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 kind of hydrangea do I have, and how can I know?
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.

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.
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.

late spring to early fall for blooms. Depending on the soil’s pH, blooms might be blue, purple, or pink.
Which hydrangeas ought to be left unpruned?
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.
What hydrangea is the most beautiful?
Endless Summer BloomStruck Hydrangea, which can withstand extremes of heat and cold, is comparable to Summer Crush in that it consistently blooms on both old and new growth. From early summer until late fall, it will produce lovely blooms. Depending on the soil pH, BloomStruck has deep blue-purple or deep pink flowers with super-strong red stalks and a more compact growth habit.
Let’s Dance Can Do
Let’s Dance, We Can As opposed to most bigleaf hydrangeas, which only produce flower buds at the top of the stem, hydrangeas produce flower buds all the way down the stem. This means that even if there is a late-season frost, flower buds may still form in the early summer. Depending on the soil, the plant has gorgeous lavender or strawberry pink lacecap blooms.
Limelight Prime
Large blooms on limelight hydrangeas that shine in direct sunlight are their trademark. From bud to bloom and beyond, the new Limelight Prime panicle hydrangea outperforms the old Limelight in every way. With bolder, better flower color and much stronger stems, it blooms earlier. It is also one of the easiest hydrangeas to grow and is a more useful, compact size.
Fire Light Tidbit
The smallest and cleanest panicle hydrangea is Fire Light Tidbit. Its height and width are only 2 to 3 feet, yet it has a lot of low-maintenance beauty. It has large, dense panicles of early- to mid-summer white mophead blooms that almost completely cover the textured green foliage. It produces a compact, mounded plant that looks great in landscapes, flower gardens, and even in containers because to its strong, thick stems.
What type of hydrangea is the simplest to grow?
Why are oakleaf hydrangeas so straightforward? They are not particular! In comparison to other hydrangeas, oakleaf hydrangeas can withstand cooler temperatures, greater sunlight, drought, and pests and diseases, and they do better in sandy soil.

Which hydrangeas are the hardiest?
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.
Where should hydrangeas be planted for greatest results?
Plant hydrangeas close to a water source in an area with lots of light. Choose a location in the South where there is morning sun and afternoon shade. Hydrangeas can tolerate full-day sun in the north.
When do hydrangeas bloom?
The type, cultivar, planting zone, and hydrangea blooming season all affect when they bloom. The majority of hydrangeas with new growth form buds in the early summer in preparation for blooming the next spring, summer, and early fall. Hydrangeas may stop flowering in the heat of the summer in hot locations, but they will blossom again in the fall.
How do you cut back hydrangeas?
Hydrangea plants don’t require pruning if they are allowed plenty of room to develop in the garden. Only the periodic clearance of dead wood is necessary.
Do you need to deadhead hydrangeas?
Your hydrangeas will continue to bloom into the fall if you deadhead them. Hydrangeas make wonderful cut flowers, so there’s no need to wait until the flower wilts. Leave the early fall blossoms alone so they can fade naturally. In the days leading up to your freeze date, you don’t want to promote new growth.
How do you control hydrangea color?
The distinction of hydrangeas is that you can modify their color. But keep in mind that not all hydrangea varieties can change their color. H. macrophylla, a species of bigleaf hydrangea, responds to changes in soil pH. Hydrangeas can absorb aluminum thanks to a low soil pH, which gives the blossoms a lovely blue hue. Reduce the pH of your soil by mixing in sulfur or peat moss to enhance the number of blue hydrangea flowers. Throughout the growth season, you can keep amending your soil with extra aluminum sulfate. When you add ground limestone to boost the pH, pink and red blooms shine.
You may precisely modify your hydrangea color using a soil pH test. To avoid the plant from being harmed, keep the pH level below 7.5. In the fall, all hydrangeas will naturally fade regardless of the modifications you’ve made. Don’t worry, the plant will display vibrant, new blossoms once more in the spring.
Can hydrangeas grow in shade?
Although they won’t blossom in complete shade, hydrangeas prefer dappled or infrequent shade. How much sun do hydrangeas need is more important to consider than whether they love the sun or the shade. Your hydrangeas require more sunlight the further north in your garden you are. A general guideline is six hours of sunlight each day. However, southern hydrangeas can thrive with just three hours of sunlight per day.
Can hydrangeas grow in full sun?
While hydrangeas prefer morning sun, they struggle in the hot, afternoon sun. For these gorgeous creatures, partial shade in the later hours of the day is optimal.
Can you grow hydrangeas in pots?
Even if you don’t have enough room in your garden to cultivate hydrangeas, you can still enjoy these lovely blossoms by learning how to grow hydrangea in a pot. As long as you follow the fundamentals of caring for hydrangeas, the procedure is rather straightforward. Select a pot with at least an 18-inch diameter to accommodate the mature size of the particular hydrangea you are growing. In order to maintain the constant moisture level that hydrangeas demand, look for non-porous containers. Excess water will be able to adequately drain thanks to drainage holes. Consider growing dwarf hydrangeas like Buttons ‘n Bows, Mini Penny, and Little Lime.
How do you keep hydrangeas from wilting?
Morning irrigation on a regular basis can assist stop withering. Some hydrangea cultivars simply can’t stand the heat. No matter how much water you give them, they will begin to wilt in the afternoon heat. Mulch applied in layers can help soil retain moisture and stay cool. You shouldn’t be concerned if your hydrangeas bloom again once the day cools. A little midday wilting is preferable to overwatering and drowning your hydrangeas.
