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.
The Authentic Hydrangea of Endless Summer
A gorgeous game-changer! The first continuously flowering hydrangea was called the Original Endless Summer. It’s also simple to maintain. Its season-long color-changing blossoms will amaze you.
late spring to early fall for blooms. Depending on the soil’s pH, blooms might be blue, purple, or pink.
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.
Which hydrangeas have continuous blooming?
Endless Summer Hydrangeas live true to their name, producing enormous pink or blue mophead blooms all summer long on both new and old wood.
Endless Summer Hydrangeas are distinctive and raise the bar for the common hydrangea. Both old and new wood can be used to grow their gigantic, striking blossoms, allowing for an exceptionally lengthy flowering season and the possibility of reblooms.

Is there a hydrangea with continuous summer blooms?
One of the more uncommon types that produces blooms on both old and new wood is the appropriately called Endless Summer hydrangea (Hydrangea macrophylla ‘Bailmer’ Endless Summer), also known as bigleaf hydrangea, which is grown in U.S. Department of Agriculture plant hardiness zones 4 to 9. However, according to the Missouri Botanical Garden, it doesn’t begin to bloom until July. Consider the Hills-of-Snow hydrangea (Hydrangea arborescens ‘Grandiflora’) as a garden partner to fill in the void. the Missouri Botanical Garden claims. In zones 3 to 9, it blooms from June through August. According to the Missouri Botanical Garden, the Oakleaf hydrangea (Hydrangea quercifolia), hardy in zones 5 to 9, is a wonderful choice for a complimentary cultivar because it blooms only on old growth, in contrast to the Hills-of-Snow hydrangea’s flowers, which only occur on new growth. There are numerous combinations between the various hydrangea varieties. You’ll have a consistent, luxuriant summer display if you choose your plants wisely.
How are Endless Summer hydrangeas maintained in bloom?

How do you get Endless Summer hydrangeas to bloom?
Endless Summer hydrangeas appreciate dappled shade in the afternoon and morning sun. It may be too hot and intense for the blossoms to form if they are placed in full sun. Additionally, excessive fertilization and watering of your plants can prevent blooming.
An eternal hydrangea is what?
24-36″ wide by 30-36″ high Continuous Revolution Mophead hydrangeas like Hydrangea have enormous, multicolored pom-pom blossoms. Pink, purple, blue, and multicolored flowers can all be present on one plant at once. Everlasting is a relatively compact hydrangea that is at home in container gardens and at the front of perennial borders. It was first developed for the cut flower market. Since the stems are strong, the weight of the blossoms won’t cause them to flop. Blooms persist a long time on the plant and in vases, as the name would imply. Gardeners in cooler climates can be sure to get flowers because this hydrangea blooms on both fresh and old growth. Spring and late summer blooming are common for plants in warmer climates. Plant in medium-moist, well-drained soil with full sun to light shade. This hydrangea’s blossom colors can change according on the pH, with higher pH soils producing more pink-purple blooms and lower pH soils favoring more blue-to-purple blooms. After the plant has finished blooming in the spring or, in colder climates, after it has begun to grow once more in the spring, prune.
About Hydrangeas
Native to the US and Asia, hydrangea plants produce colorful flowers all summer long. There are numerous kinds, each with unique bloom colors, flower shapes, overall heights and spreads, levels of winter hardiness, and container-growability.
What exactly does it imply when it says “Blooms on old/new wood” and what does that have to do with winter?
On old wood, also known as “last year’s growth,” some hydrangeas generate buds that will eventually blossom; on fresh wood, commonly known as “this year’s growth;” and on both old and new wood, in the case of other hydrangeas. This information is particularly helpful for gardeners in colder climates who might lose parts of their hydrangea branches to breakage from heavy snow and ice or who might witness growing buds being killed off by late spring frosts.
These gardeners can miss out on hydrangea blossoms the following summer if they lose young buds and old growth branches. A further measure of assurance is to select a kind that blooms on new wood (or both types of growth), which ensures that your shrub will continue to bear flowers come summer, no matter how cold your winters and late springs are.
Similar to this, warm-climate gardeners who select hydrangea kinds that only bloom on new wood must make it a point to prune their shrubs to promote the development of new buds. Undoubtedly a straightforward chore, but one that needs to be kept in mind.
The majority of hydrangea bloom colors are closely related to the pH and mineral composition of your soil. The finest results will come from planting in containers since you can set the ideal soil conditions at planting time and get very vibrant hues. Changing the soil’s pH in a garden bed is possible, but it frequently takes more than one season to observe benefits. Smooth hydrangeas (Hydrangea arborescens), which are native, cannot have their color altered.
Flowers that range from purple to blue are produced by acid soils (those with a pH below 7), with the most acidic soils producing the bluest blooms. You can add sulfur to your soil to encourage the growth of blue hydrangea blooms, or you can mulch your plants with pine and/or cedar needles.
Pink blossoms grow in alkaline soils (with a pH above 7). Your blooms will be a darker shade of pink the more alkaline (or sweet) your soil is. Lime can be added to the area surrounding your growing space to achieve this. However, it is more challenging to make hydrangea flowers pink because most plants generally find it difficult to thrive in soils with a pH above 7.
Hydrangea Types
Regardless of their general kind, hydrangeas come in a variety of heights and bloom cycles nowadays. You can discover Panicles that do well in containers and Mopheads that bloom on fresh growth, for instance.
Mopheads: (Hydrangea macrophylla) The most popular (and least cold-hardy) kind of hydrangea, mopheads are distinguished by its large blooms, which come in two varieties: lacecaps and pom-poms. Mophead hydrangeas are also referred to as “Bigleaf” hydrangeas because of its huge foliage, which adds a lot of greenery to the yard.
Panicle: (Hydrangea paniculata) The Panicle hydrangea is distinguished by its enormous, conical blooms and exceptional cold resistance. They can withstand more sun than other types because to their arching branches and profusion of blossoms.
Snowball vs. smooth (Hydrangea arborescens) These shrubs, also referred to as “Wild” Hydrangeas, are indigenous to the eastern US. While their color cannot be changed by altering the pH of the soil, their flowers usually turn a pale green as fall approaches.
Mountain: (Hydrangea serrata) These hydrangeas are native to the mountains of Korea and Japan where they are known as “Tea of Heaven.” They are more compact than Mopheads and have delicate lacecap blooms and thinner foliage. They are renowned for their lengthy blooming season and somewhat weeping shape.
Oakleafs: (Hydrangea quercifolia) Oakleafs are native to the eastern and southeastern US and feature deeply lobed leaves that change significantly in color in the fall. With gorgeous, elongated blooms, it is extremely cold hardy.
How long does the hydrangea Endless Summer live?
Endless Summer hydrangeas have an extremely extended flowering season and despite their delicate appearance, they are a sturdy, winter-hardy species. The luxuriant ball of pink, blue, or white petals and glossy leaves was created by a Minnesota nursery in 2004. The deciduous shrub drops its leaves in the fall before going dormant, and its dark green foliage turns burgundy in the fall. One of the plant’s distinctive qualities is its capacity to produce blossoms that, with the addition of a soil amendment, can change color from blue to pink or from pink to blue. With the addition of aluminum sulfate, one kind, the BloomStruck, can change from blue to a deeper blue-purple.

From spring through summer, this shrub blooms with lovely blue or pink flowers. The pH of the soil, which may be changed in the early spring by employing an acid fertilizer, determines the color of the blooms. The shrub’s small size—4 feet tall and wide—will fit into practically any setting. excels as a specimen or accent plant. These also work well as cut flowers in bouquets.
