Easy to care for
Hydrangeas are generally worry-free, though some types need periodic pruning. "Here's a group of plants that don't have insect or disease problems, so for the little care you give them, the rewards are great," says Ed Hasselkus, horticulture professor emeritus at the University of Wisconsin-Madison.
It's important to choose a hydrangea that's appropriate for your Zone and landscape. The next slides show four main types of hydrangeas: bigleaf (H. macrophylla), panicle (H. paniculata), smooth (H. arborescens) and oakleaf (H. quercifolia).
