Hydrangea Annual Or Perennial, Hydrangeas are perennial woody ornamental shrubs as they live for many years, provided you choose the correct type of hydrangea for your growing environment.,
Hydrangeas are perennial shrubs; this means they come back every year. That said, in some cases when grown in greenhouses or sold off as gift plants, they grow as annuals because they don't come back after harvesting the bloom. But some hydrangeas are indeed root-hardy.16-Jul-2021
Yes, hydrangeas will come back every year as long as they do not die over the winter. Some gift hydrangeas are not bred to be very winter hardy though. So sometimes hydraneas will not survive the winter. But in general, most hydrangeas will come back every year.
