The oakleaf hydrangea (Hydrangea quercifolia) is a flowering deciduous shrub with huge clusters of flowers and large unique leaves that resemble oak lobes. (In Latin, quercifolia means “oakleaf”). This shrub is appreciated for its long-lasting blossoms, which start out white and then turn purplish pink. This multi-stemmed shrub, which grows 4 to 8 feet tall and has a rounded upright growth style, spreads via suckering.
What does an oak leaf hydrangea look like in winter?
Oakleaf hydrangeas (Hydrangea quercifolia), which are native to the southeast, are lovely all year. Spring and early summer are the best times to see these hydrangea plants in bloom. When the panicle blooms are young, they are greenish white, but as they mature, they take on delicate colors of pink and brown. When new flowers stop blooming, the blossoms stay on the plant and mature into gorgeous blooms.
The lobed leaves can grow to be as long as 12 inches (31 cm). They are bright green in the spring and fall, but as autumn progresses to winter, they become vivid colours of crimson and orange. In the winter, the bark peels back, revealing the dark layer beneath, making them a charming and fascinating shrub.
These characteristics make cultivating oakleaf hydrangeas in your garden a delight. You’ll discover that caring for oakleaf hydrangeas is pretty simple.
How much sun does an oakleaf hydrangea need?
To ask which of my plants is my favorite is like asking which of my children is my fave! A difficult topic to answer, but since I’m not in danger of hurting sensitive young egos, I’d have to say the oakleaf hydrangea is one of my favorites (Hydrangea quercifolia). The reason for this is that this is a plant that has four distinct seasons of appeal. That appeals to me since it saves me time, energy, and money. It rewards me in the spring, summer, fall, and winter once it has established.
Hydrangea quercifolia is a shrub that grows to be around six to eight feet tall, with a maximum height of ten to twelve feet. The huge, dark green leaves have silvery undersides and resemble the Northern Red Oak, from which it receives its popular name. It can be grown in zones 5 through 9.
Cone-shaped flowers can grow up to a foot in length. The blossoms start out white, then acquire a pink blush before turning red as the seasons pass. Single or double florets might be found.
Although the spring and summer are lovely and lush, I am looking forward to the warm days and cool nights of October and November, when the flowers change red and the foliage takes on a variety of yellow, orange, red, brown, and burgundy hues. In protected areas, the leaves last for a long time before falling to reveal an uneven branching structure of cinnamon-colored peeling bark. The contrast against a snowy white bedspread is breathtaking.
Oakleaf hydrangeas thrive in hotter climates, but they like some afternoon shade. It can be grown in full sun in its northern range. The more sun exposure you get, the more flowers you’ll receive, and the more stunning the fall color will be.
This shrub can survive drier soil than its mophead relatives, but not wet feet. Plant it in acidic, wet, well-drained soil supplemented with compost or other organic matter. It can be used as a specimen feature in the landscape or as a mass planting in shaded wooded regions.
Pruning is rarely essential, although it should be done after the flowers have faded and before August. Late summer and early fall are the best times to plant flower buds for the next year. By simply snipping off old flowers, you can “deadhead” them at any time. I like to leave the blossoms on the plant throughout the winter months so that I may enjoy them.
You can cut longer stems for flower arrangements before August if you’re cutting blossoms for arrangements. After that, only remove short stems to avoid losing next year’s blooms.
Oakleaf hydrangeas are generally pest and disease free. This is another bonus in my eyes because it means that plants will look and perform their best all year long without the need of chemicals (always a last resort in my book).
The double flowered variety ‘Snowflake’ is arguably the most popular. Its creamy white blossoms can reach a length of a foot.
In the spring, the foliage of ‘Little Honey’ turns golden, then chartreuse, then green, with a gorgeous burgundy red fall color.
Oakleaf hydrangeas are a perennial favorite in my yard. They’re lovely all year with stunning leaves, exquisite flowers, and fascinating bark, and they’re hardy in many regions of the country. They’re pest and disease resistant, bloom in the shade, and are very little maintenance. What more could we expect of a plant for our landscapes and gardens?
Do oakleaf hydrangeas lose leaves in winter?
Hydrangeas are shrubs whose name comes from the Greek words for water (hydor) and vessel (angos), owing to their love of water and the shape of their seed pods, respectively. Hydrangeas are rarely recommended by Master Gardeners in Sonoma County because these strong, shade-loving shrubs with huge, dramatic blooms are better suited to locations with humid air and summer rains. One prominent exception is Hydrangea quercifolia, also known as the oakleaf hydrangea. It not only thrives in our climate, but it also makes a beautiful garden specimen, unlike the mophead and lacecap species. This is the only hydrangea on our list of Sonoma County’s Recommended Plants.
H. quercifolia is called after its deeply lobed leaves, which resemble those of the northern red oak. It is native to the Southeastern United States (Quercus rubra). Other hydrangeas’ leaves aren’t lobed, and the differences don’t end there. H. quercifolia leaves are also thick, coarse, sparsely serrated, and bristling with microscopic hairs on the undersides. Because of its thickness and pubescence (hairiness), it is the only hydrangea that can comfortably cohabit in our gardens with low-water Mediterranean and California native plants.
Oakleaf hydrangeas reach a mature height of 6-7 feet and a width of 7-8 feet, with a charming mounding habit that is less stylized than their spherical, more formal cousins in the genus. They not only require less water than other members of the genus, but they can also thrive in a variety of light conditions, from full sun to full shade, with dappled shade being optimal. Plants require more shade in the interior; the closer they are to the coast, the more light they can withstand.
There are no known disease or pest problems with H. quercifolia, and it grows slowly compared to other hydrangeas. As a result, it is a well-behaved garden citizen who does not require excessive care or water. All portions of the hydrangea, like those of other hydrangeas, are slightly poisonous if eaten.
Oakleaf hydrangea is known for its white, conical summer blossoms that can grow to be nearly a foot long. But it doesn’t stop there. Oakleaf hydrangea foliage takes on a fall coat of gorgeous, dramatic color, ranging from crimson to purple to bronze, as many summer-flowering shrubs wither and drop their leaves.
Although it is technically deciduous, it retains its leaves until early winter. The naked shrub shows off its rusty, peeling branches and stems when they fall. The shredded, cinnamon-colored bark of older stems, reminiscent of manzanita and Arbutus, adds winter appeal. New growth emerges in the spring, with a stunning color and texture and soft, silky hairs.
H. quercifolia can be used as a single specimen, in small groups, or as a landscape border.
It’s also used in mass plantings in some large gardens. There are identified types that are supposed to boost bloom size and shape while also producing larger plantssome reaching 15 feet in heightand should be picked with caution. ‘Snowflake’ is a popular choice, but the flowers are a touch heavy; ‘Pee Wee’ and ‘Sikes Dwarf’, both in the 4-6 ft. range, are recommended for smaller gardens. ‘Munchkin’ stays at a height of 3 feet and a width of 3 feet.
Is oakleaf hydrangea a panicle hydrangea?
The oakleaf hydrangea gets its name from the shape of its foliage, which resembles oak tree leaves. Hydrangea quercifolia, its scientific name, is derived from the Latin word “quercifolia,” which literally means “oakleaf.”
The oakleaf hydrangea leaves not only resemble oak tree leaves, but they also turn color in the fall, making it the only type of hydrangea that does so. Their leaves range in color from golden orange to bright crimson to deep mahogany, making them one of the most appealing shrubs for your autumn landscape.
One of the few hydrangeas native to the United States is the oakleaf hydrangea. The smooth hydrangea is the only other hydrangea that is endemic to the United States. The oakleaf hydrangea has white cone-shaped flower heads that are similar to panicle hydrangeas. It comes in two varieties: single bloom and double blossom. Its flowers, like those of the panicle hydrangea, will turn pink as the plant matures.
The oakleaf hydrangea is tougher than its cousins and can endure a wider range of climate conditions than most bigleaf hydrangeas. Oakleaf hydrangeas are more winter resistant and can withstand drier conditions. These oakleaf hydrangeas, unlike mopheads, require drier, well-drained soil because they are susceptible to waterlogging.
Because of its long-term benefits, the oakleaf hydrangea is a popular choice for gardens. Their flowers appear in the early summer and continue until the end of the season. When autumn arrives, their leaves take the stage, becoming a vibrant orange and scarlet color. Avoid growing them in deep shade in your yard since too much shade may cause their fall foliage hues to fade. Hardiness zones 5 through 9 are ideal for oakleaf hydrangeas.
Is oakleaf hydrangea a panicle?
If the macrophylla hydrangea is the Diva Queen of the garden, I’d say the oakleaf hydrangea is the King.
Oakleaf hydrangea, Hydrangea quercifolia, is a towering shrub that can grow fairly large over time. Most can reach a height of 6 to 8 feet and a width of 6 feet or more. Some plants, like as Ruby Slippers, have been bred to be dwarf-sized (see below).
The coarse-textured, oakleaf-shaped leaves of this shrub are larger (8+ inches long) than any of the other hydrangea species, giving it a king-like aspect. Oak is called “Quercus” in botanical latin, hence oakleaf hydrangea is Hydrangea quercifolia.
The creamy conical formed panicles can be small (4 inches) to big (12 inches), single or double florets, and tightly packed or loosely held florets, depending on the cultivar.
In my yard, oakleaf hydrangeas bloom sooner (in May) than other hydrangea varieties, and I notice bees and other pollinators swarming about the flowers.
What side of house do you plant hydrangeas?
The north-facing side of your home, regardless of where you live in the country, receives very little sunlight. This, combined with the fact that a north side garden is exposed to north winds, makes selecting the proper plants for a landscaping project more difficult. Fortunately, there are a variety of plants that will grow in these conditions while also adding beauty and value to your home.
When should you plant oakleaf hydrangeas?
Oakleaf hydrangeas can be produced from cuttings from established shrubs, but they’re more commonly found in three-gallon pots at your local garden center, which can be put right into your yard, according to Zawojski. Planting should be done in the spring, early summer, or early to late fall, according to him. “Do not plant bushes during periods of extreme heat, such as July and August, or January and February,” he advises.
Where is the best place to plant an oakleaf hydrangea?
Hydrangea Oakleaf Care Plant this shrub in full sun or partial shade, in a slightly acidic, rich, well-draining soil. It prefers moist soil, therefore a thick layer of mulch over the root zone will assist keep the moisture in the soil.
Should I cut back my oakleaf hydrangea?
Soil Oakleaf hydrangea grows best in moist, organic, fertile, well-drained, slightly acidic soil with a pH of 5.06.5. It is drought resilient once planted, but it does benefit from water in extremely dry conditions. It’s critical to have good drainage. Although the plant prefers damp soil, wet feet are not an option.
Full to moderate shade is fine for this shrub.
It does, however, perform better when exposed to the sun for at least a full day or more, resulting in a richer floral show, stronger stems, and more beautiful autumn foliage.
Some cultivars can tolerate a more sunny location. On the other hand, heavy shadow produces fewer blossoms but larger leaves.
Trimming – Oakleaf hydrangeas require very little pruning, if any at all.
If pruning is required to shape or reduce the size of the shrub, do so soon after the flowers have faded.
Late in the summer, this shrub produces bloom buds for the next year.
To put it another way, it grows on ancient wood.
Pruning at any other time of year will result in the loss of the blossoms for the next year.
Insects This plant is rarely bothered by insects, with the exception of spider mites and aphids.
Deer will nibble on this plant, especially the sensitive, new spring foliage, so use a deer repellent or a physical barrier to protect it.
Propagation – Stem cuttings can be used to propagate the plant. The plant can also be propagated by layering because the branches are low to the ground.
When used as a solitary specimen, a backdrop to smaller shrubs, bulbs, or perennials, a component of a mixed border, a deciduous hedge, or a mass planting, oakleaf hydrangea is a powerful yet elegant shrub.
If oakleaf hydrangeas have a flaw, it’s that their enormous, coarsely textured foliage might be intimidating to a novice gardener. Rest confident that the foliage mixes in beautifully with plants with smaller leaves. Evergreens, for example, with their finer needles and scaly branches, provide a nice contrast. Boxwoods’ more formal round shape and compact, thick leaves contrast nicely with the looser appearance of oakleaf hydrangea. Oakleaf hydrangeas pair well with taller ferns like ostrich or cinnamon ferns, as well as shorter grass-like plants like liriope.
Easy-care The oakleaf hydrangea is particularly beneficial in the landscape because it provides year-round interest. It makes an immediate impact in the spring when its bold, beautiful leaf emerges. In the summer, the dark green foliage contrasts with the huge, long-lasting clusters of creamy white or pink blooms. Many cultivars mature to a medium pink or deep rose color over time. With its rich, deep burgundy/purple foliage that lasts all winter, the oakleaf hydrangea really shines in the fall. Additional interest is provided by the dried tan or light brown flower heads. The flaking tan bark adds a tactile aspect to the white environment in the winter.
