The huge, spectacular blossoms of hydrangeas add vibrant color to gardens and containers throughout the stifling summer heat. These adaptable shrubs are also terrific at giving garden beds and foundation plantings structure, and they make excellent hedges. There is a cultivar of hydrangea for every garden, with sizes varying from container pot examples to 8-footers and hues spanning from pure white to reddish purple to traditional blue.
We thought it would be interesting to review the various types of hydrangeas as gardeners plot and plan what to add to their spring planting list.
Since it blooms on fresh wood and is not affected by late spring frosts, Hydrangea arborescens is a wonderful choice for cooler climates. Even in light shade, plants can survive.
China and Japan were the first countries to cultivate this species. Many species can withstand wind and salt spray. Fortunately, new Hydrangea introductions are more likely to flower on both new growth and stems that are at least a year old, ensuring flowers even after a harsh winter for gardeners in colder climates.
Since H. paniculata blooms bloom on young wood, it is likely the most frost-resistant Hydrangea of them all. Plants typically produce enormous, conical flowers.
The American native oakleaf hydrangea has tall, cone-shaped blooms. It has huge, broadly lobbed leaves that look stunning in the fall.
This species, which is indigenous to the mountains of Japan and Korea, favors milder environments. Some types’ flower colors are influenced by the pH of the soil.
Do hydrangeas require wind protection?
Hydrangea plants are stressed by brisk, drying winds in both the summer and the winter. Branch breaking and soil drying winter winds can harm latent roots. Especially from the bigleaf hydrangea cultivars (Hydrangea macrophylla), which are hardy in USDA zones 6 through 9, hot summer winds cause moisture to escape too quickly. Although it’s best to place hydrangeas away from the direction of the wind, you may offer some protection by covering the side that faces the wind when it’s windy. Put up a structure resembling the one used for sun protection, but place it so it blocks the wind. Remove the cover as soon as you can to avoid having it permanently obscure the sun.
How can I shield the wind from my hydrangeas?
The majority of defense strategies begin with a frame around the flower. This can take the form of strong stakes encircled by burlap, chicken wire, or any material that allows air to flow (Plastic is not recommended although some find it useful).
The sketch to the right depicts a dormant hydrangea enclosed in a wire cage, and you will certainly want to acquire a copy for your art collection. (One reader suggested using cardboard to line the interior of this cage.)
The box is then filled with an insulating material, such as pine straw, oak leaves, or something similar. Avoid breaking any of the branch tips, as this are where the flower buds have already developed. (One reader advised wrapping insulating material across the entire cage at this point.) Until the last possible frost has passed, this needs to be left on the hydrangea throughout the winter and into the spring. The hydrangea will already be leafing out when it is exposed.
It’s crucial to cover the extremities of the branches throughout the winter because hydrangeas frequently place their blossoms there. The majority of insulating materials need to be replaced or fastened in place because they tend to pack down a little throughout the winter and expose the branch tips.
Belgian hydrangea specialist Luc Balemans issues a warning that certain winter covers (like the one on the left) may scrape the ends of the branches off under windy conditions, which will then rub off the bloom buds. Before covering, a layer of leaves or other material should be used to preserve these crucial bloom buds at the extremities of the branches.
As was already indicated, leaves frequently settle throughout the winter, exposing tender buds. One gardener claims that because oak leaves don’t compact like other materials, they provide for exceptionally good insulation. An additional gardener advised storing extra bags of leaves in a location where they won’t freeze. The leaf insulation can then be refreshed with these when the winter settles in. We were able to uncover some decent selections online for individuals who don’t have time to visit their neighborhood garden center or are searching for something a little less expensive.

What is the ideal location to plant hydrangeas?
Learning the fundamentals of how to plant hydrangeas can help you save time and money, just like with most other items in your garden. You’ll improve your chances of enjoying big, vibrant hydrangea flowers for years to come by picking the appropriate site, getting the soil just right, and planting correctly.
When should I plant hydrangeas?
The best time to grow hydrangeas is in the fall, followed by early spring. The goal is to provide the shrub lots of time to develop a strong root system before it blooms. Early in the day or late in the day are the ideal times to plant. The day’s cooler hours provide relief from heat exhaustion. Water new plants frequently until they get established.
Locations to plant hydrangeas
The first step is knowing where to grow hydrangea plants. Hydrangeas are frequently grown in beds adjacent to houses or fences. This is so because hydrangeas prefer the mild early sun to the hot afternoon sun. A protected area with sunny mornings and shaded afternoons is the ideal spot to plant hydrangeas. This is frequently found on the north or south side of a house. Avoid planting underneath trees since it could cause competition for nutrients and water. Flowers and leaves can both be destroyed by strong winds.
hydrangea-friendly soil
The soil needs to be rich in organic matter for hydrangeas to thrive. Drainage is important. Although hydrangeas prefer damp soil, they cannot stand standing water. Root rot can be brought on by wet, poorly draining soils. Your hydrangeas could pass away in a matter of weeks. Consider adding a lot of compost to your heavy soil before planting to increase the soil’s quality.
Methods for planting hydrangeas
Simply dig planting holes that are 2 feet wider than the root ball for planting hydrangeas. So that your plant lies level with or just higher than the surrounding soil, match the depth of the hole to the size of the root ball. You can improve water drainage away from the plant’s base by making a small mound.
The best way to grow hydrangeas
Simple propagation methods can multiply a single hydrangea into several more. The optimal time to layer bigleaf and panicle hydrangeas is in the early to mid-summer. You only need to:
- Close to your hydrangea plant, make a tiny trench.
- Bend a branch such that the middle of the branch meets the earth in the trench (six to 12 inches of branch should extend past the trench).
- Where the branch meets the trench soil, make scuff marks on the bark.
- After the trench is filled, cover it with a paver, brick, or stone.
- The branch can be transplanted to a different area once it has established its own root system over time.
Hydrangeas with smooth or oakleaf leaves produce new growth from underground stems. Simply separate the baby plant from the main plant by digging it up. After then, it can be moved to a new spot.
Why do my hydrangeas keep tripping over?
When there are strong gusts, heavy rains, or an abundance of blooms, hydrangeas may topple over. Additionally, some hydrangeas simply have softer stems than others, which makes them more inclined to flop over.
The experts’ advice listed below can stop hydrangeas from toppling over:
Choose hydrangeas with stronger and thicker stems
Staking and the use of fences or trellises may be required to prevent flopping over in hydrangeas that bloom on new growths, such as the H. arborescens “Annabelle,” which can struggle to sustain the weight of its blossoms.
If you don’t want to invest the time and energy in that, you might want to think about hydrangeas with stronger stems, such as those that bloom on old wood.
When given time to mature, hydrangeas that bloom on ancient wood, such as the oakleaf hydrangea (H. quercifolia) and mophead hydrangea (H. macrophylla), will have woody stems that are more structurally sound than, say, the Annabelle.
Plant hydrangeas where are protected from heavy winds and storms
Your hydrangeas might suffer damage from strong winds and storms, especially if their stems aren’t thick or solid.
You can avoid them from flopping over due to heavy rain by planting them in a part of your garden that can be close to buildings that provide wind protection.
Plant hydrangeas at an appropriate distance from each other
Hydrangeas shouldn’t be placed too closely together or too far apart so that they can’t sustain one another.
They can naturally rely on one another for support when planted 3–4 feet apart, without being too close to one another.
It’s crucial to take into consideration your hydrangea’s natural spread as it reaches maturity. Avoid planting your hydrangea too close to other hydrangeas if it can grow to be 8 feet wide.
The shrub needs space for aeration in order to avoid a variety of foliage issues, such as fungal leaf infections.
Which hydrangea is the hardiest?
Everyone is aware of how hot hydrangeas are. But have you ever considered the direction that hydrangea breeding is taking? For a larger portion of the United States, increased hardiness and more dependable flowering may be the solution. Hydrangea macrophylla, a French hydrangea, is infamous for its unpredictable blooms. The flower buds are the source of this enigmatic absence of blossoms. Early in the fall, flower buds begin to form and overwinter. The plant won’t flower if the buds are harmed by an early autumn frost, cold winter temperatures, a late spring frost, or an improper pruning. They’ll be looking for a hydrangea that is sturdy and reliable as the gardening public (and garden center operators) start to realize that French hydrangeas are not reliable bloomers.
The plant that everyone has been hunting for might simply be the hardy hydrangea, Hydrangea paniculata. It blooms in the middle of summer and is a very hardy plant (USDA zone 4). In the early summer, it produces its buds. The flowers that bloom in July or August make wonderful bouquets when cut, and they may also be dried with ease. This hydrangea is quite simple to grow. Watch it grow by planting it in direct sunlight. It has no significant pests and may grow in a variety of soils. Plants can be severely pruned back in the early spring for extra-large blossoms.
Limelight Limelight Hydrangea is without a doubt the most attractive plant in my yard at the moment. Cool, a hydrangea with soft green flowers, but wouldn’t pink be even better, was my first thought when I first saw this plant in the Netherlands. After bringing the plant back to the United States, observing its development and the reactions of onlookers, I started to understand that this was a really unique plant. Six years of cultivating the plant have led me to the conclusion that it is one in a million.
Limelight has everything! It is not only absolutely stunning, but it can also perform. Gardeners have emailed me from Orlando to Manitoba to tell me how nicely this plant performs. A Chicago-based gardener told me that he incorporates the plant into each of his designs. Nearly all of his landscapes, according to him, are in new communities with little trees. Whether or whether it is reblooming, the bigleaf hydrangea (Hydrangea macrophylla) cannot tolerate the heat and sun. Under these circumstances, they merely fall to pieces. On the other side, Limelight prospers. It needs soils with either sun or shade, sand or clay. It has proven to be successful whether it is in the North or the South.
In addition to its exceptional adaptability and distinctive blossoms, this plant has a number of other qualities that make it a Proven Winner. It has extremely sturdy stems that support its enormous flowers even after a lot of rain. The Pee Gee Hydrangea, an outdated standard cultivar, should be composted because it is prone to falling over on its own. Additionally, if you pay great attention to Limelight, you’ll see that it continually sends up brand-new blossoms. It consistently blooms from mid-summer till the first frost. As a result, the older blooms shift from green to white to pink to burgundy, while fresh green blossoms are added to the color palette. This enormous variety of flower hues in the autumn is truly amazing. Want to produce something truly amazing? A 50-yard-long Limelight hedge (picture lower left) runs alongside the driveway of a friend of mine. People who are traveling at 55 mph through his neighborhood literally slam on their brakes when they see it.
Pieter Zwijnenburg, a highly recognized plant expert, created Limelight. A nursery is owned by Pieter and his wife Anja in Boskoop, the Netherlands. For this exceptionally unique plant, Pieter was given the Gold Medal Award by the Pennsylvania Horticulture Society.
Dr. Johan Van Huylenbroeek is the creator of Pinky Winky (picture above right). The white and pink two-toned flower heads that Pinky Winky produces in the middle of summer are what make it so unique and special. The huge, 16-inch-long flower heads, or panicles, start out white before swiftly turning pink at the base. Since the flowering is indeterminate, fresh white flowers keep pushing out from the panicle’s tip even as the older ones become a deep pink color. An added benefit is that the flower heads are supported straight and don’t droop by sturdy stalks. Additionally, the plant has dark green foliage, which serves as a lovely backdrop for its lovely blossoms. Pinky Winky flowers like other paniculata hydrangeas regardless of climate, soil, pH, or pruning. Use it to make a stunning floral hedge or as a specimen plant. Yes, Pinky Winky is an odd name for such a lovely plant, but once you hear it, you won’t soon forget it. When I questioned Johan about the name, he revealed that it was inspired by a Teletubbies character for kids. Despite its moniker, Pinky Winky Hydrangea has a sizable adult fan base. It stands out, is lovely, and is simple to grow.
From Jelena DeBelder of Belgium comes the lovely, resilient Little Lamb Hydrangea (pictures below). The smallest flower petals of any Hydrangea make Little Lamb special. These tiny, delicate flower heads, which resemble dancing lambs hovering above this small shrub, are tightly packed with these tiny, delicate flowers. This unique plant has summer blooms that continue into the fall. The pure white blooms brighten a garden and harmoniously complement all other hues. Use The Little Lamb in fresh or dried bouquets to create a distinctive floral arrangement. With consistent flowering and flower color regardless of soil pH or winter temperatures, this plant is simple to grow. The flowers are evenly spaced out, creating a really attractive plant and show.
A blaze of color and a breakthrough in hydrangeas, Quick Fire (pictures below) blooms months sooner than older kinds, extending the bloom period and attractiveness from early summer to autumn. This kind blooms earlier than other variations, and before other varieties even begin to flower, its blooms turn from white to a beautiful pinkish-red. a fascinating plant that is revolutionizing gardening. It doesn’t matter where you live or how you prune; this is a highly hardy variety that blooms consistently every year. No fussing or speculating, as with other Hydrangea.
