The Magnificent Six: Main Types of Hydrangeas
Of the 49 known hydrangea species, six are primarily cultivated in North America. Each type has its own unique characteristics, care requirements, and growth habits. Let’s explore these hydrangea varieties in detail:
1. Bigleaf Hydrangeas (Hydrangea macrophylla)
Bigleaf hydrangeas, also known as French hydrangeas, are perhaps the most popular and recognizable type. They’re divided into two subcategories:
- Mophead: Features large, rounded flower clusters
- Lacecap: Displays flat flower heads with tiny fertile flowers in the center, surrounded by showy sterile flowers

Bigleaf hydrangeas are renowned for their ability to change flower color based on soil pH. In acidic soil (pH below 6.0), flowers tend to be blue, while alkaline soil (pH above 7.0) produces pink blooms. These old-wood bloomers prefer partial shade and well-draining, moist soil.
2. Panicle Hydrangeas (Hydrangea paniculata)
Panicle hydrangeas are known for their cone-shaped flower clusters and their ability to tolerate more sun than other varieties. They bloom on new wood, making them more cold-hardy and easier to prune.

Popular varieties include:

- ‘Quick Fire’: Early bloomer with white flowers that turn deep pink
- ‘Little Lime’: A compact version of ‘Limelight’, perfect for smaller spaces
3. Smooth Hydrangeas (Hydrangea arborescens)
Native to North America, smooth hydrangeas are known for their large, round flower clusters and their ability to bloom on new wood. They’re incredibly hardy and can thrive in colder climates.
Popular varieties include:
- ‘Annabelle’: Features enormous white flower heads
- ‘Incrediball’: An improved version of ‘Annabelle’ with stronger stems
- ‘Invincibelle Spirit’: A pink-flowering cultivar
4. Oakleaf Hydrangeas (Hydrangea quercifolia)
Oakleaf hydrangeas are prized for their distinctive foliage that resembles oak leaves. They offer year-round interest with their summer blooms, fall color, and exfoliating bark in winter.
These hydrangeas prefer partial shade and well-draining soil. They bloom on old wood, so avoid pruning in late summer or fall.
5. Mountain Hydrangeas (Hydrangea serrata)
Mountain hydrangeas are similar to bigleaf hydrangeas but with smaller leaves and flowers. They’re more cold-hardy and often bloom earlier.

Climbing hydrangeas prefer partial shade and well-draining soil. They’re slow to establish but become vigorous growers once settled.
Choosing the Right Hydrangea for Your Garden
When selecting a hydrangea for your garden, consider the following factors:
- Sun exposure: Some hydrangeas thrive in full sun, while others prefer shade
- Soil type and pH: This affects both growth and flower color for some varieties
- Climate: Choose varieties that are hardy in your USDA zone
- Space: Consider the mature size of the plant when planning your garden
Caring for Your Hydrangeas
To keep your hydrangeas healthy and blooming beautifully:
- Water deeply and regularly, especially during dry spells
- Mulch around the base to retain moisture and suppress weeds
- Fertilize in early spring with a balanced, slow-release fertilizer
- Prune at the right time based on your hydrangea type (old wood vs. new wood bloomers)
- Protect from extreme weather conditions, especially winter winds and late spring frosts
