Lilacs, which are prized for their lovely scent, are a staple of the springtime landscape in northern and colder countries. They are among the most efficient blooming shrubs because they are simple to grow, hardy as nails, resistant to deer, and largely devoid of serious pests.
Sadly, not all lilacs thrive in the southern heat. For the buds to grow and bloom the following spring, they frequently require a lengthy period of winter chill. However, a few lilac cultivars and variations do well in the Lower South.
Follow these simple guidelines to grow lilac bushes and receive the best flowers: find a location with adequate drainage, good soil, decent sun, and provide good care.
- Lilacs are easy to grow in fertile, humus-rich, alkaline to neutral, dry to medium, well-drained soils since they adore full sun. Although it may take some little shade, full sun produces the greatest flowers.
- Also requiring space is lilac. It’s critical to have good air circulation to minimize powdery mildew problems.
- The amount of blooms produced the following year will increase if withered blossoms are promptly removed before they set seed.
- To sustain flower production the following year, trimming should be done as soon as possible after flowering. Shortly after they stop blooming, lilacs start to set buds for the following year.
Here is a collection of lovely lilac cultivars and variations appropriate for the Lower South.
Zones:
The majority of lilac types can withstand cold temperatures in zones 3 to 8, although others, like Scentara Double Blue, can (S. hyacinthiflora). There are some cultivars that don’t require a winter chill, like as “Lavender Lady” (S. vulgaris), which is heat tolerant to zone 9. The majority of others do need a wintertime period of cold and dormancy.
Height/Spread:
The common lilac, Syringa vulgaris, reaches heights of 12 to 15 feet and widths of 10 to 12 feet. The majority of dwarf types are smaller and reach maturity at 4 to 6 feet tall and 3 to 7 feet broad. Syringa reticulata, often known as the Japanese tree lilac, grows up to 30 feet tall.
Bloom Time:
The majority bloom in late May, however there are new re-blooming kinds, such the Bloomerang series, as well as early spring, mid-spring, and late-season blooming variants.
Color:
The common lilac (Syringa vulgaris) has gray to gray-brown bark, purple blooms, and dark gray-green to blue-green foliage (with no fall color change). But there are actually seven recognized hues for lilac flowers: white, violet, blue, lavender, pink, magenta, and purple, with several variations of each hue.
Other:
True lilacs, such as the California, mountain, and wild lilacs, are truly members of the genus Ceanothus. Butterfly bushes are frequently referred to as summer lilacs, especially sterile and non-invasive varieties.
Lilacs can be found in Zone 9?
The traditional variety of lilac, common lilacs (Syringa vulgaris), have the largest flowers, the greatest smell, and the longest-lasting blooms. They only flourish in zones 5 through 7 and often need cold winter months. For zone 9, they are inappropriate as lilacs.
Lilacs can they grow in zone 9? a few can. Lilac shrubs that flourish in U.S. Department of Agriculture plant hardiness zones 8 and 9 can be found with little to no effort.
Zone 9 Lilac Varieties
If you want to cultivate lilacs in zone 9, consider the newer cultivars rather than the traditional varieties. A few have been bred to thrive in hotter climates.
Among the most widely used options is Blue Skies (Syringa vulgaris) “Blue Skies), which has flowers that have a strong scent. Syringa x hyacinthiflora, sometimes known as the Excel lilac “The hybrid Excel) blooms up to 10 days earlier than other kinds. It has a maximum height of 12 feet (3.6 m). Cutleaf lilacs (Syringa laciniata), another lovely species, might also thrive in zone 9.
Lavender Lady (Syringa vulgaris) is an additional potential “Lavender Lady), a hybrid produced by Descanso. It was created for the climate zone 9 in Southern California. A little lavender tree called Lavender Lady can grow up to 12 feet (3.6 m) tall and half that broad.
In addition, Descanso created White Angel (Syringa vulgaris) “Another alternative for zone 9 is White Angel. The lilac blossoms on this shrub are a stunning creamy white.
Additionally, keep a watch out for Bloomerang, a brand-new lilac from Proven Winners. It thrives in zone 9 and blooms profusely in the spring with light or dark purple flowers.
Where shouldn’t lilac bushes be planted?
Avoid planting lilacs in areas that will receive more than a half-worth day’s of shade because they thrive in full sun. Make sure to give them room to expand when you plant them. To find out the mature plant’s height and spread, read the label on the plant.
Lilacs require sufficient drainage to thrive. The soil should have just enough moisture to support the root system while still allowing for free drainage after heavy rains.
Dig a hole that is about 8 inches in diameter and 12 inches deep to test the drainage before planting. Add water to the hole. Choose a different location if the water hasn’t drained after an hour.
Lilacs can they grow in zone 8a?
Lilac kinds are quite varied and range from little shrubs that only grow to a height of four to eight feet, up to trees that can reach a height of thirty feet. Because lilac plants are native to the chilly, lower highlands of Asia, the majority of lilac types are hardy in Growing Zones 2 through 7. But nowadays, even people who live in warmer climes can grow lilacs because some types will bloom in Growing Zones 8 and 9.
Can lilacs be grown in Zone 7?
Lilacs are the ideal cold-weather shrubs, necessitating over 2,000 chill hours below 45°F for them to bloom.
I never would have thought to compare it to an olive tree because of its love of cold weather.
However, perennial, deciduous lilacs belong to the Oleaceae branch of the olive family. Although most lilacs grow in Zones 3–7, some can survive in Zone 2. Other cultivars that were developed expressly for warmer climates thrive in Zones 8 and 9—and in some areas of Zone 10 as well.
The genus Syringa consists of twelve species, and if you’re just getting started, our guide to growing lilacs will teach you everything you need to know about how to grow each one in your yard.
The genus was given its name by Swedish scientist Carl Linnaeus in 1753. The Greek word “syrinx,” which meaning pipe or tube, is where the word “syringa” originates. It alludes to Syrinx, a mythical nymph who transformed into hollow reeds to flee the lusty advances of the god Pan.
Syrinx provided us with terminology for hollow objects like syringes and the sturdy yet hollow branches of lilac plants.
Lilacs are distinguished by their panicles of purple, pink, or white flowers as well as their heart-shaped, deep green foliage on some cultivars. The common lilac, S. vulgaris, is the species that is grown most frequently in the United States.
Numerous of the lilacs listed below are S. vulgaris varieties and are referred to as “French hybrids” or “French lilacs.” They are not interbred with other species because they are intraspecific crosses.
Thanks to Victor Lemoine and his wife Marie’s work in the 1870s, many of these originated in France. Between 1876 and 1953, the family introduced more than 200 cultivars thanks to their son and grandson, who carried on the family’s lilac breeding tradition.
Despite the fact that many were and still are grown in the United States and other European nations, the term “French hybrid” has persisted.
Some varieties are double-flowered for an extra-full, lush look with as many as 12 petals on a single flower, whereas French hybrids may be single flowered with four petals on each bloom.
The majority of French hybrids mature at a height of four to twenty feet. While some grow compactly and uprightly, others have a propensity to spread.
Reblooming refers to the ability of some plants to flower in the spring and then display new color in the late summer.
Additionally, Victor Lemoine crossed S. vulgaris with the Chinese lilac, S. oblata, to create what are known as S. x hyacinthiflora lilacs. These early-blooming variants have delicate hyacinth-like flowers.
Between 1912 and 1946, Isabella Preston, a well-known Canadian plant breeder, created 82 different hybrid lilac varieties. These are also known as S. x prestoniae, or Preston lilacs.
Other typical species are:
- S. reticulata, often known as the Japanese tree lilac, is a fragrant tree that can reach heights of up to 30 feet and a spread of 20 feet.
- S. meyeri, also known as S. pubescens, is a type of Korean lilac that only reaches a height of seven feet and a spread of five feet.
- The fragrant Persian S. persica is a four to eight foot tall plant with a spread of five to ten feet and is indigenous to Iran.
- S. emodi, often known as Himalayan lilac, has an upright growth habit, can grow up to 16 feet tall with a 13-foot spread, and has an unpleasant odor.
They are all exquisite in their own right, and the majority of them emit some of the most seductive aromas.
Is it simple to grow lilacs?
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.
