The blossoms are the most important thing. Where I planted the Little Lime, it was so visible that I could see every step of blossom development.
The blossoms initially have a loose paniculata (cone) shape and are, well, lime green (yeah, it’s named well). As they age, they begin to change.
Bonus! Since it blooms on new wood, the plant continues to produce fresh lime green blossoms throughout the season, much like Endless Summer.
The blossoms begin to age with mauvy-pink tips that gradually fade to a greenish-white tint with faint pink highlights.
The fact that the majority of hydrangea kinds have flowers that change hues and tones throughout the season is one of my favorite things about them!
Growing the dwarf variety of Limelight is also recommended because it doesn’t seem to have the same problems with flopping and drooping stems as the larger shrub does.
The shrub is also almost “plant it and forget it.” All that is required in terms of maintenance is to apply a layer of compost that feeds the soil each year (over a covering of newspaper, of course), and then cut it in the spring.
How to Grow Little Lime Hydrangea
- Plant little lime in zones 3–8, well-drained soil that has been treated with compost, in a location that receives part shade and part sun (warmer climates should look for an area with afternoon shade).
- This can also be planted in a container, where it will maintain a height closer to 3 feet.
- When planting, spread a layer of compost that feeds the soil over the area, then cover it with newspaper and mulch to prevent weed growth.
- When it’s dry out, water frequently.
- To promote fresh blooms and robust stems, prune and shape the plant to 1-2 feet in late winter or early spring.
- Plant them about 4 feet apart if you want to make a hedge. They increase in height and width by 3 to 5 feet (though my experience with growing in a sunny location was the full five feet tall).
Decorating with Little Lime Hydrangea
The mature Little Lime hydrangea is incredibly simple to dry; simply cut the flowers and arrange them in containers to enjoy all winter long.
For our table, we constructed a straightforward long box out of reclaimed wood, decorated it with some fall décor, a few white small “Baby Boo” pumpkins, and Little Lime blossoms.
You can create a beautiful look for the porch that will endure the entire fall by adding some of the cut flowers to an old galvanized pot.
One year, I made a modest mantle out of historical green Ball canning jars, each with a single, sizable Little Lime blossom. Before all the pumpkins emerge, the shift from late summer to October should be simple and sweet.
In 2016, the Little Lime Hydrangea was selected as Landscape Plant of the Year, and I can definitely understand why!
Although I’m disappointed that I couldn’t put it in my new farmhouse landscaping (damn those pesky deer…), I will undoubtedly plant one in my enclosed garden so I may harvest some of the stunning blooms.
This article, which was first released in September 2012, has been updated.
How quickly does a small lime hydrangea expand?
The Little Lime Hydrangea attracts attention with its grouped, variegated blooms. Since it is a dwarf form of the Limelight Hydrangea, this panicle hydrangea bush is ideal for gardens with limited spaces.
Both raised garden beds and containers can be used to cultivate Hydrangea paniculata ‘Little Lime’. Despite its diminutive size, their cone-shaped blooms will stand tall and proud. Flowers will blossom in the summer with a delicate lime green colour, changing as the seasons do to pink and burgundy. In order to promote new growth and shorten the blooming period, deadhead spent flower blossoms in the winter or the early spring. Even after they have dried up, you may save your cut flowers to create a lasting bouquet.
Dark green foliage contrasts the colorful blossoms, giving the Little Lime Panicle Hydrangea shrub the appropriate amount of illumination to put on a show throughout the summer. Because it is a deciduous shrub, it will shed its green leaves in the fall and winter and enter a dormant state for the winter. This specimen was created by Proven Winners for mass plantings and foundation plantings.
LITTLE LIME HYDRANGEA CARE
The Dwarf Hydrangea Little Lime has an upright growth habit and can mature to a height and width of up to 5 feet. It can withstand droughts as well. It prefers morning light and afternoon shade and does best in loamy, moist, well-drained soil types. In hotter climes, scorching sunlight may cause the leaves and blooms to become brown.
Most of the United States can grow this flowering shrub in zones 3 to 8 on the Department of Agriculture’s plant hardiness map. great shrub border material. Little lime Hydrangea hedges should be spaced 3 feet apart. Anyone in North America may grow hydrangeas, which are enjoyable and gratifying to grow and have stunning lime blooms.
Early spring is the ideal time to put this Panicle Hydrangea bush so that it has time to set down roots before winter. The Little Lime hydrangea can grow up to 12 inches per year, and a spring fertilizer spray each year will aid in the development of their roots.
How To Prune Little Lime Hydrangea
Just below the flower crown, you can remove any outdated blossoms as well as any weaker canes at the base of the plant. Additionally, pruning older canes at the soil level will maintain healthy, abundant flowers. Your blooms will grow larger the closer you trim them to the earth.
When To Prune Little Lime Hydrangea
Before new growth or larger flower buds begin to form, little lime hydrangeas should be pruned in late winter or early spring. Cut the branches of your Little Lime Hydrangea 18–24 inches above the soil line if it is sagging to check for blooms on new wood.
Little Lime Hydrangea Companion Plants
The best evergreen shrubs to grow with hydrangeas include hollies, boxwoods, daylilies, and azaleas.
Check out our blog post on How to Prune a Little Lime Hydrangea into a Small Tree, as well as our hydrangea grow guide, Why is my hydrangea Wilting. You’re not into this pruning adventure, are you? The Limelight Hydrangea Tree is already available as a single trunk tree. Definitely a lovely, useful plant!
Do tiny lime hydrangeas require direct sunlight?
Each plant requires the following conditions to thrive: Full Sun (6+ hours), Part Sun (4-6 hours), and Full Shade (up to 4 hours).
Do Little Lime hydrangeas thrive in partial shade?
When fully grown, the Little Lime Hydrangea will have a spread of 4 feet and a height of around 4 feet. It has a tendency to be a little lanky, typically having a 1-foot clearance from the ground. It has a medium rate of growth and, in a perfect world, can live for at least 40 years. In both full sun and full shade, this plant thrives. It shouldn’t be allowed to dry out because it prefers to thrive in situations that are generally moist to wet. It is not picky about pH or soil type. It has a strong tolerance for urban pollution and can even flourish in densely populated areas. To safeguard it in exposed areas or colder microclimates in the winter, think about spreading a thick layer of mulch all around the root zone. This particular species is a variation that is not native to North America.
What distinguishes Limelight from Little Lime Hydrangea?
I appreciate you asking, Kay! If planted closer than 4 feet apart, these bushes, which grow between 3 and 5 feet tall and wide, might slightly encroach on one another. Little Lime Hydrangeas fill out and grow very swiftly in a single season. Even though I’ve had my bushes since 2014, I never cease to be amazed! I would really try to stick with 4 feet apart if you want to produce a “hedge” that is defined as a continuous row of flowers. Maybe I might agree to 3.5 feet apart if you were making a hard bargain. I hope this is useful.
Should Little Lime Hydrangeas be deadheaded?
For the shrub, make a hole that is at least twice as broad as the pot it is sold in. However, it shouldn’t be too deep. The hole shouldn’t go any deeper than the plant pot’s soil. After the Little Lime has been planted, the soil around the shrub’s base should be at the same elevation as the surrounding area.
Mulch is essential for Little Lime Dwarf Hydrangeas to thrive. A quality organic mulch preserves soil moisture. Throughout the growing season, this shrub benefits from constant, regular moisture at the roots. Mulch is highly effective at reducing the heat from the sun and the drying effects of cold winds. I mulch my Little Lime shrubs with an organic compost that is listed by OMRI.
Little Lime Hydrangea Pruning
Pruning Little Lime Hydrangeas is not necessary. These compact hydrangeas are bred to grow to a maximum height and width of 3-5 feet. During the first two to three years when the plants establish themselves, pruning is typically not necessary. If planted in a place where they can develop to their full mature size in shrub form, Little Lime shrubs are typically well rounded and may never need pruning for size.
When the young shrubs are well-established, they can be clipped during their dormant state to improve airflow and give them shape. For further information, see the instructions and video below.
So when should Little Lime Hydrangea be pruned? Late winter or early spring are ideal times to prune Little Lime Hydrangeas because the shrub will be dormant. Starting the pruning process early in the growing season promotes the development of stems and flower buds. Little Lime shrubs should be pruned right after the snow has melted. Although it’s still cold enough to be outside in the garden, the bushes are still dormant.
Little Lime Hydrangea blossoms can be deadheaded at any time. Throughout the year, whenever they are noticed, dead, damaged, or diseased stems should also be removed. Despite the fact that this shrub is quite tolerant of out-of-season pruning, hard trimming for shape and size should be done in late winter or early spring.
On recently growing wood, little Lime Hydrangeas bloom. Flowers produce their buds in the spring. Every summer, tiny lime hydrangea blossoms bloom on the spring’s new, bright green stalks. This flowering shrub can be cut in the late winter or early spring without worrying about affecting summer flowers because it blooms on new wood. The stems that will blossom in the summer will grow more quickly as a result of the pre-season pruning.
Additionally, these hydrangeas may tolerate moderate pruning during less-than-ideal seasons of the year. The Little Lime Hydrangea will produce less blooms the next year if it is pruned in the summer. It is not advised to prune these hydrangeas severely in the fall until they have reached dormancy. The opposite of what we want the shrub to accomplish in the fall is stimulated by hard trimming, which encourages growth. After the first frost, remove any dead, damaged, or diseased stems and deadhead the flowers. Save the true pruning for when the hydrangea is dormant.
The ideal time to cut back Little Lime Hydrangeas is in late fall or early spring (while it is dormant for the cold season). Although it’s not strictly required to prune these shrubs, reducing the main stems helps help them grow stronger and produce a fuller shrub with more blooming. Little Lime can be pruned all the way down, but most gardeners choose to shorten the stems before the growing season to promote strong, enduring stems and an abundance of blooms.
Beginning with any branches that are dead, infected, dying, or otherwise damaged, begin pruning your Little Lime Hydrangea. To maintain the branch structure at the base of the plant relatively open for air circulation, I prefer to remove them all the way down to the plant’s base. Next, eliminate any branches that are encroaching on neighboring branches (especially if they are rubbing). You can also cut down any branches that are encroaching on the shrub’s center. Since some primary branches were cut off completely, there should now be fewer of them.
Reduce the height of each surviving stem of the Little Lime Hydrangea by one-third. For example, a 3′ tall Little Lime needs to be reduced to 2′ tall. A taller shrub that is five feet tall can be pruned back to a height of about three to four feet. Now you should be able to see the shrub’s naked permanent foundation (the trimmed main stems that go right to the ground).
Each spring, Little Lime Hydrangea plants produce a significant amount of new growth. Keep in mind that they bloom on newly-grown green wood, so trim the branches back to the main stem to allow the shrub to produce new green flowering shoots. When they are noticed, dead, damaged, or diseased stems should be totally removed (any time during the year).
How To Mulch Little Lime Hydrangea Shrubs
I prefer to use high-quality landscape mulch created from plant debris or my own homemade organic compost as a mulch. Keep in mind that mulch should never actually contact a shrub’s base when adding it. Put absolutely no mulch within six inches of the woody stem base. The plant will quickly cover the area as it grows. Do not be concerned about the unmulched ring at the base. Covering that area in mulch is not worth it!
Harmful microorganisms thrive in the damp, cozy habitat created by mulch contacting the root. The stems have evolved to thrive in dry, free air, not in moist, congested air. Keep the mulch away from the Little Lime Hydrangea’s growing stems. Removing any mulch that creeps up to the plant’s base on a regular basis.
How And When To Fertilize Little Lime Hydrangeas
The ideal time to fertilize Little Lime Hydrangea is in the early spring. Early in the spring, when the plant is emerging from dormancy, treat the surrounding soil with a balanced, slow-release organic fertilizer. In some situations, a smaller feeding around midsummer can be beneficial. The pH of the fertilizer has no impact on the flowers’ color. Here are some top-notch fertilizers for hydrangeas.
