Smooth hydrangeas are attractive-looking shrubs with enormous white blooms, sometimes known as wild hydrangeas. The bushes are endemic to the Southeast of the United States and, like all other hydrangeas, are deciduous (meaning they lose leaves in the winter). USDA growth zones 3 to 9 are suitable for cultivating these shrubs.
The main draw of this variety of hydrangea is its enormous, creamy white blossoms. The shrub is pale green when it first blooms. The flower becomes a creamy/bright white as it ages. Pink blooms are produced by a few of the more recent cultivars (such Invincibelle Spirit). These blossoms eventually wilt and turn brown. These flowers cannot be dyed a different hue, unlike mophead (macrophylla) hydrangeas.
Spread hydrangeas that are smooth?
Smooth hydrangeas are effective at preventing erosion because they spread widely and sucker readily. Shrubs should be spaced at least five feet apart.
What size can a smooth hydrangea reach?
Hydrangea arborescens (Smooth Hydrangea), a profusely branching deciduous shrub native to the Eastern United States, is prized for its creamy-white flower clusters that enliven the landscape and brighten dark places. The distinctly domed to nearly spherical blooms, which bloom freely from early summer to fall, start out lime-green, turn beautiful creamy-white, and then turn tan in the fall. This superb flowering shrub has large, egg-shaped, highly serrated leaves that are dark green in the summer and turn butter-yellow in the fall, extending the interest season.
- Smooth hydrangeas typically reach heights and widths of 3-6 feet (90-180 cm).
- Smooth Hydrangeas are cold-tolerant and can withstand harsh winters and extreme cold. In cooler climates, they make wonderful alternatives to Mophead Hydrangeas (Hydrangea macrophylla).
- Smooth hydrangeas are surprisingly drought resilient and can be grown in full sun or partial shade (the more shade required, the hotter the area). Average, medium, well-drained soils are ideal for growing plants. If there is constant moisture present, full sun is tolerated.
- Perfect as a flowering hedge, for the shrub or mixed border, or as a backdrop for your favorite perennials.
- Smooth hydrangeas need to be pruned in late winter or early spring to promote brisk development because they bloom on new wood. The flowerheads will get bigger the more you prune, even to the ground.
What distinguishes hydrangeas with panicles from those with smooth petals?
First and foremost, you need to be aware that not all hydrangeas are hardy. I’m referring specifically to the mophead hydrangeas (hydrangea macrophylla). The gorgeous blue and pink hydrangeas that can be found all across the Lower Mainland are called mophead hydrangeas.
Hydrangeas of the smooth and panicle types (hydrangea paniculata) overwinter successfully here (hydrangea arborescens).
Flowers Cone-shaped flowers are supposedly characteristic of panicle hydrangeas, but I only sort of agree with that description. According to me, depending on the variety, the cone shape might be either quite clear or highly ambiguous. The size of the flower also varies widely.
The flowers of smooth hydrangeas are larger and dome-shaped. The flower size is more constant (between 6 and 12) “amongst variations (measured in diameter).
Hardy hydrangeas come in countless colors of white, pink, and lime when it comes to flower color. The tones and/or colors of the blooms frequently change as they become older.
Smooth hydrangeas have green, flexible, generally softer stems than panicle hydrangeas, which have reddish, woody, robust stems. This is because smooth hydrangeas sprout from the ground every year, but panicle hydrangeas regenerate on growth from the previous season.
The leaves of smooth hydrangeas are lighter green and softer, whereas those of panicle hydrangeas are often darker green and more leathery.
The need for trimming differs significantly between panicle and smooth hydrangeas.
The branch tips of panicle hydrangeas only need a minimal annual trimming. (If your ancient panicle hydrangea is no longer flowering nicely, that is the exception.) The hydrangea will then require “inspiration” to bloom once more. In the early spring, simply prune a couple of the oldest stems as close to the ground as you can.)
Every year in the early spring, smooth hydrangeas require severe pruning. Reduce all stems to around 3-6 inches “from the ground. Because of this, if your intended planting site is prone to significant winter snow loads, smooth hydrangeas are a preferable option.
Depending on the type, a mature hardy hydrangea can range in size from 3′ × 3′ to 10′ x 10′.
Hydrangeas can be planted in the following ways, as shown in the photo gallery below:
- shrub used as a focal point or in combination with other perennials and shrubs
- as a planting of a foundation (meaning against the foundation of a house)
- as a planting campaign
- like a hedge
- like a tiny tree (see note below)
Note: Hydrangea trees are actually hydrangea plants that have been fashioned to seem like trees. Selective pruning for several years is required for this process. Any hydrangea can be trained into a tree if you have the patience to do so (otherwise, ready-made tree hydrangeas are available.)
Although hydrangeas are simple to grow, they do require wet soil. Hydrangeas will express their dislike of being dry. Your hydrangea should flourish if the soil is adequately prepared, mulch is added around the base of the bush, and thorough, infrequent watering is practiced.
Shade tolerance varies among different hydrangea cultivars. In general, hydrangeas can thrive in locations with at least three hours of sunlight per day.
Because hydrangeas flower a lot, fertilizing them is a smart option. Use just fertilizer for transplants and bone meal during the first year. To maximum bloom production after that, apply a slow-release fertilizer once a year.
I haven’t met a hydrangea that I didn’t enjoy, but the following is a good representation of the kinds that are out there:
You’ll agree that this hydrangea’s name is fitting once you see it in bloom. Bombshell is covered in so many flowers when it is in bloom that its leaves are hardly visible. Indeed, compared to other panicle hydrangeas, it produces the most flowers.
White blossoms gradually turn to delicate pink as they ripen. Bombshell has a longer flowering time and begins blooming earlier than the majority of panicle hydrangeas.
Bombshell is a compact and well-kept tiny hydrangea that matures to a height and width of about 3′.
The reason Invincibelle Spirit made the list is because it is the first (and only) smooth hydrangea with pink flowers. The huge, dom-shaped blossoms appear in the middle to end of the summer.
A medium-sized hydrangea, Invincibelle Spirit eventually grows to be 3–4′ high and broad.
The new and better version of “Annabelle” is called “Incrediball.” (Annabelle was found in 1910 in Anna, Illinois.) Despite being beautiful, Annabelle’s flowers frequently flop, giving the plant a disorganized appearance. If an Annabelle is hit by a lot of rain, it will appear more like a tornado landed on it.
Incrediball, on the other hand, has exceptionally strong stems that maintain the flowers upright. The really shocking part is that Incrediball’s flowers are much larger, with a maximum diameter of 12″! When fully opened, the blossoms turn white before turning back to lime green.
Little Lime is the hydrangea I’m currently obsessed with. Last season, they were on show in a stunning way at our front entry, and I couldn’t take my eyes off of them. I approached numerous times to take in the sight of their captivating, beautifully colored petals.
White, lime, pink, and other colors are all present in the thick flower clusters of the Little Lime plant. In terms of blossoming, it is very productive.
Because Quick Fire blooms one month earlier than the other hardy hydrangea varieties, it is a prized variety.
Quick Fire is shaped like a free, airy flower. The blossoms start out white, then turn pink, and then intensify into cherry red.
We only started growing Fire Light in 2014. However, it merits note due to the distinctive flower’s color and shape.
Fire Light flowers start out white and turn a rich pink color as they age, just like most pink hydrangeas. The panicles of the flowers have a very distinctive, dramatic shape.
Hardy hydrangeas are one of our region’s best flowering shrubs. Give any hardy hydrangea type you come across that I haven’t listed a try. You might really like it.
To explore many more hydrangeas, including those that will be available in 2016, visit the Proven Winners website. I’m eager to give them all a try!
Do smooth hydrangeas enjoy direct sunlight?
The majority of hydrangeas only like morning sun. The panicle hydrangea is the only variety of hydrangea that can remain in the sun all day. Although they can tolerate the sun, these also thrive in some shade. Additionally, panicle hydrangeas are the most resilient varieties.

Smooth hydrangeas bloom for how long?
Smooth hydrangeas are a more common name for wild hydrangea plants (Hydrangea arborescens). They are deciduous plants that are native to the Southeast of the United States, but they may be grown in USDA plant hardiness zones 3 through 9. From June until the start of the first frosts, the wild hydrangea plant blooms.

Which species of hydrangea blooms on fresh wood?
Panicle hydrangeas, also referred to as PeeGee, are strong plants with exceptional hardiness and drought tolerance. They can survive the sweltering summers in the deep South and the bitter winters in the north. Despite their enormous blooms, these hydrangeas are among the easiest to grow. Show-stoppers like Moon DanceTM and White Wedding Hydrangea compete favorably with bigleaf types.
Ideal Conditions for Panicle Hydrangeas
Panicle hydrangeas can withstand a variety of soil types and are hardy to zone 4. In full sun to partial shade, plants thrive, and sun promotes the best flowering. To help plants take root, water them well in the first season. Perfect for containers as well as massing and hedging.
Pruning Panicle Hydrangeas
Panicle hydrangeas can be cut in the winter or early spring before new growth appears because they bloom on new wood. Although pruning is not required, it can encourage more flowering. Panicle hydrangeas can withstand severe trimming to keep their size and are occasionally made into trees.
Which hydrangeas thrive in direct sunlight?
While many hydrangea species do well in the shadow, panicle hydrangeas (Hydrangea paniculata) do best when grown in full sunlight. Large clusters of white blooms are produced by these summer-blooming bushes for several weeks. The colorful blossoms dry to a beige color after fading to pink or crimson hues. The blossoms on the plant typically dry in the fall and retain their aesthetic quality for the whole of the winter. One of the toughest species, Hydrangea paniculata, thrives in Zones 4 to 8.
Outstanding Panicle Hydrangea Varieties
- The name “Grandiflora” is also used for peegee hydrangeas. It can grow to be a 20-foot-tall miniature hydrangea tree or a huge shrub.
- From summertime to late fall, ‘Limelight’ blooms with pale lime green flowers. It grows to be eight feet tall.
- Large clusters of white flowers on Vanilla Strawberry (Hydrangea paniculata ‘Rehny’) fade to strawberry pink as the season progresses. About seven feet is how tall it gets.
Are smooth hydrangeas pruned?
A: Different types of hydrangeas require different amounts of pruning, so it’s important to know which kind you have before you start. Always cut back any winter-damaged branches in the early spring in addition to the methods described below.
- The climbing hydrangea (Hydrangea anomala ssp. petiolaris) can reach heights of 50 to 60 feet and simply needs to be pruned to stay contained. Trim the trees in March.
- Early in March, the smooth hydrangea (Hydrangea arborescens), which blooms on new wood, needs to be severely clipped to a height of 1 foot. This plant spreads by putting up a lot of low-lying suckers, which can easily be removed. Regular pruning prevents a top-heavy shrub from flopping to the ground in the middle of the season.
- The bigleaf hydrangea (Hydrangea macrophylla), which blooms on old wood, needs to be clipped right away. Gardeners should avoid waiting until too late in the season to prune because doing so can encourage sensitive new growth that might die during the winter.
- The smooth hydrangea (Hydrangea paniculata) and its cultivars require harsh pruning, whereas the panicle hydrangea (Hydrangea paniculata) and its cultivars do not. If one-third of the old growth is cut back in late winter, they will look their best. These varieties can grow to a height of 20 feet if left unpruned, which might be excessive for some landscapes.
- Although the oakleaf hydrangea (Hydrangea quercifolia) also blooms on old wood, it is frequently left unpruned due to its lovely spreading habit. The enormous, 12-inch blossoms are highly attractive and will give the fall garden some late-season appeal. The plant won’t flower if the terminal buds of this type are killed off over the winter.
