The most compact panicle hydrangea, this shrub tops out at just 2 to 3′ tall and wide. Big panicles of white mophead flowers appear in early summer and age to bright pink and red tones that persist through first frost. Combined with its colorful autumn foliage, these hydrangeas make a spectacle from spring through late fall. Thick, sturdy stems help to create a neat, mounded, low-maintenance hardy shrub!
