Did you know that the National Gardening Bureau has designated 2022 as the “Year of the Lilac”? They have a sweet, eerie aroma and are among the easiest shrubs for your landscaping to maintain that bloom in the spring. Find out how to plant, nurture, and prune your lilacs.
About Lilacs
Syringa vulgaris, or common lilac, is prized for its tenacity, dependability, and scent. Lilacs are so hardy that they can live for more than 100 years and frequently outlive the houses they were planted near.
This tiny, multi-stemmed deciduous shrub (or tree) has approximately ten canes and blooms at eye level. The height of a common lilac can range from 8 to 12 feet, depending on the cultivar. The aromatic flowers attract butterflies and make good cuttings.
There are lilac types that come in white, cream, and even pink and yellow, though the blooms are typically lilac/purple in hue (ranging from very pale to extremely dark). Flowers can be solitary or double in number.
Lilacs bloom in northern states from mid- to late spring for around two weeks. However, there are lilac varieties for early, mid, and late seasons that, when cultivated together, guarantee a consistent bloom for at least six weeks.
Lilacs do best in soil that is fertile, humus-rich, well-drained, and neutral to alkaline (at a pH near 7.0). Add compost to your soil to improve it if it is in bad condition. (Learn more about adding amendments to the soil and getting it ready for planting.) Lilacs don’t enjoy having their feet wet and won’t blossom if they are kept too moist, so make sure the planting area drains well.
Lilacs should be planted in full sun, which is defined as having at least six hours of sunlight each day, for the finest blooms.
How to Plant Lilacs
- If you’re fortunate, a friend may offer you a sucker, or offshoot, of the plant’s root system. The sucker will first appear pitiful, but all you need to do is dig a hole, fill it with soil, and then insert the sucker. water next, and then wait. You’ll be rewarded with enormous, fragrant blossoms in 4 or 5 years.
- Lilacs purchased from nurseries can also be planted easily. If the plant was cultivated in a container, spread its roots out as you plant it; if it was balled or burlapped, gently remove the covering and any rope before doing so. Set the plant 2 to 3 inches deeper than it was while it was growing in the nursery and cover the roots with topsoil. in water Then add more topsoil to the hole to finish it.
- Depending on the kind, place multiple lilac bushes 5 to 15 feet apart.
- Apply a layer of compost under the plant each spring, followed by a layer of mulch to keep moisture in and weeds under control.
- If the weekly rainfall is less than 1 inch, water during the summer.
- If lilacs receive too much fertilizer, they won’t bloom. In the late winter, they can manage a few 10-10-10, but no more.
- Spread some lime and thoroughly composted manure around the base of your lilac bush once it has finished blooming. Remove suckers while you form the shrub by trimming it.
Pruning Lilacs
- Since lilacs blossom on old wood, it’s important to prune in the spring immediately following their bloom. You risk removing the wood if you prune later in the summer. A word of advice: It’s time to prune if your lilac flower clusters are getting smaller!
- After bloom each year, cut away any dead wood. Remove the oldest canes by pruning (down to the ground). Take out the tiny suckers. Reduce weak branches until a robust shoot remains. Reduce tall canes to eye level.
- Remove one-third of the oldest canes (down to the ground) in year one, half of the remaining old wood in year two, and the remainder in year three if your lilac is very old and in poor condition. Cutting the entire plant back to a height of approximately 6 or 8 inches is another option for elderly lilacs. Although it sounds dramatic, lilacs are remarkably resilient. This option’s drawback is that it takes some time for the hair to grow back. The lilac will grow back bursting with blooms, so there will be less work and more reward.
- It is important to understand that extreme trimming causes bloom loss for one to three years. For these reasons, a smart pruning program gives the bushes yearly attention in an effort to avoid making dramatic and severe cuts.
The Syringa vulgaris kind of lilacs is the most widely grown and fragrant:
- Try the double magneta variety “Charles Joly” for an early bloom.
- Lilacs in the middle of the season include “Monge,” a deep reddish purple, and “Firmament,” a delicate blue.
- Miss Canada, a reddish pink, and Donald Wyman, a solitary purple, are two late-season beauties.
Syringa x hyacinthiflora, an early-flowering lilac cultivar, opens 7 to 19 days before those of the common lilac. Hummingbirds and butterflies are attracted to its fragrant blossoms.
The cutleaf lilac, a fragrant pale lavender, is one of the common lilacs that may flourish as far south as Zone 9. Common lilacs appreciate cold weather. The beautiful shrub Syringa patula ‘Miss Kim’ has light lilac-blue flowers that eventually become white.
There are tiny kinds for gardeners who simply don’t have the space for the conventional larger lilacs, particularly those in urban settings. Even in a container on your balcony or patio, they will grow.
- ‘Baby Kim’ has a lovely rounded shape, only grows 2 to 3 feet high (and 3 feet wide), and has purple flowers that draw butterflies. Hardiness from Zones 3 to 8 extended.
- Compact lilac ‘Little Lady’ (Syringa x) has dark pink buds that open to lilac-pink flowers and grows to be 4 to 5 feet tall and wide at maturity. Zones 2 to 7 are tough.
- Syringa vulgaris cultivars “New Age Lavender” and “New Age White” were developed for mildew resistance and are quite compact, growing from 4 to 5 feet tall and wide. Hummingbirds and butterflies are drawn to their fragrant blossoms. Zone 4 hardy.
How and where are lilacs grown?
About 25 species of fragrant and lovely northern spring-flowering shrubs and small trees in the olive family belong to the genus lilac (Syringa) (Oleaceae). Eastern Europe and temperate Asia are the native home of the lilac, and several varieties are extensively grown.
Where do lilacs thrive the most?
When the lilacs begin to blossom, it is a solid indicator that spring has arrived for good. While many people only have a limited knowledge of common lilac (also known as French lilac) shrubs that can reach a height of 15 feet or more, there are now a lot more options available than there were fifty years ago. Some varieties that rebloom enhance the garden’s appeal the entire growing season.
How to Choose Lilacs
The common lilac is what you will most likely find when you go plant shopping. This traditional plant comes in a variety of cultivars and variations, each of which yields fragrant spring flowers in pink, purple, white, or even combinations of those hues. Common lilacs are typically the most fragrant variety of lilac and can grow to be rangy and large.
Rebloomers have arrived in the garden center thanks to recent introductions of hybrids between the common lilac and other shrub-type lilacs. Some of these more recent types are a little less fragrant, but they also tend to be smaller, bloom more frequently throughout the growing season, and have fewer powdery mildew issues.
The tree lilac is another common variety of lilac. It can grow to a height of around 20 feet and blooms with cream-colored flowers in the middle of the summer. Though it doesn’t require much trimming, keep in mind that the tree lilac is a tree, not a shrub.
Where to Plant Lilacs
Lilacs should be planted in full light (at least 6 to 8 hours per day), as too much shadow will prevent them from blooming. Lilacs also prefer moist, well-drained soil that is slightly alkaline.
When to Plant Lilacs
Before the ground freezes in the late fall is the ideal time to plant lilacs. After the earth thaws in the early spring, that is the next ideal period to plant. Lilacs will likely need to be planted as soon as you can locate them at the garden center, which is great; if you choose to do so during a warmer season, they might require additional watering.
How to Prepare the Soil for Planting Lilacs
A soil test should be performed prior to planting since lilacs thrive in slightly alkaline (6.5 to 7.0 pH), moist, well-drained soil that is high in organic matter. Lime must be added to raise the pH if it is below 5.5. It’s time to get the soil ready when you’ve obtained the ideal pH. Improve individual planting holes by mixing Miracle-Gro Garden Soil for Trees & Shrubs in a 50:50 ratio with the natural soil to give lilacs a nutrient-rich start. Iron and phosphorus are also present in this garden soil to promote root development and ward off leaf fading.
Where can you find lilac in the US?
Zones 3 through 7 of the USDA are best for growing common lilacs. Place your lilac plant in a spot that gets at least six hours of direct sunlight every day. Although lilacs can tolerate moderate shade, they probably won’t produce as many of the highly valued blossoms.
To prevent root rot and other diseases, common lilacs need to be planted in loamy, moderately moist, neutral to slightly alkaline soil that has good drainage. Although they can survive the odd drought, they probably would benefit from extra hydration during particularly hot and dry spells.
Additionally, check the soil before adding any fertilizer. You most likely won’t need to fertilize your lilac for a number of years unless the results indicate a demand for a certain nutrient. In fact, too much nitrogen might be bad for the plant.
Suckers are a simple way for lilacs to spread. Simply snip off a fresh stem from the main plant while being careful not to harm its roots if you wish to reproduce the plant. After that, place it somewhere else and give it plenty of water to grow roots in. To keep your lilac in check, merely cut off any suckers if you don’t want it to spread.
Where are lilacs grown?
You are selecting a shrub from our country’s past when you plant a lilac in your garden. For instance, Thomas Jefferson described his lilac planting technique in his Garden Book in 1767, and George Washington stated that he had transplanted existing lilacs in his garden on March 3, 1785. The lilacs at the Governor Wentworth home in Portsmouth, New Hampshire, which are said to have been planted around 1750, may be the oldest still growing ones in North America.
Although lilacs are a part of New England’s horticultural tradition, they are not native to North America, much like the region’s diverse population. Two of the more than 20 species of lilacs are from Europe, and the rest are from Asia. Eastern Europe is where the common lilac (Syringa vulgaris) first appeared. We now refer to these lilacs as “French hybrids” since this species and its hybrids were cultivated and chosen by French nurserymen so regularly that France came to be associated with exquisite lilacs.
Asia is home to the majority of lilac species, including two of the most well-liked varieties for modern landscapes, Syringa patula ‘Miss Kim’ and S. meyeri ‘Palibin. The clean growth habit of “Palibin” fits well in the contemporary garden, while the compact, later flowering “Miss Kim” is known for its potent smell.
Lilacs, which are renowned as plants for colder regions, require a period of cold-initiated hibernation before they begin to bloom. In the north temperate zone, which covers most of North America, Asia, and Europe, hybridizers produce fresh varieties of lilacs. Today, lilac varieties come from all over the world and go by many different names. The International Lilac Society, which oversees global registration, publishes the cultivar epithet (name), which is enclosed in single quotes.
Although the Arnold Arboretum has one of the oldest and largest lilac collections in North America, lilacs have existed on our grounds since the institution’s establishment in 1872. Lilac hedgerows were most likely planted by Benjamin Bussey soon after he purchased the property in 1806. On the east side of what is now known as the Explorers Garden on Bussey Hill, we reconstructed hedgerows using cuttings from the remainder of his lilac trees.
Our Lilac Sunday celebration, which is held on the second Sunday in May, has taken on a life of its own. Lilac Sunday attendance is difficult to predict, however one notable high was reportedly reached in 1941 when 43,000 people are supposed to have attended.

Does England have lilacs?
In the 16th century, lilac was brought from the south-eastern European Alps as a garden shrub, and it has since taken root naturally. Although uncommon, it can occasionally be found in hedgerows and along the edges of woodlands. It blooms in the spring (about May and June) and is frequently used as a decorative plant in gardens because of its beautiful smell and finely colored flower spikes.
