season has ended.
