When In Rhode Island Do Hydrangeas Bloom?

Hydrangeas bloom in Rhode Island from late spring to late fall, depending on the type of plant. They are woody flowering shrubs known for their vibrant blooms and have a distinct blooming season in the island of Nantucket. The island’s soil, temperatures, and moisture levels create an amazing array of blue and pink blossoms.

To prepare your hydrangeas for winter, remove all flowers from them in late fall or before the first frost. Plants form flower buds for the next year in mid to late summer, so regular rain throughout the year is essential. The peak bloom lasts roughly two weeks, and the length of their peak bloom depends on the type of hydrangea you are growing.

The blooming season for hydrangeas in Rhode Island typically begins in early spring and continues until mid-May. Smooth (Hydrangea arborescens) and Tree (Hydrangea paniculate) bloom on the new spring growth, and can be pruned down to 6-12 inches in late winter. The plant survives by sending up new canes, and if you have an Endless Summer, you may get some August blooms. Rhode Island blue hydrangea is the earliest to bloom in the region (early to mid-June), with large white lace-cap flowers that are attractive but have a short but stunning blooming period.

In summary, hydrangeas are woody flowering shrubs known for their vibrant blooms and have a distinct blooming season in Rhode Island. Following expert care tips and tricks can help you enjoy a yard full of blue and pink blossoms.

Why has it been a remarkable year for hydrangeas in New England?

Plants form flower buds in mid to late summer, requiring regular rain throughout the year.

Hydrangeas, native to East Asia, first appeared in North America in the early 18th century through trade and colonial expansion. They found fertile ground for growth in American gardens, with the first introductions believed to have taken place through Boston’s port. Hydrangeas come in various species and cultivars, but the Bigleaf Hydrangea (Hydrangea macrophylla) is the most iconic.

Some hydrangeas are more shade-tolerant than others, so don’t let a little shade hinder your gardening goals.
