Hydrangea quercifolia, often known as oakleaf hydrangea, satisfies all the criteria for a superior garden shrub, including year-round interest, stunning blooms, prolonged bloom duration, intriguing leaves, and ease of maintenance, including pruning.
The Southeast is home to oakleaf hydrangea, one of just a few Hydrangea species that are endemic to the United States. There, it grows naturally along riverbanks and in moist woodlands.
According to Lisa Anderson, a research geneticist at the United States National Arboretum who specializes on Hydrangea quercifolia, “it’s great for the garden because it’s a no-fuss plant. Although full sun brings out the greatest flowering and fall color in this hydrangea, it doesn’t require a lot of light, and once it’s established, it can withstand drought conditions despite preferring moderate maintenance. And it is quite beautiful.
According to Lisa, oakleaf hydrangeas add interest to the landscape all year long.
Tall, eye-catching blooms and a wide range of foliage hues are present in the spring and summer; rich reddish-purple leaves and regal dried flower heads are present in the fall; and throughout the winter, the peeling bark adds texture.
Companion Plants for Oakleaf Hydrangeas Because of this sustained attention, incorporating the shrub into the garden is not too difficult. Whether white or pink, its summer blooms are substantial and endure for a long time. As lower-growing shrubs and herbaceous plants come into and out of bloom, the large, bold-textured leaves—from which they derived their scientific epithet and common name: quercifolia, oakleaf—provide a pleasing contrast.
Spring-flowering bulbs were suggested by Stacey Hirvela of Spring Meadow Company, the nursery that produces Proven Winners ColorChoice Shrubs, as the appropriate early partner. She remarked, “The oakleaf hydrangea’s spring foliage is very unusual. For example, by planting some colorful daffodils around the plants, you may highlight their fuzzy white leaf buds. She suggested foliage perennials in the later spring and summer to contrast with the huge leaves of the hydrangea.
Given that they have a generally coarse texture, Stacey remarked, “I believe they look really good with fine-textured plants like ferns, particularly native ferns, and especially larger ones that are more in proportion with the shrub. She proposed that the shrub’s base be surrounded by Japanese forest grass (Hakonechloa macra). In order to highlight their spectacular branching and peeling bark in winter, she continued, it’s also a good idea to place them in front of an evergreen.
The size of the plant, which may grow to be 12 feet tall and wide, may be the only drawback to H. quercifolia that you could find. Thanks to breeders’ efforts, this unusual hydrangea may now be found in gardens of all sizes. Gatsby Gal, a cultivar from Proven Winners, reaches a height of five to six feet, for example. At six to eight feet, Gatsby Moon gets bigger. The smallest possibilities are “Munchkin,” “Pee Wee,” and “Sikes Dwarf,” remaining between three and four feet tall and wide.
- Native to the moist woodlands and riverbanks in the Southeast of the United States is the hydrangea quercifolia.
- a location with full to partial shade
- The most flowers and richest fall leaf color are cultivated in full light.
- Ensure adequate drainage and moderate moisture
- Oakleaf forms flower buds in the late summer, which bloom the following year, much like the bigleaf hydrangea (H. macrophylla). If you prune it in the fall, winter, or spring, the flower buds will be lost.
- When pruning, wait until right after the plant has flowered.
- USDA Zones 69 to 69, with some varieties graded to Zone 5
- A thick winter mulch or burlap cover is advised in Zones 5 and 6 as well as a position protected from winter winds because a northern winter’s cold might harm flower buds or destroy stems to the ground.
How to Purchase and Plant Oakleaf Hydrangea The following advise was given by Stacey Hirvela of Spring Meadow Nursery:
1. Oakleaf hydrangeas resemble wild creatures in certain ways. They are often more expensive than other species since they grow slowly in pots. They object to the container environment’s constrained root space as well. If an oakleaf hydrangea isn’t absolutely stunning in the container, don’t avoid it. Once they are buried, they may really shine, forming healthier habits and expanding more swiftly.
2. Hydrangeas are frequently associated with shade-loving plants. While all hydrangeas will thrive in the shade, for the healthiest stems, most flowers, and greatest leaf and flower color, we do advise at least a half-day of sun or filtered shade all day. Even though oakleaf hydrangeas appear to thrive in more shade than other hydrangea varieties, less than four hours of direct sunlight every day won’t allow them to produce as many flowers or, more importantly, their greatest fall color.
Can an oak leaf hydrangea be planted in a pot?
Oakleaf hydrangeas do not enjoy the constrained space of a container or pot and may not grow, in contrast to other hydrangeas, especially varieties developed for container planting. It is strongly advised against potting this plant.
Can hydrangeas survive in pots?
Selecting the appropriate-sized planter for your hydrangea is the first step in planting. Because their roots are vigorous and quickly fill smaller containers, hydrangeas do not grow well in smaller containers. Additionally, smaller containers dry out far too quickly for hydrangeas. Generally speaking, we advise purchasing a medium to big planter that is at least 2 feet wide.
Make sure there are drainage holes at the bottom of the planter once you’ve chosen it. It is necessary for hydrangeas to be grown in pots because they will decay if the soil lacks adequate drainage. To aid in drainage, we also like to add a layer of rocks at the bottom. The most important stage for healthy plants is proper drainage.
You must then purchase soil made especially for planters. In containers, topsoil can occasionally fail to drain properly. Compost can be applied to the soil to provide additional nutrients.
Plant the hydrangea at the same depth in the soil as it was in the pot it was previously growing in when putting it in the pot. To water the planter without the water washing out the top, leave at least 2 inches between the top of the soil and the top of the planter. To assist the plant stay firmly in the pot, gently press down on the dirt around it to remove any air pockets.
Can you maintain a little oakleaf hydrangea?
Growing oakleaf hydrangeas shouldn’t be challenging if your hydrangea was planted properly. Once established, these natural shrubs are drought tolerant and nearly disease and pest-free.
According to literature about oakleaf hydrangeas, the plants can reach a height of 10 feet (3 meters) and a spread of 8 feet (2 meters). If you haven’t given the hydrangeas enough room to grow to their full size, you may need to start pruning them to keep them small enough for the area.
Oakleaf hydrangeas can benefit from pruning in order to grow into a full shrub. If this is what you want, pinch back new growth or otherwise reduce older growth. Don’t prune these shrubs until they are in bloom since they blossom on the growth from the previous year. As a result, they have more time to develop new buds that will blossom the next summer.
Which hydrangea varieties can be grown in pots?
These shrubs have a lengthy flowering period, and many of its cultivars bloom in the spring, summer, and fall “mophead
the preferred “Depending on the variety and growing conditions, bigleaf varieties (Hydrangea macrophylla) produce huge, spherical clusters of pink, blue, purple, or even bright green or red blooms.
Additionally, some H. macrophylla cultivars have tiny flowers that resemble lace that are encircled by bigger blossoms; these are known as lacecap hydrangeas.
Depending on the cultivar, H. macrophylla can flower on either old or new wood, and they are quite sensitive to the pH of the soil.
Plants that are grown in the appropriate pH range of 5.2 to 5.5 generally produce blue flowers. The blossoms will turn pink or mauve in soil that is more alkaline, in the range of 6.0 to 6.2.
Another common species, the panicle hydrangea (H. paniculata), is often white. Their flower heads resemble full ice cream cones, and as they age, the petals frequently become a lovely shade of pink.
Panicle variations can be pruned back in the winter and only bloom on fresh wood. They also don’t care much about soil pH, unlike bigleaf varieties, and can grow well in a range of 5.0 to 7.0.
The size and form of the flower head are quite similar to mopheads on shade-tolerant smooth hydrangeas (H. arborescens). However, the flowers themselves are smaller and always develop on fresh wood.
Although they are native to the Southeast of the United States, these towering shrubs thrive in Zones 3 through 9. Their initially cream-colored blossoms eventually become green.
Featured are mountain hydrangeas, H. serrata “with a center of small blossoms, lacecap-style blooms.
Similar to H. macrophylla, H. serrata blooms turn blue at lower pHs and pink at higher alkalinities.
The oakleaf hydrangea is the last species suitable for growing in containers (H. quercifolia).
As its name implies, this variety has foliage that resembles oak leaves, and in the fall, it turns scarlet. The white blooms are smaller and grow in cones “greater than in other species. The growing zones for oakleaf variants are 5 to 9.
Can hydrangeas in containers endure the winter?
Hydrangeas in potsWinter Care Bring potted plants indoors before the first frost for the greatest hydrangea winter protection. They can stay outside and be protected by covering the entire pot and plant if they are too heavy to transport.
How are hydrangeas kept alive in pots?
If you’ve ever received a hydrangea in a foil-wrapped pot, you likely loved it for a few of weeks before seeing it sadly wilt. You might conclude from it that hydrangeas are poor container plants.
Most hydrangeas that are given in pots as gifts do poorly because they are kept indoors for too long. Others perish because they were grown in a greenhouse and are not cold hardy in your region of the country, even if they are planted outside.
However, hydrangeas can make wonderful potted plants if you choose wisely. What you should know is as follows.
Potted Hydrangea
You can utilize hydrangeas in containers in your garden on stands, decks, or patios. This plant looks classy perched atop an antique column.
- Choose a location for the hydrangeas first. You may move them around, which is one of the benefits of growing them in pots. This also makes it simpler to provide hydrangeas with the ideal growing circumstances because many of them like morning sun and afternoon shade. Additionally, you can arrange them to beautify a patio or other area for a celebration or special event.
- If your pots won’t stay in the same spot all the time, search for containers with wheels on the bottom or think about durable, rolling plant stands. Don’t forget that after adding dirt and plants, containers can become rather heavy, and soaking them can make them even heavier.
- For your hydrangea, pick a large container with a diameter of at least 18 to 20 inches. The plant commonly wilts in small pots like the one your gift hydrangea arrived in since they typically dry out too quickly. Drill drainage holes into the bottom of your container if there aren’t any already. Rotting can result from water that accumulates around the roots.
- Next, pick a variety that is advised for your area. (This is a general guideline for growing any plant well.) To choose the best types for your yard, read plant tags or conduct online study. Some hydrangea varieties can grow in USDA zones 3 and 9, while the majority are hardy in zones 4 to 8.
- Although using miniature hydrangeas in pots isn’t required, you might wish to if you have a small yard. Not only do hydrangeas grow tall, but they also become bushy. If not, prepare to prune your plants as they develop. Be careful when conducting your research; see if your variety blooms on new or old wood. You’ll lose the flowers for the following year if you prune at the incorrect time of year.
- Use high-quality potting soil that contains organic materials rather than regular garden soil. If you want the hydrangea to continue growing, don’t plant it higher or deeper than it was in the pot it came in. Make sure there is space below the pot’s rim so you can water.
- To get rid of air pockets, gently compact the dirt close to the roots.
- Water your hydrangea well whenever the top inch or so of the potting soil feels dry. But being underwater is preferable to being overwatered. When they are thirsty, hydrangeas may wilt to let you know. However, this can stress them out, so check them every other day or so. You’ll eventually get a sense for how frequently to water. In times of drought or extreme heat, you might need to increase your watering.
- Although hydrangeas don’t require a lot of fertilizer, you can feed your plants once or twice a year with a commercially available composted manure, a 10-10-10 granular fertilizer, or a slow-release balanced fertilizer. If you reside in a warm environment, wait until after July or August to fertilize. Gardeners in the north can get away with applying fertilizer just once, in June or July. Feeding hydrangeas later, when they should be starting to go dormant for the winter, promotes fragile, fresh growth.
- If your plant already appears to be ill or unhealthy, don’t fertilize it—you’ll just increase its stress. Try to solve the issue instead.
Are hydrangeas better in the ground or in pots?
Maintaining hydrangeas in pots is easy, and they provide a beautiful addition to a deck or patio’s color and structure. Additionally, they go well with modern gardens as well as country gardens.
You already know that hydrangeas want moist, organically rich soil that doesn’t dry out over the summer if you’ve read up on how to cultivate them. They thrive best when planted directly into the ground because containers have a tendency to dry out much more quickly.
But that doesn’t mean you can’t use these blooms to make a lovely container arrangement. Simply make sure to take good care of them, choose your compost wisely, and plant them where they will thrive. Additionally, some kinds are better suited to these circumstances. Everything you need to know about taking care of hydrangeas in pots is included in this guide.
How long do hydrangeas in pots survive?
Temporary A temporary planting can be done in almost any container! You are ready to go as long as it can contain soil and has a hole (or several holes) large enough to let excess water out. This implies that you can make use of troughs, antique-style containers, or the DIY container you found on Pinterest.
Use AquaPots if you’re more of a laid-back grower. This top-notch, self-watering equipment makes growing hydrangeas in containers a snap. The containers themselves are stunning, but the hydrangeas also appear great and fresh because of the steady flow of water. This approach might truly save you time because it’s no secret that container gardening requires a little extra work due to the setup of drip irrigation or frequent hand watering. It should be noted that AquaPots are only suggested for short-term plantings in cold locations due to the risk of cracking if you don’t empty them before the first winter freeze.
Permanent If you reside in an area that gets frost, the container material is crucial. Pick a frost-resistant pot; many will have a sticker to indicate this. Just stay away from clay, terra cotta, or ceramic pots if you’re not sure if your container will work. When freezing temperatures come, containers that aren’t frostproof frequently break or shatter, leaving the roots of the plants exposed to the bitter cold.
If you’re fortunate enough to reside somewhere that doesn’t freeze, you can utilize AquaPots for long-term planting. Hydrangeas can really be planted in any clay, terra cotta, or ceramic container that catches your eye.
The size of your container is important since the plant’s roots will require space to expand while it is there. We’ve discovered that pots that are at least 16 to 24 inches broad and deep may frequently hold a sizable hydrangea for a few years.
Before planting the hydrangea, transfer any hefty containers—think elaborate and vintage—into position. Additionally, plan to have a dolly on hand to transport it easily if you want to overwinter it in a more protected location.
