Oakleaf Hydrangea

Highlights

There are hundreds of species of hydrangeas worldwide. Only a few are native to North America, including oakleaf hydrangeas. These gorgeous shrubs deliver both memorable leaves and long-lasting flowers. In the fall, their leaves turn to shades of copper and fiery red. Many non-native hydrangeas can be finicky and require special care—but not the oakleaf. Plant a few in sun or part-sun and enjoy beauty for years.

What are the benefits of planting an oakleaf hydrangea?

Oakleaf hydrangeas are native plants, or plants that have lived in North America for thousands (if not millions) of years. The native plants in our areas have seen and survived every blizzard, heat wave, and drought in their home area. They have the DNA and experience to thrive in our gardens. Planting native is important for many reasons, including:

1. Native plants like Oakleaf Hydrangeas give bugs, pollinators, and birds the homes and food they need to survive.
2. Native plants and trees require minimal work, water, and care to thrive (especially compared to lawns.) After being established, all Oakleaf Hydrangeas need is rain to thrive.
3. Native plants are GORGEOUS. They have been hiding in plain sight and their beauty is undeniable. Explore our library to find your faves.

Native vs. non-native hydrangeas

Hydrangeas are a go-to for landscaping. We really love them here in the U.S.; according to Penn State, 13.% of all shrubs sold in the U.S. in 2014 were hydrangeas. There are dozens of types to pick from, but the majority of the hydrangeas you see (with the round blue blooms) are native to Japan.

Non-native hydrangea care can be a pain

Martha Stewart’s non-native hydrangea recommendations include consistent moisture, checking the soil PH, and too much sun (or not enough!) On the other hand, oakleaf hydrangeas can handle periodic droughts and require no fertilizing.

Let’s see how oakleaf hydrangeas stack up against the non-natives:

Non-native hydrangeas

• Many non-native hydrangeas are from Asia
• Can require annoying extra care, including extra watering and finicky specialty fertilizers to get blue flowers
• Many are sterile, so they provide no nectar or pollen for native pollinators

Native oakleaf hydrangea

• Oakleaf hydrangeas have grown for thousands of years in what is now the southeastern US.
• Once they are established, oakleaf hydrangeas thrive with just rain
• Pollen-filled flowers offer lots of food for pollinators

Oakleaf hydrangeas throughout the seasons

Oakleaf hydrangeas transform themselves throughout the year. It is rewarding to fill our yards and parks with plants that change with the seasons. Their changes help enliven and surprise us, offering new vistas outside our windows every few months (as opposed to a boring boxwood evergreen shrub, which sits forever in its single, boring state.)

Spring

In the spring, bright green shoots emerge from the tips of branches. These first leaves look like green flowers! The leaves emerge from the cone over the spring, changing to a vibrant green.

Summer

Oakleaf hydrangea flowers last for MONTHS. After the leaves come the large, cone-shaped flowers. The blooms are large—bigger than your hand. Each provides lots of space for multiple pollinators.

Fall

In the fall, oakleaf hydrangea leaves turn into fiery shades of copper and red. Because their leaves are so large, the effect is stunning. Plant them alongside some blue-purple asters for a perfect fall pairing.

Where to plant oakleaf hydrangea

In the wild, oakleaf hydrangeas are often found along streambeds. They like moist, rich soil like you’d find in a woodland, but once they’re established, they’re very hardy and surprisingly drought-tolerant.

Plant nerd fact

Hydrangeas have fake flowers

Look closely at this oakleaf hydrangea flower in bloom:

Notice that there are two different shapes: white flowers and tiny, green, bead-like orbs hidden underneath.

The white petals are fake flowers. These petals are actually leaves shaped to look like petals. They have no pollen. (Leaves that mimic petals are called bracts; the bright red “flowers” on holiday favorite pointsettas are bracts, too!)

Those dozens of tiny green bead-like shapes are the actual flowers. They produce pollen and, when fertilized, turn into seeds. The bracts are there to attract pollinators, but the real treat is hidden below.

They can grow in many soil types, including sand and clay, but they do not like to be waterlogged and will struggle in very wet spots.

In northern areas, they will happily grow in full sun to part shade, and will bloom better with more sun. In the South, they appreciate more shade and can light up dark corners of the garden.

Here’s a few ideas for where to plant oakleaf hydrangea:

• As a foundation plant along the front of your house
• As a four-season centerpiece in a border or island
• Against a wall or in front of evergreens, to appreciate their winter foliage
• As an informal hedge
• In the South, under shady trees to brighten up dark spots of the garden
• In woodland gardens or naturalized areas, under trees or along forest edges

How big does oakleaf hydrangea get?

Oakleaf hydrangea is a slow-growing but large shrub. It will grow 4-8 feet tall and 4-10 feet wide.

If that’s too big for your yard, some cultivars are smaller, such as ‘Pee Wee,’ which only grows to 4 feet by 3 feet. Thankfully, these cultivars include pollen-filled flowers.

Where can I buy oakleaf hydrangeas?

Hydrangeas are generally easy to find at almost any nursery in North America. Sadly, most of the hydrangeas you’ll see are the non-native variety.

What are good pairings for oakleaf hydrangeas?

These shrubs are best paired with other native plants that like similar partial sunlight. Trees like Sweetbay Magnolia and Tulip Poplar, shrubs like Mountain Laurel and Ninebark, and flowers like Aster and Bee Balm are great pairings.

Now you’re ready to plant an oakleaf hydrangea (or a few!) by using these tips and inspiration. Hydrangeas are known for being stunning yard additions—but only the oakleaf hydrangea is native to North America. Spend a morning planting this native shrub and watch it return decades of beauty, year-round. Want to meet some other native hydrangeas? Explore our Beginner’s Guide to Native Hydrangeas.
