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.
What types of hydrangeas are smooth?
Smooth hydrangeas are easy to grow and exceptionally cold tolerant; they are native to the southern United States. This species, which is frequently misidentified as an Annabelle hydrangea, has enormous, spherical flower heads that are colored white, pink, and green.
Ideal Conditions for Smooth Hydrangeas
A position with some shade is necessary for smooth hydrangea to flourish. Plants benefit from morning light or bright shade for blossoming while being shielded from the scorching afternoon sun. Drought is a threat to plants, and they thrive under conditions of consistent wetness. a great inclusion in woodland gardens and mixed borders, or hidden beneath perennials.
Pruning Smooth Hydrangeas
On fresh wood, smooth hydrangeas blossom. In order to promote profusion of blooms and keep plants at a reasonable size, plants are frequently cut back to the ground in late winter or early spring. Cut some of the stems to the ground and leave others with varied lengths, between one and two feet, if a larger shrub is desired.
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.
How can I smooth out my hydrangeas?
Smooth hydrangeas thrive in partial shade, but they may tolerate full sun with regular watering and fertile soil.
They are water-loving plants, as their name would imply, and without enough moisture, their leaves may wilt and droop. These drought-resistant plants could need some more summer hydration.
Planting wild hydrangeas on soil that has been improved with organic material, such as compost or mulch, can help them grow the easiest in soil with medium moisture and good drainage.
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.
Can smooth hydrangeas tolerate 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.

Do hydrangeas come in two varieties?
Also known as hortensia, florist’s hydrangeas, and French hydrangeas. The most typical variety of hydrangea to be found in the US is this one. Mophead, lacecap, and mountain hydrangeas are the three different varieties of hydrangea macrophylla. As long as the winter is not too harsh and dry, some mophead hydrangeas can survive in colder climates. After a prolonged warm weather, hydrangeas are most vulnerable when exposed to a freeze. Additional protection could be needed there.
What can I grow beside smooth hydrangeas?
Shrubs including boxwood, hollies, yews, mahonia, gardenia, and loropetalum look lovely planted in front of hydrangeas. Early color will come from azalea blossoms. Since the azalea flowers will have faded before your hydrangea blooms, you can choose your preferred blossom color.
During the winter, boxwoods and evergreen azalea species will provide some color. Depending on whether you want a formal or natural-looking landscape, boxwoods can be shaped or left in their natural state. These may also offer some wintertime protection from high winds.
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.
