Are Oakleaf Hydrangeas Evergreen

Northeast Texas is a haven for oakleaf hydrangea, a native shrub of the Southeast United States.

It is great to have other plants fill in with color as the spring azalea blooms fade. Roses are a clear choice because many of them are already in bloom, and the main show will begin in a few weeks.

The Oakleaf hydrangea in our yard is one of my favorite plants. With its huge leaves, lovely white blossoms, intriguing bark, and unique growth habit, it offers appeal almost all year round. It blooms in early to mid-May and creates a fascinating contrast in form and color with our native Rhododendron oblongifolium (Texas azalea), which flowers white, and a late-blooming pink Wakaebisu azalea.

East Texas benefits greatly from the oakleaf hydrangea (Hydrangea quercifolia) as a shrub. This medium-sized, deciduous shrub, which is native to the Southeast of the United States and grows to a height of 6 to 8 feet, possesses a number of qualities that make it a standout. In east Texas, finding a partially shaded spot is typically not too difficult. Sunlight in the morning or evening is best. It will flourish in areas with more sunlight and soil that is consistently moist. In regions with more sunlight, newly planted specimens have a tendency to wilt throughout the day the first year.

Oakleaf hydrangeas produce enormous, alluring, beautiful, conical inflorescences of creamy white flowers in late May and early June. The magnificent white flowers, which are supported above and distinguished by the big leaves, are produced by all of the identified cultivars. Flower clusters can be between 3 and 4 broad and 4 to 12 long. The flower clusters eventually become pinkish and continue into the fall and winter as a brown papery cone.

The enormous (up to 8 inches), oak-shaped leaves—which are gorgeous all summer long—continue the show in the fall and become a deep purple or burgundy before falling off in the winter to reveal lovely exfoliating bark up and down the erect branches. Plants growing in more sunny environments will have more noticeable leaf color. On stems older than three years, the outer bark starts to peel away to reveal a rich, dark brown inner bark.

Use oakleaf hydrangeas as an accent plant, in a naturalized shrub border, in front of tall evergreens, on the edge of a forested lot, or close to water, or anywhere a striking texture is required.

The oakleaf hydrangea is hardy, tolerating a wide range of soil and moisture conditions, long-living, and widely accessible. It also has a very low insect population. Recall to give it room to expand.

Most people immediately see the “French or Bigleaf hydrangea” when you mention hydrangeas (Hydrangea macrophylla). Although this dazzling shrub was extensively hybridized by the French around a century ago, it is not native to France. A native of Asia, bigleaf hydrangeas today fall into two categories: hortensias and lacecaps. The hortensia genus produces enormous balls or clusters of pink or blue flowers, and is the one that is most usually seen around homes. The non-showy fertile flowers in the center of the lacecaps are surrounded by showy fertile blooms, giving the plant a delicate, lacy appearance.

Numerous novel cultivars are entering the market and there are countless others that rebloom on new growth for a longer duration of color.

Its botanical name, “Hydra,” which means water in Latin, serves as a hint that these large-leaved plants require a lot of water during the summer to prevent wilting of the leaves and blossoms.

The optimal conditions for hydrangeas are a mild shade exposure, rich, well-drained loamy soil, and a thick mulch 4 inches deep to keep the soil moist. Because the color of the blossoms can tell you whether your soil is acidic or alkaline, hydrangeas are like living litmus paper. While less acidic soils (pH 6.06.5) turn the flowers pink, strongly acidic soil (pH 5.05.5) produces blue blossoms. The majority of the soils in east Texas are acidic, so if you want pink blooms the following summer, add lime to the soil in the fall. Acidifying the soil with aluminum sulfate, sulfur, or ferrous sulfate will encourage bluer flowers. The true factor influencing the flowers’ blueness is the soil’s accessible aluminum level, which is tied to the soil’s acidity.

Due to variable pH levels in the soil surrounding the plant, it is occasionally possible for a single plant to have pink and blue hues at the same time. Two well-liked cultivars with reliable blue flowers are “Nikko Blue” and “Merritt’s Blue.”

Bigleaf hydrangeas can be blended with other evergreen and deciduous plants as an accent plant and in shrub borders. They look best when pruned on a regular basis. Flower buds grow in the late summer and fall, so be sure to prune as soon as they stop flowering. Stems that have blossomed should be cut off, while stems that haven’t should be left. While the stems may appear to be dead throughout the winter, they actually hold the leaf and flower buds for the next spring. A harsh winter may ruin the flowers for the next year.

Are oakleaf hydrangeas leafless in the winter?

In reference to their love of water and the design of their seed pods, hydrangeas are shrubs whose name is a combination of the Greek words for vessel and water (hydor). Since hydrangeas are vigorous, shade-loving shrubs with huge, dramatic blooms that are often much better suitable for locations with humid air and summer showers, Master Gardeners in Sonoma County rarely recommend them as good garden choices. The oakleaf hydrangea, Hydrangea quercifolia, is a notable exception, though. It not only survives in our climate, unlike the mophead and lacecap species, but also makes a beautiful garden specimen. The only hydrangea on our list of suggested plants for Sonoma County is this one.

Native to the Southeast of the United States, H. quercifolia got its name from the way its leaves were highly lobed, resembling those of a northern red oak (Quercus rubra). Other hydrangeas’ leaves are not lobed, but that’s not the only distinction. The leaves of H. quercifolia are also thick, coarse, sparsely serrated, and bristling with minute hairs on the undersides. It is the only hydrangea that can cohabit peacefully in our gardens with low-water Mediterranean and native plants from California thanks to its thickness and pubescence (hairiness).

When fully grown, oakleaf hydrangeas often reach heights of 6-7 feet and widths of 7-8 feet, with a beautiful mounding habit as opposed to the spherical, more formal shape of its relatives in the genus. They may thrive in a variety of exposures, from full sun to full shade; dappled shade is optimal. They also require less water than other members of the species. Plants need more shade in the interior; the closer they are to the coast, the more light they can withstand.

In comparison to other hydrangeas, H. quercifolia grows quite slowly and has no known disease or pest issues. As a result, it is a good garden neighbor who doesn’t require a lot of attention or water. All hydrangea portions are mildly poisonous if consumed, just like other hydrangeas.

Oakleaf hydrangeas are cultivated largely for their white, conical summer flowers, which can measure almost a foot in length. Oakleaf hydrangea foliage puts on a fall coat of gorgeous, spectacular color, ranging from crimson to purple to bronze, as many summer-flowering shrubs wither and drop their leaves.

Although it is technically a deciduous tree, it keeps its leaves well into the winter. The shrub becomes barren as they fall, exposing its rusted, flaking branches and stems. An interesting winter feature on older stems is the shredded, cinnamon-colored bark, which is reminiscent of manzanita and arbutus. New growth appears in the spring and has an eye-catching color and texture along with silky, soft hairs.

H. quercifolia can be cultivated singly, in modest clusters, or as a border for a landscape. It’s also used in bulk plantings in some expansive gardens. There are designated variations that are supposed to generate larger plants and enhance blossom size and shape; some grow to a height of 15 feet; these types should be carefully chosen. Although the flowers are a little heavy, “Snowflake” is a popular selection. Pee Wee and “Sikes Dwarf” are suggested for smaller gardens because they grow to a height of 4-6 feet. Munchkin’s height and width remain at 3 feet.

Exists an evergreen variety of hydrangea?

No one! Because of this, a garden isn’t finished unless it has at least one hydrangea. These flowering shrubs are a constant delight with their lovely leaves and enchanted blossoms. Additionally, as long as you choose the appropriate variety for your environment, hydrangeas are simple to maintain.

In order to choose the hydrangea to cultivate, consider the following. On choose the best hydrangea variety for your yard, consult our guide to hydrangea varieties.

Hybridizing hydrangeas is simple! Find a hydrangea variety that will flourish in your garden by simply responding to these inquiries.

How much sunlight do hydrangeas require? The majority of hydrangea varieties prefer a morning blast of full light followed by an afternoon nap in the shade. Be cautious to verify though, as some hydrangeas do well in direct sunlight.

What shade of hydrangea would you like? Although hydrangea color may appear significant, it is not! Pink hydrangeas can be made from blue ones, and vice versa. Acidity of the soil affects the saturation and color of hydrangeas. The sole distinction? Hydrangeas that are white remain that hue.

3. What hydrangea size do you want? There are tiny, medium, and giant hydrangea varieties. Dwarf hydrangeas are only 3-5′ tall and wide, but larger kinds can reach heights of 20′ and widths of 18′. You may choose a hydrangea that works in any garden size, even container gardens.

4. Which hydrangea variety should I grow? Your hydrangea has to be clipped at various periods depending on the kind that you are growing. To make future trimming simple, make a note of the type of hydrangea you have. Bigleaf, oakleaf, panicle, and smooth hydrangeas are a few of the most popular varieties.

5. Is the hydrangea deciduous or evergreen? Hydrangeas with the moniker “evergreen” remain green all year long. Since the majority of hydrangeas are deciduous shrubs, they lose their leaves every year.

What color are oak leaf hydrangeas throughout the winter?

When you say the word “hydrangea,” most people immediately picture the Hydrangea macrophylla mophead and lacecap varieties. These magnificent bushes are highly well-liked and frequently blossom in summer landscapes across the nation. The oakleaf species of hydrangea (H. quercifolia), a less popular variety with a distinctive appearance and texture, is a hydrangea. Oakleaf hydrangeas also produce enormous, spectacular flower clusters, much like the mopheads and lacecaps. However, that is about where the similarities between the oakleaf hydrangea and its relatives end.

The oakleaf hydrangea differs from the other members of the genus in a number of important ways.

• Flowering behaviorOakleaf hydrangeas produce inflorescences, or long, cone-shaped clusters of flowers (flower heads consisting of a group or cluster of flowers arranged on a stem). The inflorescences are made up of both conspicuously fertile and ostentatious infertile blooms. The mophead hydrangeas, on the other hand, feature globe-shaped clusters of sizable florets. The flattened bloom heads of lacecap hydrangeas are flanked by larger male flowers and smaller female flowers.
• Foliage

Oakleaf hydrangea foliage is big (4 to 12 long and wide, depending on the selection), lobed, and coarsely textured, in contrast to the leaves of H. macrophylla species, which tends to be moderately sized, oval or heart shaped, and smooth textured. The botanical name of this shrub, quercus folium, is derived from the Latin words quercus (oak) and folium, which describe the foliage as having a form resembling that of an oak leaf (leaf).

• Origin The 23 identified species of hydrangea that make up the genus are primarily Asian in origin. The smooth hydrangea (H. arborescens) and oakleaf hydrangea are the only two exceptions that are indigenous to this nation. All of the states in the southeastern region of the United States, from North Carolina south to Florida and west to Louisiana, are home to the native oakleaf hydrangea.
• Fall hues

The only plant in the genus that has any discernible fall leaves colors is the oakleaf hydrangea. The oakleaf hydrangea is still fully covered with gorgeous deep crimson to purple leaves in November and December, when the majority of other deciduous plants have lost their foliage. These leaves last well into the winter.

• cultural prerequisites In general, all hydrangeas prefer moist, well-drained soil. The oakleaf species can endure drier soil and more sun than other species in the genus, albeit, once established.

A rounded, deciduous shrub with a mounding form from the ground up is an oakleaf hydrangea. Large clusters of blooms are supported by strong, sturdy stems above typically dark green on top and yellowish green underneath foliage. The stems have appealing tan or cinnamon colored bark that falls off in small pieces. This understory shrub is typically found growing in the wild beside streams, on forested hillsides, and in the shade of mixed hardwood trees. It is an ornamental plant that thrives in a natural or groomed woodland setting that is somewhat shaded, particularly with morning sun and afternoon shade. Some varieties are hardy to zone 5, and it is hardy from zones 6 through 9.

On the wood from the previous year, magnificent clusters of creamy white or pink flowers bloom, depending on the cultivar. While just a few varieties produce double flowers, the majority of them do. The flowers are produced in inflorescences that are 6 to 12 inches long and 3 to 5 inches broad, and they last for at least four to six weeks before turning tan or deep pink. Through the autumn, the blossoms provide interest to the plant by drying in situ.

The list that follows, while not exhaustive, describes a variety of oakleaf hydrangea choices, as well as their typical sizes and floral arrangements. While a few varieties can reach heights of 12 feet or more, the majority of cultivars are medium-sized, with an average height of 5 to 8 feet. There are several compact cultivars that grow to a height of 4 feet or less and with proportionately smaller leaf and flower clusters available for gardeners with tiny gardens.

• 12′ tall by 12′ wide is “Alice.” This is a wise choice for bigger gardens that have the space for a shrub of this size. The enormous white blossoms eventually turn tan in the late summer after maturing to rosy pink. The State Botanical Garden of Georgia’s gold medal award for 2000 went to “Alice.”
• Alison is 8 to 10 feet tall. Despite being comparable to “Alice,” this cultivar is a touch wider and has inflorescences that are held more upright. By the end of the summer, the huge white bloom clusters have turned pink and are now tan.
• Harmony is 10′ broad and tall. This variety has clusters of enormous, many, double, sterile blooms. Branches can bow under their weight. This cultivar, which is extraordinarily lovely but not frequently seen in nurseries, may be a challenge due to the flowers’ weight.
• 6′ tall by 6′ wide is “Amethyst.” Dr. Dirr created a small cultivar whose blossoms change from white to rose. As they become older, “Alice” and “Amethyst” both develop extremely deep pink inflorescences.
• 5 to 6′ tall by 5 to 6′ wide is the “Gatsby Gal.” This, along with the next two choices, are from Proven Winners’ 2016 release of the Gatsby series. Flowers on the shrub ‘Gatsby Gal’ are upright, giving the impression that they are larger than the shrub’s relatively small size.
• Gatsby Moon is 6 to 8 feet tall and 6 to 8 feet wide. The inflorescences are composed of closely spaced, extremely full double flowers similar to those on “Harmony,” as previously mentioned. Instead of turning pink with age, the petals become white to green.
• Gatsby Pink is 6 to 8 feet tall and 6 to 8 feet wide. The enormous, protracted flower heads quickly transition from white to a deep shade of pastel pink.
• Queen of Hearts measures 6.5″ high by 9″ broad. This cultivar was created by the shrub breeding program of the U.S. National Arboretum through the hybridization of the cultivars “Snow Queen” and “Pee Wee,” the same cross that also gave rise to the cultivar “Ruby Slippers” that is detailed below. The blossoms start out white and gradually turn a rich pink hue.
• 6′ tall by 6′ wide is the “Snow Queen.” ‘Snow Queen’ can withstand brighter conditions and retains its single-flowered inflorescences more upright than other varieties. The 2012 Royal Horticultural Society Award of Garden Merit was given to it.
• 7′ tall by 7′ broad is “Snowflake.” This cultivar, like the others that won the Royal Horticultural Society’s Award of Garden Merit in 2012, has a longer bloom season. It has double hose-in-hose flowers on very long (15 inch) spikes that stay on the plant for a very long time. The blossoms progressively turn pink as they deteriorate, then light tan.
• Little Honey measures 4′ high by 5′ broad. The golden yellow spring foliage, a sport of “Pee Wee,” gradually darkens to chartreuse green in June and then becomes red in the fall. For optimal results, give it morning sun and afternoon shade. Compared to other oakleaf hydrangea species, the white blooms’ 5 to 6-inch long, cone-shaped inflorescences are diminutive.
• ‘Munchkin’

4.5′ broad by 3′ high. The shrub breeding program at the U.S. National Arboretum in McMinnville, Tennessee, created Munchkin. It is the perfect option for modest home landscapes because of its compact form and dense plant habit. The flowers start out white and progressively change to a medium pink color.

• Pee Wee is usually 5 feet tall and 4 feet wide, but they can get bigger. Until quite late in the growing season, this upright, compact variety retains its deep burgundy and purple leaves before losing them. The leaves typically have 3 to 7 lobes and are on average 5 inches long. In the late summer, the flowers become tan.
• “Ruby Slippers” are 3.5″ high and 5″ broad. This mounding, semi-dwarf cultivar was created by the shrub breeding program of the U.S. National Arboretum through the crossbreeding of the cultivars “Snow Queen” and “Pee Wee.” The flowers begin as white but quickly change to a delicate pink hue, which later in the summer intensifies to rosy red.
• Sikes Dwarf is 2 to 4 feet tall and 3 to 4 feet wide. This compact collection works well in container gardens as well as smaller areas. The sterile florets in the flower clusters, which gradually turn light pink as they ripen, conceal the fertile blooms. ‘Sikes Dwarf’ has an asymmetrical spherical shape and an open plant habit.

The soil that Oakleaf hydrangea prefers has a pH of 5.06.5 and should be organic, fertile, well-drained, and slightly acidic. Once planted, it is drought hardy, though it does need water in extremely dry conditions. Effective drainage is crucial. Although the plant prefers moist soil, wet feet are intolerable.

Sunlight

In either complete or partial shade, this shrub can flourish. But it functions better when it receives at least a half-worth day’s of sunlight or more, which results in a better floral show, stronger stems, and more vibrant autumn foliage. Some varieties can tolerate a sunnier location. On the other hand, plants under heavy shadow will produce fewer blossoms but bigger leaves.

In general, Oakleaf Hydrangea trimming is little to nonexistent. Pruning should be done soon after the shrub flowers if it needs to be shaped or shrunk. In late summer, this shrub produces bloom buds for the following year. Or put another way, it grows on aged wood. Any other time of the year will result in the loss of the flowers for the following year when pruned.

Pests The only insects that occasionally harm this plant are spider mites and aphids. Deer will nonetheless munch on this plant, especially the sensitive, young spring foliage, so either use deer repellent or put up a physical barrier to protect it.

Propagation

Cuttings of the shrub’s stems can be used to multiply it. Layering is another method of plant propagation that can be used because the branches are low to the earth.

When used as a solitary specimen, a backdrop for smaller shrubs, bulbs, or perennials, a part of a mixed border, a deciduous hedge, or as part of a mass planting, oakleaf hydrangea is a multipurpose shrub that is bold yet graceful.

If there is a drawback to oakleaf hydrangeas, it is that a cautious gardener can find their enormous, rough-textured foliage intimidating. Rest certain that the foliage complements plants with smaller leaves extremely well. For instance, the contrast created by evergreens’ finer needles or scaly branches is appealing. Boxwoods’ smaller, more compact leaves and more formal round shape contrast nicely with the more relaxed shape of oakleaf hydrangeas. Oakleaf hydrangeas go nicely with taller ferns like ostrich or cinnamon ferns as well as shorter grass-like plants like liriope.

Easy-care Oakleaf hydrangea is particularly useful in the landscape since it provides year-round appeal. It has an immediate effect in the spring when its striking foliage first appears. Large, persistent clusters of creamy white or pink blooms stand out against the dark green leaves in the summer. Many cultivars develop to a medium pink or deep rose color over time. The oakleaf hydrangea especially shines in the fall with its deep, burgundy/purple foliage that lasts all the way through the winter. The pale brown or brownish dried flower heads provide more appeal. The tan bark’s exfoliation adds a new tactile dimension to the snowy scene in winter.
