The hydrangea blooming season depends upon the type and cultivar as well as your planting zone. Most new growth hydrangeas put on buds in early summer to bloom in the following spring, summer and early fall seasons. In hot climates, hydrangeas may stop blooming in the heat of summer, but will rebloom in the fall.

What season can you buy hydrangeas?

Hydrangeas are often thought of as a southern plant and in warm southern climates they typically bloom from May to July. However, many hydrangea species are hardy enough to tolerate northern climates and blooms may come as late as August and September in cooler areas.

Do hydrangeas flower all year?

Growing hydrangeas is a no-brainer if you want a garden with year-round interest. They flower from mid-summer until the end of the year.
