What are hydrangeas with mopheads? These hydrangea shrubs are deciduous and boast huge flower heads. They are popular among gardeners because they are showy, simple to care for, and consistently bloom each summer. It won’t surprise you that mopheads also go by the name bigleaf hydrangeas once you see how big the leaves can get—sometimes as huge as a dinner plate. They give the shrubs a rich, rounded appearance and are a vibrant, fresh green.
According to information about mophead hydrangeas, the shrubs can get as tall as you are and spread out equally as much as you do. If properly spaced, they may grow pretty quickly and create great hedges. There are two varieties of mophead hydrangeas. Some mopheads have huge, spherical clusters of tiny blooms that can resemble cabbages in size. Lacecaps are the other variety of mopheads. These bushes produce flower clusters that resemble flat disks with spectacular, bigger bloom edges.
If you grow mophead hydrangeas, you are probably familiar with the “magic trick” of the plant. These hydrangeas have a spectrum of hues. An acidic soil is necessary for a mophead to grow blue flowers. The blossoms will grow in pink if you cultivate the same bush in alkaline soil.
What hydrangeas have mophead flowers?
The most common hydrangea variety grown in landscapes and backyard gardens is mops (Hydrangea macrophylla). While a few types of mopheads are developed today in white, the majority are blue or pink. These are additionally frequently called French hydrangeas.
Both Mophead and Lacecap Hydrangeas fall under the Hydrangea macrophylla genus. The growing environment is the same for both types.
Depending on the soil’s makeup, any mophead hydrangea (apart from the white ones) may be blue, purple, or pink.
What kind of hydrangea has a mop head?
Mopheads. Mophead hydrangeas produce enormous, dome-shaped clusters of blue, pink, or white blooms. Late spring or early summer is when the majority of mopheads blossom. Their flower heads frequently remain attractive into the winter because they naturally dry on the plant.
What distinguishes lacecap from mophead hydrangea?
Bigleaf hydrangeas, also known as Hydrangea macrophylla, are the most popular variety of hydrangea. French hydrangea, garden hydrangea, and florist’s hydrangea are some more frequent names for this plant. Most likely, the hydrangeas at your neighborhood florist are bigleaf varieties.
Bigleaf hydrangeas come in three different varieties:
- Due to their huge, puffy bloom heads, mophead hydrangeas are the most recognizable and well-liked hydrangeas. They flourish in hardiness zone 6, and their blossoms can be purple, blue, or pink. Mophead hydrangea flower buds may not endure the winter since they are susceptible to the cold.
- With their flowers being the main distinction, lacecap and mophead hydrangeas are nearly identical to one another. They have little, fruitful flower buds in the middle, and the showy flowers surround the flower head’s margin. The main function of these gorgeous, sterile flowers is to entice bees and butterflies to the fertile buds in the middle. They flourish in hardiness zone 6, just like mophead hydrangeas do.
- The least frequent variety of bigleaf hydrangeas are mountain hydrangeas. Its scientific name is Hydrangea serrata, and while its flattened heads resemble those of lacecap hydrangeas, its flowers and leaves are much smaller. Mountain hydrangeas are a fantastic alternative for locations with late winter cold snaps because they have hardier buds and do well in hardiness zone 5.
True to its name, the bigleaf hydrangea’s trait that sets it apart from other hydrangea varieties is the size of its leaves. The leaves of bigleaf hydrangeas can get up to 4-6 long and 3-5 broad. The leaves have short stalks, are heart-shaped, thick, and lustrous.
Bigleaf hydrangeas like some shade, but not too much, as this can lead to fewer flowers. They prefer moist, well-drained soil, and their blooming seasons are in June and July. Given that bigleaf hydrangeas are drought-sensitive, it is crucial to consistently water them.
By adjusting the soil’s acidity, you can vary the color of your hydrangeas. Blue flowers can be grown on acidic soil with a pH of 5.5 or below. Pink flowers will grow on neutral or alkali soils with a pH of 6.5 or higher. Purple flowers or a hybrid of blue and pink flowers will grow in soil with a pH between 5.5 and 6.5.
How are mophead hydrangeas cared for?
Mophead hydrangeas are easy to grow and don’t require much skill. As long as they are planted in the right locations, these shrubs thrive with little upkeep. If you plant mophead hydrangeas in USDA plant hardiness zones 5 through 9, caring for them will be the simplest. They thrive in full sun in temperate climates, but in areas with hotter summers, choose a location with afternoon shade.
There are only a few key elements to keep in mind if you’re looking for advice on how to grow a mophead hydrangea.
Include routine irrigation with your shrub installation. Their water requirements decrease as their root systems mature. Typically, you only need to water during extended dry spells of more than a week. However, you might need to water more frequently if you’re growing mophead hydrangea in direct sunlight. You can use less water when irrigating once the summer heat has passed.
Pruning is not always necessary for mophead hydrangea maintenance. If you do want to prune your hydrangea, do it immediately following the shrub’s flowering season.
Do you prune hydrangeas with mopheads?
First and first, it’s crucial to understand that mophead hydrangeas never need to be cut back, unless they are quite old. The only pruning necessary for the plant’s health is the removal of dead stems, which can be done whenever you like. Additionally, dead blooms can always be removed.
However, if your hydrangea is getting much too big (or old) and has to be pruned, utilize one of the techniques listed below.
If you have mophead or lacecap hydrangeas (the only varieties that are often blue or pink) or oakleaf hydrangeas, use Method One (leaves shaped like large oak leaves, white blooms).
If you have paniculatas (PeeGees) or “Annabelle,” use Method Two (arborescens). PeeGee and smooth hydrangeas have white blooms.

Mophead hydrangeas bloom for how long?
One of the most well-liked hydrangeas in our gardens is Hydrangea macrophylla (Big Leaf Hydrangea), which is native to Japan. This deciduous shrub has a rounded form, big, strong leaves, and lovely clusters of June flowers that bloom for a long time. The Mophead Hydrangeas and the Lacecap Hydrangeas are the two subspecies that make up the species.
- Large, spherical flower heads covered largely in showy, sterile florets are produced by Mophead Hydrangeas or Hortensias. The blooms will continue to bloom nonstop throughout the summer, for a period of three to six months, until October arrives and they begin to change color. Rich blues that turn wine-red can be quite spectacular, as can whites that turn pale green or even blood-red.
- The flattened flower clusters that Lacecap Hydrangeas create are made up of showy, sterile florets that radiate out from a core cluster of tiny, fertile florets. The lacecap blooms will fade much more quickly than the mopheads since the fertile florets will be pollinated, only holding their beauty for around a month.
- Deep blues, vivid pinks, pure whites, lavender, and intense red and purple hues are just a few of the many colors available. The majority of Hydrangea macrophylla varieties have the additional allure of changing color according to the pH of the soil. These species can grow blue blooms in highly acidic soils, whereas pink flowers can grow in somewhat acidic soils. If you want your Hydrangea’s blossoms to be a different hue, you can amend the soil with aluminum sulfate to make them bluer or with lime to make them pinker.
- Zones 6 through 9 are hardy, Bigleaf Hydrangeas prefer a thick layer of mulch all year round because they are more susceptible to cold than their relatives (shredded bark, peat or compost ). This will control weed growth, hold onto moisture, and lessen soil temperature swings.
- Bigleaf Hydrangeas prefer sun to partial shade and do best in rich, medium-moisture soils that drain well. They can only survive full sun if the soil is continually moist.
- No significant pest or disease problems. Keep an eye out for leaf spots, mildew, bacterial wilt, and bud blight.
- Perfect for container and foundation plantings. grouped in a protected area or used as a decorative plant. They work well as a hedge and also make wonderful cut flowers! Perfect for gardens near the sea because of their hard, glossy leaves, which can tolerate wind and salt.
- After flowering, Bigleaf Hydrangea stems should be trimmed by being cut down to two sound buds. In the early spring, remove weak or winter-damaged stems.
Mophead hydrangeas bloom in what month?
climatic difficulties When it comes to their mophead hydrangeas not flowering, gardeners have been frustrated during the past few winters. Healthy plants must meet seven requirements, with #4 and #7 being the most frequent causes of failure.
Any plant needs to be healthy in order to bloom. This indicates that the plant is receiving enough light, nutrients, and water to produce blossom buds when the time is right. Unfortunately, improper trimming and inadequate winter protection can swiftly undo all of the progress you and the plant have made.
Everblooming mophead hydrangeas have a special quality that distinguishes them from other plants: they may bloom on both fresh and old wood. In other words, flower buds form in April or May to open in July, August, or September, and flower buds form in August to open in May or June the following year. The plant is undergoing a lot of activity, which requires a lot of nourishment. Remember that any kind of stress can prevent this from happening.
The 7 steps to success with Mophead Hydrangeas:
1 – Proper Placement Mophead hydrangeas wilt quickly in the heat of July. The homeowner waters the plant regardless of whether it requires it because of that wilting. To provide protection from the intense sun, this species of hydrangea should be planted on the north or east side of a building. Regarding proper irrigation, see #6. Mopheads don’t need a lot of light to bloom, but they won’t set buds if the environment is too dark.
2. Soil modifications at the time of planting
Do it right if you’re going to spend the time planting something. That entails adding compost to our clay soils. Let’s not claim improper planting techniques the cause of mopheads failing to bloom since hydrangeas have enough difficulties now. All of this contributes to the health of the plant.
Minimal Pruning: 3
The dormant stems are unsightly in March and April, especially if new growth is emerging close to the plant’s base. By mid to late spring, any stem that has not begun to grow can be cut out. It is advisable to prune as little as possible or not at all because cutting any stem that is living could result in the removal of flower buds.
4. Eat frequently
We are placing a lot of demands on these titans. There is a lot of energy required for blooms from May through September. Your hydrangeas require frequent feeding. From March through August, Fertilome Premium Bedding Plant Food should be administered sparingly once per month. With a high phosphorus fertilizer, that translates to six times in the spring and summer.
5. Mulch in the summer.
This action lessens stress. Mulch helps the soil retain moisture and keeps it cooler. Additionally, as mulch (and compost) breaks down, it feeds soil bacteria that are essential for the release of nutrients to the roots of hydrangeas.
6) Extensive Watering (but only 1-2 times per week)
All plants must receive thorough, but infrequent, watering. Mophead hydrangeas in particular must receive this care. A 3 gallon shrub should receive 3 to 6 gallons of water each time it is watered if it was planted. Then, only once a week of watering is required because it needs time to dry out between waterings (2 times per week only during very hot, dry times). Keep in mind that a shrub may wilt on hot days, but this does not mean that the plant is dry.
Mulch throughout the winter.
If exposed to freezing temperatures for an extended amount of time, flower buds may freeze out. The shrub’s stems should be stuffed with leaves, and the base should be covered with a mound of leaves or bark mulch that is 12–18 inches high and encloses the majority of the newly created buds. The flower buds need more than just a fresh two-layer mulch covering to be shielded from the cold’s destructive effects. Although straw, burlap, and cloth are other options, most individuals already have access to a lot of leaves. Around Thanksgiving, this covering should be installed, and it needs to be taken down by mid-March (St. Patrick’s Day).
Obtaining “blue hydrangeas”
Only acidic soils produce the blue color on changeable varieties (not all pink hydrangeas can turn blue). To acidify our limy soils, add sulfur. Since aluminum has been shown to accentuate the blue coloring, aluminum sulfate is advised. Sometimes, as in this picture, a shrub will display blue, mauve, and pink all at once. This is because the aluminum sulfate was applied unevenly, the plant was unable to absorb the acidifier, or the plant was undergoing a change. Regardless, the plant is successfully blossoming!

They are hardy
The species of hydrangea most tolerant of freezing temperatures is the panicle. They are dependable shrubs or tiny trees that thrive with little effort. Their sturdy, reddish-brown branches range from being straight to arching and occasionally bow from the weight of the enormous blossoms. Although something closer to 6 or 8 feet tall and wide is more typical, something up to 15 feet tall and wide is possible. Panicle hydrangeas are typically too large for small gardens, but anybody may enjoy them with careful pruning or by picking a tiny variety like ‘Dharuma’ or Quick FireTM.
Pruning doesn’t affect bloom
Panicle hydrangeas don’t mind being clipped, unlike bigleaf hydrangeas (H. macrophylla cvs., Zones 69). Typically in early spring, I advise trimming the plants back by about half of their height before the leaves appear, though this is optional if you have space for a larger plant. Due to space limitations in the trial beds, we had to start trimming, but the better habits and results we saw afterward encouraged us to keep doing it. The size of the hydrangeas with annual pruning is depicted in the chart below. Contrary to many bigleaf varieties, panicle hydrangeas bloom on new wood, thus trimming won’t stop them from producing blooms and might even make them bigger. Annual trimming, in contrast to some accounts, did not promote long, feeble stems that were unable to sustain the weighty blossoms. All the cultivars, with the exception of “Dolly,” were robust enough to support their blossoms.
Flower type and size vary
Panicle hydrangeas produce a mixture of beautiful, sterile florets and frothy, fertile florets in their flowers. The showy florets, which vary in size and number depending on the cultivar, create the protracted bloom show, which is accentuated by a transformation from white to various pink tones. Unsurprisingly, the breeding trend has been to enhance the pink hue of the wilting blooms. I employ the words “To distinguish between the two floral varieties of panicle hydrangea, use the terms lacy and “mop.” In contrast, Lacy describes an open panicle with showy florets scattered throughout the fertile flowers “Mop is a sign of an excess of colorful florets with fertile florets buried beneath.
Watch the pHbut don’t worry about deer
I discovered that the alkaline nature of our soils at the Chicago Botanic Garden, particularly in hot, dry weather, may contribute to panicle hydrangea foliar chlorosis. Consistent watering will guarantee healthier foliage and more robust bloom output in hot conditions. Panicle hydrangeas are resilient to urban environments and rarely encounter pests or illnesses. While some cultivars are frequently praised for their mildew tolerance, none of our plants ever developed powdery mildew. Deer also favor bigleaf hydrangeas, but they usually show less interest in panicle varieties.
They have some winter interest
I’m not crazy about going into detail about a plant’s winter characteristics, but I disagree with detractors who claim that panicle hydrangea lacks any winter appeal. When rimmed with frost or covered in snow, the faded brown blossoms add some color and structural interest. I prefer to leave them on till spring because I’m a lazy gardener at heart and I’ll be pruning the branches anyway. When the crispy panicles break off and roll across the garden like tiny tumbleweeds, it’s entertaining.
