With their large, distinctive clusters of flowers, Hydrangeas (Hydrangea spp.) are a favorite with many home gardeners.
These showy perennial shrubs thrive in rich, moist soil and shady locations, especially in warmer climates. Although they vary in their cold-hardiness depending on the species, most grow well in U.S.
Hydrangea Macrophylla and Serrata 1. Hydrangea macrophylla, or the bigleaf hydrangea, is the most commonly grown species of hydrangea, according to Auburn University College of Agriculture.
Hydrangea Paniculata 1. Often called the panicle hydrangea for its large, drooping clusters of white flowers, this hydrangea has dark green, 5-inch-long leaves that are much narrower than the bigleaf hydrangea.
Hydrangea Anomala 1. Hydrangea anomala, appropriately known as the climbing hydrangea, is the only species that has a fragrance. The plant has dark green, rounded foliage with a glossy finish.
Hydrangea Quercifolia 1. Hydrangea quercifolia is more commonly known as the oakleaf hydrangea. Unlike most other hydrangeas, it is often cultivated for its leaves, which are shaped like oak leaves and can reach lengths of 8 inches.
Hydrangea Arborescen 1. Although H. arborescens is often called the smooth hydrangea, it is not because of its foliage: The large, round leaves actually have a coarse texture and can reach lengths of 8 inches.
