Oakleaf Hydrangea Care Guide for Beautiful Blooms
Oakleaf hydrangeas are some of the most interesting flowering shrubs you can add to a landscape. Their large, deeply lobed leaves resemble oak leaves, which is how they earned their name. While many hydrangeas are grown primarily for their blooms, oakleaf hydrangeas provide beauty through several seasons. They produce cone-shaped flower clusters in late spring and summer, colorful foliage in the fall and attractive peeling bark during the winter.
Oakleaf hydrangeas are also native to the southeastern United States, making them an excellent choice for woodland gardens, natural landscapes and partially shaded areas. Before planting one, it is important to choose the right variety because mature sizes can vary greatly.
How Much Space Do Oakleaf Hydrangeas Need?
A standard oakleaf hydrangea can grow approximately 6 to 8 feet tall and equally wide. Some varieties can become even larger under ideal conditions. These are not shrubs that should be squeezed into a tiny space beside a walkway unless you enjoy pruning every time you step outside.
When planting an oakleaf hydrangea, consider its mature width rather than the size of the small container you bring home from the nursery. Allow enough room for air circulation and natural growth. Smaller varieties are available for tight spaces, foundation plantings and compact gardens.
Popular Oakleaf Hydrangea Varieties
Standard Oakleaf Hydrangea
The traditional oakleaf hydrangea grows approximately 6 to 8 feet tall and 6 to 8 feet wide. Its white cone-shaped blooms gradually age to shades of pink and purplish pink. The large leaves often turn burgundy, red or purple during the fall.
Alice Oakleaf Hydrangea
Alice is a large variety that typically reaches 5 to 8 feet tall and wide. It produces large white flower clusters that slowly fade to pink. Alice is a great choice for a large landscape bed, woodland edge or informal hedge.
Snow Queen Oakleaf Hydrangea
Snow Queen usually grows about 6 feet tall and up to 8 feet wide. It has upright white flower clusters that create a clean, elegant appearance. This variety works well as a specimen shrub or as part of a mixed flowering-shrub border.
Ruby Slippers Oakleaf Hydrangea
Ruby Slippers is a compact favorite that grows approximately 3 to 4 feet tall and 3 to 5 feet wide. Its blooms begin white and gradually turn a deep ruby-red color. This variety is ideal for homeowners who want dramatic color without planting a large shrub.
Pee Wee Oakleaf Hydrangea
Pee Wee is another compact option. It typically grows about 3 to 4 feet tall and approximately 3 feet wide. Its flowers open white and fade to pink. This is a good choice near patios, entryways and smaller garden beds.
Little Honey Oakleaf Hydrangea
Little Honey grows around 3 to 4 feet tall and 4 to 5 feet wide. It is especially valued for its golden-yellow spring foliage, which matures to a chartreuse color in summer. It produces white blooms and adds a bright pop of color to partially shaded areas.
Gatsby Gal Oakleaf Hydrangea
Gatsby Gal grows about 5 to 6 feet tall and wide. It is slightly more compact than some larger varieties but still produces impressive white flower clusters. The blooms may develop pink tones as they age.
Gatsby Pink Oakleaf Hydrangea
Gatsby Pink grows approximately 6 to 8 feet tall and wide. Its white blooms quickly transition to a rich pink color, providing months of interest. The foliage turns burgundy-red in fall, making this a strong choice for a larger landscape focal point.
Gatsby Moon Oakleaf Hydrangea
Gatsby Moon reaches approximately 6 to 8 feet tall and wide. Its tightly packed double white flowers have a quilted appearance and gradually age to green. This variety has a fuller bloom structure than a traditional oakleaf hydrangea.
Gatsby Star Oakleaf Hydrangea
Gatsby Star also grows approximately 6 to 8 feet tall and wide. Its double white blooms have pointed petals, giving each flower cluster a lacy, star-shaped appearance. The flowers may develop pink tones as the season progresses.
Gatsby Glow Ball Oakleaf Hydrangea
Gatsby Glow Ball is a smaller variety that grows about 3 to 4 feet tall and wide. Its rounded flower clusters are bright white with a soft green tint. It is a useful option when you want an oakleaf hydrangea in a more compact garden space.
Where to Plant Oakleaf Hydrangeas
Oakleaf hydrangeas grow well in full sun to partial shade, although they generally appreciate some protection from harsh afternoon sun in hotter climates. A location with morning sun and afternoon shade is often ideal.
Choose soil that is rich in organic matter, moist and well drained. Avoid areas where water remains puddled after heavy rain. A layer of mulch around the base of the shrub helps retain moisture and keep the roots cooler during the summer. Keep the mulch a few inches away from the stems to reduce the risk of rot.
When and How to Prune Oakleaf Hydrangeas
Oakleaf hydrangeas bloom on old wood. This means that next year’s flower buds develop on stems produced during the previous growing season. If you cut the shrub back hard in fall, winter or early spring, you may remove most of the upcoming blooms.
Prune oakleaf hydrangeas only when necessary. The best time to shape the plant or reduce its size is immediately after the flowers begin to fade. Remove dead, damaged or crossing branches first. Then trim lightly to maintain the shrub’s natural form.
Avoid cutting the entire shrub down to the ground unless you are willing to sacrifice blooms while it recovers. Oakleaf hydrangeas look best when allowed to grow with a relaxed, natural shape.
How to Fertilize Oakleaf Hydrangeas
Oakleaf hydrangeas do not require heavy fertilization. Too much fertilizer, especially a high-nitrogen product, can produce lots of green leaves with fewer flowers.
Apply a balanced, slow-release fertilizer in spring according to the instructions on the product label. Compost can also be added around the root zone to improve the soil gradually. If your oakleaf hydrangea is growing well and blooming reliably, there is no need to overdo it. More fertilizer is not always better.
Final Thoughts
Oakleaf hydrangeas are excellent shrubs for gardeners who want more than a few weeks of flowers. Their white, pink or ruby-toned blooms are beautiful, but their colorful fall leaves and peeling winter bark make them valuable throughout the year.
The key is choosing the correct variety for your available space. A compact Ruby Slippers, Pee Wee or Gatsby Glow Ball may be perfect near a patio, while a larger Alice, Snow Queen or Gatsby Pink can fill an open landscape bed beautifully. Give your oakleaf hydrangea enough room to grow, prune only after flowering and fertilize lightly in spring. With the right care, it can become one of the most impressive shrubs in your landscape.
