When Do Lilacs Bloom In Tennessee

Is there anything else that has a scent as delightful as a springtime lilac shrub in full bloom? Aside from smell, their blossoms are stunning as well! Although there are several varieties of lilacs that will thrive in the Middle Tennessee region, they won’t endure the hot summers and mild winters in the southern part of our state. Here are some wonderful pictures of ours at Riverbend in full bloom, along with some advice on how to take care of these lovely plants! Read on!

Lilacs thrive in our region in full sun with a little midday shade. They prefer somewhat acidic, well-drained soil.

Lilacs prefer soil that has a pH between 6.5 and 7.0, which is slightly acidic to slightly alkaline, for the best bloom.

You may get a straightforward soil test from your neighborhood home improvement store to determine the pH level of your soil!

You can enhance pH by adding ground limestone to the soil surrounding your lilac if it turns out that you need to alter your soil to make it more acidic or alkaline. You might apply aluminum sulfate to your soil to reduce pH.

In light of your pH, ask us or a gardening expert how much to use! In order to prepare for the spring blooming season, this modification is best done in the fall.

These large-growing, deciduous shrubs—the majority of which reach maturity heights of 12–16 inches—make striking individual statements in gardens.

In addition to the variations you can see here, Riverbend also has ‘Betsy Ross’ and ‘Bloomerang,’ a tiny, dark purple variety that only grows to be 4-5 tall.

So there you have it—a few lilac kinds that may be grown in your backyard and do well in our warmer environment.

Which month does the lilac flower?

A lilac in full bloom is a magnificent sight, and it smells great. Lilacs are one of the best flowering shrubs and a staple of the spring landscape in northern and colder climes. These hardy shrubs have been developed to satisfy the requirements of all gardens since they are simple to cultivate, strong as nails, resistant to deer, and largely free of main pests.

  • Lilacs can bring color and scent from April through June, depending on where you live and the types you pick. It is possible to have two months of spring blossoms by making wise plant choices, especially if the weather is chilly. However, a warm spring will cause flowers to blossom earlier than usual, cutting the blooming season by a few weeks.
  • Choose Syringa x hyacinthiflora (Hyacinth Syringa) for the earliest blooms; they begin blooming in mid-spring, about 7–10 days earlier than Syringa vulgaris (Common Lilac).
  • The longest flowering species is the common lilac, which can last up to a month depending on area and cultivar. It often blooms in late spring and has the biggest, most fragrant flowers.
  • With varieties like Littleleaf Lilac (Syringa microphylla) and Japanese Tree Lilac, you may extend the lilac season into the summer (Syringa reticulata).
  • Choose a reblooming lilac if your space is constrained and you can’t enjoy several lilac kinds. These lilac bushes do not only bloom for a brief period in the spring. They extend their stay by repeatedly blooming throughout the summer and the fall, adding beautiful color and fragrance to the garden.
  • Lilac trees grow best in the fall, just after the leaves have fallen and before the ground freezes. Lilacs can be planted in the spring before the buds open. But because fresh roots have a head start in April before the shrub starts to leaf out, lilacs planted in the fall typically have a higher chance of surviving.

How often does a lilac flower bloom each year?

The late lilac is the leading contender for a long-lasting lilac that will bloom profusely throughout the warmer months of the year (Syringa villosa). As its name suggests, it blooms later than other types and produces fragrant white, pink, rosy lilac, violet, and even crimson blossoms. This lilac bush only has one summer bloom and enjoys direct sunlight.

Consider a reblooming lilac for your garden if you want consistent flowers. Lilacs that rebloom will first bloom in the spring, then rest until summertime when they will blossom once more. After their spring rest, certain types, such as the Bloomerang dark purple, will continue to bloom until the fall. Look for the Josee reblooming lilac (Syringa Josee), which intermittently flowers throughout the summer and into the fall, if you live in a warmer climate.

Are lilacs a summer or spring flower?

Lilacs are beloved for a variety of factors, such as their lovely blossoms that draw butterflies, fragrant scent, and simplicity of upkeep in the garden. Why settle for just one chance to enjoy lilac blooms when you can grow a kind that blooms again later in the season? Most lilacs only flower once a year, which is typically in the spring. A hybrid lilac cultivar called Bloomerang (Syringa ‘Penda’), which was released in 2009, begins to bloom in the spring, takes a brief pause, and then resumes in the summer and into the fall. It has gorgeous pale purple flowers that get a little bit darker during the second bloom in the summer and fall. Additionally, Bloomerang maintains a more compact size at a height and width of around four to five feet, unlike older lilacs that can develop into enormous, gangling bushes that reach a height of 10 feet or more.

Do lilac trees have two blooming seasons?

Compared to other lilac trees, bloomerang lilac trees are more compact, reaching a short height of 4-6 feet tall and a spread of 4-6 feet, giving them a pleasing, rounded appearance. Their long, arched branches bear their veined leaves, which are bright green for the majority of the year until turning yellow in the fall.

The characteristic 4-petaled, 4-6 inch deep lilac-purple blooms on bloomerang lilac trees appear starting in May, cease blooming in June, and then return in July through the first frost of the year.


With tall, arched branches, a compact and rounded shape, and rich green foliage that turn golden in the fall. Four spread petals, 4-6 inch, lilac-purple flowers that bloom in the spring and later in the summer.

Why hasn’t my lilac bush bloomed?

A. There are a number of potential causes for your lilac’s failure to blossom. Lack of sufficient sunlight is the main culprit. Lilacs (Syringa) should be planted in an area with at least six hours of direct, bright sunlight per day. They can withstand a wide range of moisture levels as long as they are grown in soil with good drainage.

If your lilac is clipped at the wrong time of year, it might not blossom for another reason. Lilacs bloom in the spring on the growth from the previous year, and soon after, they begin to form the buds for the following year. Within a few weeks of the plant blooming, pruning must be done simultaneously with the removal of the wasted flowers in order to prevent the removal of the buds for the following year. A late freeze can harm flower buds on types that bloom early.

Lilacs have a tendency to mature into overgrown, leggy shrubs with minimal foliage at the bottom. When this occurs, it might be required to prune them to within 12 inches of the ground in order to completely rejuvenate them. When the shrubs are dormant in late winter, this should be done. Lilacs benefit from this repair, although their blooming cycle will be hampered for at least one season. Lilacs can receive a rejuvenation pruning over a two-year period to stop the interruption of bloom cycles. Half of the shrub’s stems should be hard pruned the first year, and the remaining stems the following year.

Lilacs do not consume a lot of food. Excessive fertilization, particularly nitrogen fertilizer, can frequently promote luxuriant vegetative growth at the expense of flower development. A lilac’s failure to bloom could potentially be due to its proximity to turf that receives frequent fertilization.

What distinguishes a lilac bush from a lilac tree?

Lilac bushes (also known as shrubs) are characterized by their numerous woody stems that emerge from the plant’s base. In contrast, the trunk of the majority of lilac trees is the only woody stem. However, your neighborhood garden center might also sell shrub lilacs that have been grafted onto a single stem to give them the appearance of miniature trees.

The choice between a lilac tree and a lilac bush is typically determined by the amount of space available. Lilac bushes come in a range of sizes and can be placed in more compact areas of a garden. A lilac tree requires space to reach heights of 20 feet and widths of 15 feet. Both require sunlight to bloom well.

Should lilacs be Deadheaded?

Dwarf lilacs that resemble ordinary lilacs include the “Palibin” Meyer lilac (Syringa meyeri “Palibin”) and the “Miss Kim” Manchurian lilac (Syringa pubescens ssp. patula “Miss Kim”). However, they hardly ever need pruning for maintenance, though you can do it sometimes for shape. They can also profit from deadheading, just like other lilac kinds.

The act of manually removing withered blossoms from a plant is known as deadheading. This encourages some plants to continue blooming. But only during the first several years of growth does deadheading seem to make lilacs bloom more effectively.

Within two to five years, young lilac plants should start blooming. Deadheading the spent blooms when the plants are young encourages the plant to focus its energy on developing new buds. It won’t require this stimulation once the plant has grown older, and you’ll probably have so many flowers that the task would take too long.

Your lilac will blossom beautifully some years, and less so other years, just like with any plant. Blooms frequently rely on the climate. You will be rewarded with an abundance of blossoms the next year if you have a beautiful summer during which strong new growth emerges. Less flowers will bloom in a summer with harsh weather. Therefore, if your lilac’s color changes from one year to the next, don’t get alarmed. The blossoms will come as long as the plant is strong and you continue with maintenance pruning.

Do lilacs regrow every season?

The majority of lilac shrubs bloom each year, but poor trimming can prevent flowers from appearing the following year. When it comes to properly pruning lilac shrubs, time is crucial because the buds for the bush’s blooms the following year are formed quickly after the bush has completed blooming.

After the new buds have formed, pruning your lilacs may result in few or no blooms the following season. It can take several years before you see any flowers if you prune your lilac bushes too aggressively. The best course of action is to deadhead faded flowers and, if required, prune your lilacs immediately following the blooming period.

How are lilac plants kept in bloom?

The common lilac, Syringa vulgaris, is a big bush that bears fragrant flowers in purple and white hues. Early June is normally when lilac shrubs have their brief blooming season. Pruning lilacs is one of the greatest ways to keep them blooming year after year, even though they are pretty sturdy plants on their own and will produce more blooms every year. By removing the old wood from a lilac bush, fresh blossoms can appear in the spring.

Wait till the final season’s blossoms have passed away and fallen off. As soon as the blooms of the current season fade, a lilac produces new shoots for the following spring bloom. This is why it’s crucial to prune as soon as the blooms fade.

Cut the terminal shoots and branches of the lilac bush back to the lateral bud using your pruning shears. The branches should be pruned back until they are 1/4 inch from a bud that is facing the direction in which you want the new shoots to emerge. This procedure guarantees your lilac will bloom the following year in addition to giving the bush the shape you want.

How do lilacs appear in the summer?

The summer lilac is a big, quickly expanding shrub recognized for its protracted clusters of long cone-shaped flowers. There are numerous cultivated kinds with a variety of blossom hues, including lilac, crimson, and white. Because the tiny flowers frequently feature orange eyes, the plant is also known as the orange-eye butterfly bush. Although the summer lilac is a well-liked selection for butterfly gardens, it has a propensity to spread aggressively. Buddleja davidii is its scientific name.

The summer lilac is a tall shrub that can reach heights of 12 feet (3.7 m) and spreads out to a diameter of up to 8 feet (2.4 m). Long panicles, or branching flower clusters, which can reach a length of 12 inches (30 cm) or more, are how the blooms grow. The scent of the tiny blossoms is prized. The shrub blooms throughout the summer and frequently into the fall. Its 2 to 3 inch (5 to 8 cm) long, pointed, thin leaves are often gray or green in hue.

Since B. davidii is a deciduous shrub, its leaves fall off every year. Because of this, pruning is rarely necessary until the plant has grown excessively large throughout the growth season. It is advised to eliminate dead growth in the early spring after the winter. If they haven’t been entirely destroyed, plants can be shaped in the spring for decorative purposes or to control their growth; neither of these will have an impact on the summer flowering of the plant. The plant is hardy across the majority of the United States, with the exception of the hottest or coldest regions.

Lilac bushes’ lifespan is how long?

Lilacs are renowned for their longevity and hardiness.

Numerous lilac shrubs reach ages of greater than 100. They frequently outlive the residence of the gardener who planted them due to their extended lifespan. As a result, if you’re driving along a country road and come across a few what appear to be random lilac bushes, it was probably a farm or house a century ago.

Try growing lilacs in your garden if you haven’t already. They not only return every year, but they also put on a display for the senses with vibrant blossoms and enticing scents. Lilacs have a lot to offer, and learning about their history demonstrates just how unique these plants are.
