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. The majority of mophead hydrangeas prefer a location with moist, well-drained soil and some afternoon shade in order to grow.
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 distinguishes lacecap from mophead hydrangea?
Known by their scientific name as Hydrangea macrophylla, bigleaf hydrangeas are the most common type 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.
What kind of hydrangea do I have, and how can I tell?
The aforementioned plant traits make it simple to distinguish between climbing and oakleaf hydrangeas, hence they will not be covered in this section.
Shape of the Flower Head
- A paniculata type is most likely present if the flower head is formed like a cone.
- It is either a macrophylla or an arborescens kind if the flower head resembles a ball or a flat disk. Visit the section on Flower Color.

Flower Color
- A macrophylla type is present if newly opened blooms feature blue, purple, or pink blossoms.
- An arborescens type is present if the flower buds initially seem green, then turn white, and finally turn green or greenish brown as they ripen.
- You likely have a macrophylla kind if the flowers are white when they first open and remain white as they age. Although they are less common, white flowered macrophylla varieties do occur.
Note: Recent breeding is beginning to develop arborescens with flowers that have a pink tint, such as “Eco Pink Puff.” Future cultivars should have a stronger version of this pink.
How should a mophead hydrangea be pruned?
What kind of gardener someone is depends on a variety of factors. We all have different cleaning habits. Some of us prefer to clean up in the spring, while others prefer to clean up in the fall. It’s the ideal time to break out your pruners and get to work if you like to prune in the spring. Hydrangea macrophylla is one of the plants that is frequently clipped at this time of year.
Whenever you prune hydrangeas, keep the following goals in mind:
- removing the previous season’s spent blossoms.
- Elimination of dead wood.
- removing some of the shrub’s leaves will help: older-than-three-year-old stems; large, intricate branches; Branches that cross in the middle and frequently rub against good stems; roots and stems that extend horizontally along the ground, enlarging the plant’s overall size.
- forming the shrub into a spherical, symmetrical, and natural-looking shape.
Take these actions:
- Look at the plant’s overall size and shape for a moment. Is it too big for the room it’s in? In foundation plantings, hydrangeas typically “Over time, consume the lawn. Instead of cutting the plant back to an unnatural shape, think about enlarging the bed to fit the mature growth of the plants. In “Nikko Blue” Particularly hydrangeas have a propensity to grow quite tall and wide, blocking windows and pressing up against home siding tiles. If you are struggling with enormous plants, think about replacing them with a smaller variety because it is impossible to keep a “Nikko Blue” Hydrangea from blooming every year and shorter than 4 feet.
- From the stem tips, remove all of the spent blooms. Always make pruning cuts slightly above a healthy cluster of buds. It is not necessary to “If there are no faded blooms to remove, tip branches. The plant’s topmost buds that overwinter have the ability to bloom. The plant could not flower at all if too much of the plant is removed.
- Remove all stems that are damaged or dead. Wherever feasible, it is desirable to entirely remove dead stems from the ground.
- Using the tips above, take away about a third of the stems’ total mass. As a result, the center of the plant receives more sunlight and air circulation, promoting the production of flower buds and vigorous new growth from the base.
- If you must, trim the shrub to get it below a window or railing no more than a few feet from the top. Remember that by the middle of the summer, the plant will swiftly revert to its normal size.
- Take a step back and evaluate your efforts. Finalize your cuts so that the bush is rounded and balanced.
The height of mophead hydrangeas.
In acidic soil, the mophead hydrangea’s blossoms are deep blue, and in more alkaline soil, they are magenta. In Zones 5 through 9, it grows to a height and width of three feet.
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!

What Are Reblooming Hydrangea?
Hydrangeas that rebloom allow gardeners in frigid locations the opportunity to enjoy hydrangea blossoms despite chilly winters. Reblooming hydrangeas have the unusual capacity to produce buds on both springtime new wood growth and falltime old wood. The plant can generate blooms on fresh growth even if cold weather damages flower buds, provided the damage is not too severe. The Let’s Dance, Bloom Struck, and Endless Summer hydrangea types all rebloom. These hydrangeas with mopheads and lacecaps, like Twist and Shout, Tuff Stuff, and Tiny Tuff Stuff, will bloom without much care. Nevertheless, routine trimming promotes new growth that can result in a better show.
Where to Plant Macrophylla Hydrangeas?
In gardens, flower mop sizes range from four to six inches, and when grown in containers, they can reach eight inches. Medium to deep green foliage has demonstrated good mildew resistance. The height and width of the plant increase by three to five feet. It prefers the sun, thrives in rich soil, and needs a lot of water.
Hydrangeas are prized as shrubs and border plants due to their size and thick foliage. They can be utilized as a backdrop for other flowering plants in your landscape or to establish boundaries or a planting “region.” These huge leaf hydrangeas need early morning sunlight and thrive in damp but well-drained soil. Mophead and lacecap varieties of macrophylla hydrangea shouldn’t be planted in dry, fully exposed places with high winds that could harm new spring growth.
Can I Plant Hydrangeas in the Sun?
Uncle’s Dunce The panicle and arborescence (smooth) types of hydrangeas serve as evidence. These people enjoy the sun. Although they enjoy the sun, these hydrangeas may also thrive in some shade. Both panicle and smooth hydrangeas, including the crimson Invincebelle Ruby, the white Annebelle, and the Incrediball, bloom in the late summer on new wood. In contrast to its well-known, shade-loving cousins, the macrophylla, or mop head hydrangea, which bloom on aged wood. The sun-loving hydrangea Hydrangea quercifolia, also called Oakleaf hydrangeas, including Alice and Ruby Slipper, bloom on old wood growth.
Which hydrangea has the most blooms?
Historically, hydrangeas only had one blooming season. No longer! You may now pick from a wide selection of hydrangeas that bloom all summer long. Even now, you can prune these.
With reblooming hydrangeas, you can enjoy blossoms from June until the first frost since they bloom on both new and old growth. They’ll keep blooming long after other perennials and bushes with flowers have finished. Long-lasting flowers in shades of blue, violet, pink, white, or chartreuse give any garden vibrant splashes of color.
These hydrangeas also pull off a spectacular act. The color of the hydrangea varies according to how acidic your soil is. Beautiful blue hydrangeas are quite simple to make. All you have to do is add Espoma’s Organic Soil Acidifier to your soil.
