Types of Hydrangea Bushes (with Pictures): Identification and Growing Guide
Hydrangeas are beautiful bushy deciduous shrubs with large, colorful, showy flowers and large bright to dark green leaves. Hydrangea flowers bloom in shades of blue, lavender, white, pink, red, green, and purple. The bigleaf hydrangea (Hydrangea macrophylla) is the most popular of these flowering bushes. Other types of hydrangea bushes include smooth hydrangeas, oakleaf hydrangeas, climbing hydrangeas, panicle hydrangeas, and mountain hydrangeas.
There are hydrangea varieties suitable for most garden landscapes. If you have a small, compact garden, then a dwarf hydrangea variety is ideal. You will even find a small, miniature hydrangea if you want a patio plant and grow hydrangea flowers in a container.
A characteristic of hydrangea flowers is that their color can depend on the type of soil. For example, a blue hydrangea may have showy lilac or light purple flowers in acidic soil, but in alkaline soil, the mophead flower will be pinkish. With proper care, your beautiful hydrangea bush can flower throughout the summer until the fall.
This article is a guide to the many different hydrangea varieties and cultivars suitable for your garden. Descriptions of these large leafy shrubs and pictures of hydrangea flowers will help choose the best hydrangea for your garden.
Hydrangea Varieties for Landscaping — Overview
Hydrangeas are easy to grow multi-stemmed perennial deciduous shrubs with colorful flowers and dense leafy foliage. Most hydrangea cultivars thrive in USDA zones 3 through 9. Depending on the cultivar, hydrangea bushes grow best in partial shade. However, some hydrangea flowers flourish in full sun.
The advantage of growing hydrangea shrubs in your garden is their versatility. Hydrangeas thrive in almost any type of soil, tolerate wind, and grow well in coastal regions.
How Big Do Hydrangea Get?
Most hydrangeas are large shrubs that grow between 3 and 5 ft. (1 – 1.5 m) high. The tallest types of hydrangeas are climbing hydrangeas (Hydrangea anomala) that reach up to 50 ft. (15 m) tall if they have enough support. Dwarf hydrangeas varieties are typically 2 or 3 feet (0.6 – 1 m) tall.
Hydrangeas usually have a similar spread to their height. This growth feature of hydrangeas makes it easy to plan to grow these stunning flowers in your garden.
Hydrangea Flowers
Hydrangea flowers are long-lasting, showy blooms that have various shapes and sizes. The stunning flower heads can be rounded domes, flat lacy clusters, pointed cone shapes, or huge ball-like flowers.
Here are the types of hydrangea flowers:
Mophead hydrangea flowers are large, showy blossoms with rounded, dome-shaped clusters. Also called pom-pom hydrangeas, these popular garden flowers can be as large as a dinner plate. Mophead hydrangea flowers can measure between 4” and 14” (10 – 35 cm) across. Mophead flowers grow on bigleaf (French) hydrangeas and bloom from late spring until midsummer. The flower color is blue in acidic soil and pink in alkaline soil.
Lacecap hydrangea flowers are unusual flowers growing in flat clusters on bigleaf hydrangeas. The flower heads bloom during summer until fall. The hydrangea flowers consist of small floret clusters in the center and a ring of 4- or 5-petaled flowers around the edge. The flower color is blue in acidic soil and pink in alkaline soil.
Panicle hydrangea flowers are cone-shaped flower heads that can be white, vibrant pink, pastel pinkish-red, or green. Panicle cone hydrangea flowers bloom from late spring until the frost.
Snowball hydrangea flowers are stunning globe-like white flowers that grow up to 12” (30 cm) in diameter.
Hydrangea Leaves
Hydrangea bushes are known for their large leathery pointed ovate leaves. The shape and form of hydrangea leaves depend on the hydrangea type and cultivar.
Here are the types of hydrangea leaves:
Bigleaf hydrangeas leaves are thick and glossy with serrated margins and grow up to 8” (20 cm) long.
Panicle hydrangeas have narrow, dark-green fuzzy leaves that grow up to 5” (12 cm) long.
Smooth hydrangea leaves have a coarse texture and medium to dark green color. Leaves on smooth hydrangea bushes grow up to 8” (20 cm) long.
Oakleaf hydrangea leaves. As the name suggests, these hydrangea leaves look like oak leaves. The dull grayish-green summer foliage turns a spectacular red or orange in the fall.
Climbing hydrangea leaves are aromatic leaves that are a rounded to ovate shape with toothed edges. From the different hydrangeas varieties, climbing hydrangea leaves are the smallest, measuring between 2” and 4” (5 – 10 cm) long.
Types of Hydrangea Bushes – Overview
Hydrangeas are classified into different species depending on the type of flower, leaves, and growth pattern.
Here are the six varieties of hydrangea bushes:
- Bigleaf Hydrangea (Hydrangea macrophylla)—Also called mophead hydrangea, French hydrangea, or pom-pom hydrangea. These hydrangeas have large colorful dome-shaped flowers or lacecap flowers. Flower color varies depending on the soil pH. These popular large-leaved hydrangeas grow 4 ft. (1.2 m) tall and wide.
- Oakleaf hydrangea (Hydrangea quercifolia)—Cylindrical flower clusters that grow 6” to 12” (15 – 30 cm) tall. Colors are typically white or pink and are not affected by pH levels in the soil. Oakleaf hydrangeas grow between 3 and 12 ft. (1 – 3.6 m) tall.
- Panicle hydrangea (Hydrangea paniculata)—Cone-shaped hydrangea flower clusters that are typically white and light green. These hydrangea shrubs grow between 3 and 16 ft. (1 – 5 m) tall and 8 ft. (2.5 m) wide.
- Smooth hydrangea (Hydrangea arborescens)—These hydrangea shrubs usually have huge ball-like flowers that bloom from May until July. The hydrangea bush grows 10 ft. (3 m) tall and 6 ft. (1.8 m) wide.
- Climbing hydrangea (Hydrangea petiolaris)—Flowers on climbing hydrangeas look like flat-topped corymbs measuring between 6” to 10” (15 – 25 cm) wide. These plants are the tallest hydrangea varieties. The shrub grows up to 50 ft. (15 m) tall and 6 ft. (1.8 m) wide.
- Mountain hydrangea (Hydrangea serrata)—Mountain hydrangeas are identified by their lacy pink flower heads that grow on old wood. Like bigleaf hydrangeas, soil pH affects the flower colors. The shrub grows 4 ft. (1.2 m) tall and wide.
Planting Hydrangeas
Growing hydrangea shrubs that flower throughout the summer depends on growing them in the right place and the correct soil type. Here is a short guide to planting hydrangea bushes in a garden landscape.
When to plant hydrangeas: Plant hydrangea bushes after the last spring frost, or in fall before the first frost to give the flowering plants a chance to develop roots before the soil becomes really cold.
Where to plant hydrangeas: The best location to plant hydrangeas is where they get partial sun. Ideally, sun in the morning and shade in the afternoon. Plant the hydrangea in fertile soil that stays moist but drains well.
How to plant hydrangeas: Dig a hole that is two or three times the size of the root ball. Plant the hydrangea so that it’s higher than it was in the nursery pot. Fill the hole with organically rich soil, press down, and water thoroughly.
How to plant hydrangeas in pots: Plant hydrangeas in a suitable container filled with a loose potting mix that has excellent drainage.
Transplanting hydrangeas: You can transplant hydrangeas in the fall before the ground freezes. Dig a large hole in the new location where there is afternoon shade. Dig around the hydrangea bush to free the root ball. With the help of someone else, pry the large shrub from the ground. Replant in its new location.
How to Care for Hydrangea Shrubs
Grow hydrangea bushes in fertile soil that is amended with plenty of organic matter. Water hydrangeas enough so that the ground is moist but never too soggy. Use a slow-release fertilizer with an NPK rating of 10-10-10. Deadhead hydrangea flowers after blooming and prune dead stems to keep the plant tidy.
