Lacecap hydrangeas have flower heads that resemble flat caps with frilly edges, giving the bushes their peculiar but fitting name. Lacecap hydrangeas, like mophead hydrangeas, are members of the Japan-native bigleaf hydrangea species (Hydrangea macrophylla).
While all lacecap hydrangeas have a disk of small, showy flowers surrounding by larger, lacy blossoms, the size, color, and timing of the shrubs’ blooms vary. The huge flower heads are set against a luxuriant background of broad, dark green, serrated leaves. These bushes, like the majority of hydrangeas, grow quickly, gaining 2 feet or more on average every year. Fall or early spring are the best times to plant.
How big can you grow lacecap hydrangeas?
Mophead blossoms are spherical, but the flower heads of lacecaps are flat. While mophead only refers to one species, lacecap blooms are seen in a variety of species (Hydrangea macrophylla).
Should you deadhead lacecap hydrangea?
Although it is not necessary to deadhead, you can clean up plants by removing wasted blossoms. For winter appeal, many gardeners leave flowers in bloom throughout the fall.
Why is my lacecap hydrangea not flowering?
Several variables, such as the following, can contribute to poor flowering:
- excessive shade
- incorrect pruning
- Crowding
- Over-fertilizing
- not enough nutrients
Increase sunlight, modify branch thinning and pruning schedules, and, as necessary, alter fertilization or soil additives.
Do I need to prune my lacecap hydrangea?
The first step in taking good care of lacecap hydrangeas is to ensure that your shrub receives adequate, yet moderate, water. These bushes enjoy regular hydration, but only if the water that is not used drains well from the soil. Muddy soil does not work well for lacecaps.
Evenly moist soil is preferred by these hydrangeas. Applying a thin layer of organic mulch to the soil near the roots of the hydrangea can assist the soil retain moisture. The hydrangea stems shouldn’t be within a few inches (8 cm) of the mulch.
Your care regimen for lacecap hydrangeas includes fertilizer. Use organic compost every year or use a balanced (10-10-10) fertilizer as directed on the box.
Snip the longer flowering shoots to a lower bud as soon as the plant has finished flowering. “Deadheading” encourages your plant to produce flowers all summer long. More thorough pruning might be done if you wish to manage the plant’s size. Cut at a bud to remove up to one-third of each stem.
According to information on lacecap hydrangeas, these plants may withstand heavy trimming. Trim a third of the stems at ground level to revive an older lacecap shrub that doesn’t flower frequently. Pick the oldest stems to remove and do this in the late winter.
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.
What hue do lacecap hydrangeas have?
The blossoms of lacecap hydrangeas (Hydrangea macrophylla normalis) are distinctive. The bloom forms a ring with clusters of tiny fertile florets and dispersed showy sterile florets.
Depending on the pH of the soil, the blossoms of hydrangea macrophylla (mopheads) are often pink, blue, or purple in color. By adjusting the pH of the soil, you may also alter the flower’s color to make it more blue or pink, depending on your preferences.
These unusual flowers do best in regions with morning sunlight and afternoon shade because they bloom from early summer through late October. To beautify your deck or porch, you can also grow these in garden planters.
Where should lacecap hydrangeas be planted?
The best place to plant lacecap hydrangeas is where they will receive both part-shade and part-sun. Ideal location would have morning sun and afternoon shade.
Are hardy lacecap hydrangeas?
With their flat flowerheads that have a center of tiny, clustered flowers encircled by a ring of spectacular florets, lacecap hydrangeas are easily identified.
Lacecap hydrangeas tend to be tougher than mophead hydrangeas and can optionally be deadheaded in the fall. Alternately, postpone this task until spring. Lacecap hydrangeas just only a small amount of trimming to put on a good display; in late winter or early spring, clip a couple of the oldest stems all the way down to the ground.
Make sure not to plant any hydrangea too deeply while planting it. Instead, bury them at the same depth as the soil in the container they came in.
What occurs if hydrangeas are not pruned?
If and when you prune is the key to happy, healthy hydrangea flowers. Of course, fertilizing and offering the ideal environment have a lot to recommend them. However, if you don’t prune properly, your efforts will be in vain. Deadheading is not the same as trimming. Pruning refers to more drastic cutting to preserve shape or remove dead growth. However, feel free to discard spent blossoms or cut fresh ones to use in arrangements.
Hydrangeas can bloom on either fresh wood or old wood, depending on the species. The wood from which they blossom determines whether and when to prune.
Old wood-blooming hydrangeas do not require pruning and benefit from it. They’ll blossom more abundantly the next season if you leave them alone. But feel free to deadhead or gently thin. Just keep in mind that while new growth may appear, it won’t bloom until the following season. In our region, four different species blossom on aged wood. Additionally, they are not limited to the hues displayed here.
Climb using suckers. On your wall or trellis, resist the desire to remove the dormant growth.
The flower heads are more conical in appearance, and the leaves are large and resemble oak leaves. It’s a pleasant surprise for a hydrangea when its leaves turn reddish-orange in the fall.
They are very comparable to lacecap types, but smaller and with more compact leaves.
Pruning should be done in late winter or early spring on hydrangeas that bloom on new wood. Trim back to two feet to prune to shape. The next season’s blossoms are produced by strong, fresh growth that is encouraged by trimming. In our region, there are two types that bloom on fresh wood. They are also not restricted to the colors displayed.
Oakleaf variants are not included in cone-shaped blooms. Keep the blooms on throughout the winter to provide interest; even dried out, they are quite lovely.
regarded as a wild kind. They often have smaller blooms and leaves than Bigleaf variants and are completely white. They enjoy full sun and can grow very tall.
Knowing whether or when to prune now will help you avoid the disappointment of a hydrangea that doesn’t blossom. Don’t forget that a robust shrub will produce more gorgeous blossoms if it has well-draining soil and good organic fertilizer. Come on in, and we’ll show you where to go to develop your green thumb.

Frost damage or poor pruning are the two main causes of Lacecap Hydrangeas (Hydrangea macrophylla). The Lacecap hydrangea bloom buds are vulnerable to frost damage since they develop their buds from August through September. Using a cultivar that is a little more hardy is about all you can do to combat this kind of blooming issue. However, you have complete control over this issue if trimming is the root of the absence of blooms. Deheading lacecap hydrangeas as soon as they finish blooming is advised, and true pruning is rarely necessary. If you must prune your hydrangea, stick to the excellent advice I discovered at Hydrangeas! Hydrangeas.
Hydrangeas don’t blossom for 2 minor reasons: not enough sunlight and not enough nutrition. Morning sun and afternoon shade are great for hydrangeas. Additionally, they may grow in drier settings, however this does prevent blooming. Ensure that your hydrangeas receive a half-day of sunlight. Once or twice during the summer, treat your hydrangeas using a balanced slow-release fertilizer. You should fertilize your hydrangeas in May and July. Fertilize no later than August.
Hopefully you’ll be able to identify the cause of your hydrangea’s lack of blooms and find a solution.
Is new wood better for lacecap hydrangeas to grow on?
Flowers on lacecap hydrangeas resemble a circle of closed buds encircled by open petals. In truth, the outer showy petals are infertile and only serve to draw pollinators; the unopened buds are the fruitful flowers carrying pollen.
Because lacecap hydrangeas flower on old wood, you can prune the shrub after it has finished blooming to shape and control it. The flowering will, however, start to fade after three years. Each spring, cut out one-third of the oldest branches to maintain healthy lacecap bloom. This will promote annual new growth while preserving some older growth for floral production. After the plant has flowered, if you wish to regulate its size, you can also prune the tips of the remaining branches.

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 amendments.
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.
