Hydrangeas come in various varieties and cultivars, making them popular for gardeners. As a result of their widespread appeal, plant breeders have been driven to develop more stunning varieties.
The categories and characteristics of each type are described in the following list. There are numerous advantages to growing hydrangeas in the garden, and gardeners have known this for generations.
Early spring or summer brings a burst of floral and occasionally foliar interest that lasts until fall. Plants of this family are generally low-maintenance and offer a high return on investment, making them an excellent choice for beginners.
One thing that all plants require, regardless of species, is a constant supply of water for the duration of the growing season. Hydrangea derives from the Greek words Hydor, which means water, and Angus, which means jar or container.
The seed capsules’ resemblance to small Grecian water jars inspired the name’s literal translation: “water jar.” Hydrangeas, with their blooms, are classified as shrubs.
Hydrangeas may grow up to 15 feet tall, and they can easily take over a whole yard.
They can grow 25 inches or more per year till they reach maturity. A “tree” plant is expected to grow at least 3 inches wide and 13 feet tall by the time it is 4 1/4 feet tall.
Clusters of brightly colored hydrangea blossoms make them immediately identifiable. Many diverse species have the same lovely foliage and flowers, but they are all distinct.
Hydrangeas are an excellent choice for a garden plant because of their enormous and vibrant blooms. Mixing and matching the various bloom colors available in hydrangeas is easy because there are such wide varieties.

Regarding rapid growth, hydrangeas are classed as 25 inches or more per year till they reach maturity. A “tree” plant is expected to grow at least 3 inches wide and 13 feet tall by the time it is 4 1/4 feet tall.
How Much Space Does a Hydrangea Need?
Choosing a place with early sun and dappled afternoon shadow is critical when it comes to planting, according to McEnaney.
