How To Identify Your Hydrangeas

Laura from Garden Answer shows us the different types of hydrangeas and what makes each so special! Learn bloom time, pruning habits and some great varieties!

Hydrangeas come in six main groups, and each one offers a distinct bloom shape, growth habit, and pruning schedule. Knowing your type makes care much easier and helps you choose varieties that thrive in New England gardens.

Bigleaf hydrangeas (Hydrangea macrophylla) produce large mophead or lacecap blooms in shades of blue, pink, purple, or white. They bloom on old wood, though the Let’s Dance series blooms on both.

Mountain hydrangeas (Hydrangea serrata) look similar to lacecap bigleaf types but offer better winter bud hardiness. Many gardeners in colder areas choose the Tough Stuff series for reliable blooms on old and new wood.

Panicle hydrangeas (Hydrangea paniculata) form tall, cone-shaped clusters that shift from white or green to pink and red. They bloom on new wood and tolerate full sun, making them one of the easiest and hardiest groups.

Smooth hydrangeas (Hydrangea arborescens) include favorites like Annabelle. These shrubs bloom on new wood with large, round flower heads and tolerate very cold climates. They are also native to the United States.

Oakleaf hydrangeas (Hydrangea quercifolia) create cone-shaped blooms that age from white to pink to tan. Their deeply lobed leaves make them easy to identify. They bloom on old wood and offer beautiful fall color.

Climbing hydrangeas include the true hydrangea (Hydrangea petiolaris) and the similar false hydrangea (Schizophragma). Both climb by aerial roots and produce elegant lacecap-style blooms.

Understanding your hydrangea helps you prune it correctly and predict its bloom time. Visit us in-store if you’d like help identifying your plant or choosing a new hydrangea for your garden.
