Tulippia spp. is the scientific name.
- Plant Type: Perennial, bulb
- 6 to 24 inches
- Sunlight: full sun
- Zones of Hardiness: 4–10
Tulips can fill in and sparkle before your lilacs take over if you’re seeking for a temporary solution. Tulips, which are widely available in a variety of sizes and hues and are simple to grow, bloom in the late spring, just before your lilac tree starts to bloom.
Tulips will receive the light they require to do their dance because your lilac won’t have leafed out when they are about to blossom.
Tulips cannot be trimmed down until all of their leaves have turned totally brown, so consider pairing them with a perennial that can withstand shade and grows big and bushy in the middle of summer. This will conceal the tulip’s unattractive leaves as it stores nutrients for the flowers of the following season.
What plants thrive next to lilacs?
Lilac bushes are also useful as trellises for vines that grow passionflowers, such as maypop. Maypop also produces huge, fringed flowers after the lilac blossoms have faded, as well as gorgeous, tasty fruit.
Where should a lilac bush be planted?
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.
When lilacs are in flower, what do you plant?
- Beans, cucumber, and squash seeds should all be planted at the same time the lilac bush is fully bloomed.
- Beets: Plant beets, along with carrots, crops from the cabbage family, lettuce, and spinach, when the lilac is in its first leaf and the dandelion blooms.
- Broccoli: Plant broccoli when dandelions are in flower and lilacs are just starting to leaf out.
- Plant Brussels sprouts when the dandelions are in flower and the lilacs are just starting to leaf out.
- Cabbage: When lilacs first start to leaf out and dandelion flowers appear, plant cabbage and crops from the cabbage family (broccoli, Brussels sprouts, collards), as well as beets, carrots, lettuce, and spinach.
- When the mock orange is fully bloomed in the fall, plant spring cabbage.
- Carrots: Plant carrots, beets, vegetables in the cabbage family, lettuce, and spinach when the lilac is in its first leaf and the dandelion is in bloom.
- Collards: When lilacs first start to leaf out and dandelions are blooming, plant collards.
- Corn: Sow corn as soon as apple blooms start to wilt and as soon as oak leaves reach the size of a squirrel’s ear.
- Plant cucumber seeds, bean seeds, and squash seeds when the lilacs are fully bloomed and when the blossoms are just beginning to fade.
- Transplanted eggplant: Melons, peppers, irises, and daylilies all begin to flower.
- Plant hardy crops in the spring when the plum and peach trees are in full bloom.
- Plant lettuce, together with spinach, beets, carrots, and crops from the cabbage family, when the lilac is in its first leaf and the dandelions are in flower.
- Melons: Plant melons, as well as eggplant and peppers, as the daylilies and irises begin to blossom.
- Peas: Plant peas once the forsythia and daffodils have finished blooming.
- Peppers, eggplant, and melons should all be transplanted when the daylilies and irises begin to blossom.
- When the first dandelion blooms, sow potatoes.
- Plant spinach, together with beets, vegetables from the cabbage family, carrots, and lettuce, when the lilac is in its first leaf and the dandelion blooms.
- Squash: Plant bean, cucumber, and squash seeds at the height of the lilac bloom and just as it is beginning to fade.
- Warm-season, delicate summer crops: Plant delicate crops as soon as you notice new growth on grapes.
- Tomatoes: Plant tomatoes when the flowering dogwood, lily-of-the-valley, or daylilies begin to blossom.
What occurs if lilac bushes are planted too closely together?
However, if they are planted too closely together, two clusters may eventually form, blending the new and ancient varieties. In particular, if the old clump is already well-established when the new plant is added, older kinds are frequently more vigorous than later, hybridized varieties and may even take over. This can be avoided by placing them six to ten feet apart and managing the size of the clumps.
For your gardening pals, these are wonderful presents. Although unlikely, it’s also conceivable for the two plants to generate enough seed to create a new variety. This can be avoided by cutting the wasted flower clusters, and it also works on perennials like phlox.
Which plants complement hydrangeas well?
Shrubs including boxwood, hollies, yews, mahonia, gardenia, and loropetalum look lovely planted in front of hydrangeas. Early color will come from azalea blossoms. Since the azalea flowers will have faded before your hydrangea blooms, you can choose your preferred blossom color.
During the winter, boxwoods and evergreen azalea species will provide some color. Boxwoods can be shaped or left in their natural form based on your preference for a more formal or natural-looking garden. These may also offer some wintertime protection from high winds.
Is it okay to grow lilacs next to my home?
Lilac roots aren’t thought to be invasive, so planting lilacs close to a building’s foundation poses no risk as long as you give them adequate room. The average root spread for lilac shrubs is 1.5 times that of the shrub’s width. In most cases, keeping objects away from the foundation at least 12 feet (4 meters) will prevent foundation damage.
Are lilacs contagious?
Ballistichory, also known as ballistic dispersion, is a unique way that lilacs disperse their seeds that causes the seeds to fly out in a large arc around the plant. The architecture of the seed pod produces this explosive effect by building stress in the woody fibers as they dry, which causes them to break at a planned weak point and fold back to release the seeds. The lilac can now spread its own seeds without the aid of wind or animals thanks to this technique.
What kind of space does a lilac shrub require?
Lilacs require a lot of space to grow, so that is the first planting rule. They will want a spot that is at least seven to eight feet broad for a hedge and 10 feet wide for a shrub.
Additionally, they require at least six hours of sun each day in order to bloom beautifully. Create an alkaline, well-drained soil. When planting, add a small amount of lime, and then apply it twice a year to keep the shrubs healthy.
Dig a hole for the plant about as deep as the pot or perhaps a little deeper so you can fill the hole with compost. To prepare the lilac roots for spreading out in their new home, remove it from the pot and score the roots. Backfill the hole after placing it in position. Add a little additional compost to the soil’s top layer for an extra boost of nutrients. Thoroughly water. The majority of lilacs are drought-resistant, so once the bush is established, you can let nature handle the watering.
Do any lilacs bloom all summer long?
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.
Specifications
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.
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.
What lilac shrub has the strongest scent?
I had the impression that lilacs were meant for me at times. Working with my grandfather, a nurseryman who specialized in these enthralling beauties, for many hours during my formative years. The tall, pink-flowered “Esther Staley” lilac that grew next to my grandparents’ back door captured my attention the most. Like some people dream of authoring the great American novel, I once fertilized that plant in the hopes of creating a fantastic new lilac. Even though my first attempt at hybridizing failed, I still enjoy breeding lilacs. I also keep an eye on the lilac collection at the Boston-area Arnold Arboretum of Harvard University.
Why are lilacs so alluring? Certainly, the approach of spring is signaled by their wonderful scent. Lilacs are exceptionally simple to grow, and they are distinctive enough to define a color and a fragrance. Additionally, lilacs now come in an astounding range of colors, habits, bloom sizes, shapes, and flowering times. Previously, they were only available in two flavors—purple and white.
There are many modern uses for these traditional plants. Species that are vibrant and fragrant may draw attention. Lilac shrubs can be arranged to create a hedge or screen. Lilacs that grow tall provide shade for a patio. Lilacs can also be underplanted with perennials that will bloom at the same time as them, such as bleeding heart (Dicentra spectabilis) or spring bulbs.
With lilacs, fragrance is the number one priority
Different lilacs have different levels of fragrance. For instance, many white lilacs only have a little aroma. Other lilacs range in flavor from quite sweet to extremely pungent. I am able to perceive pleasant smells, yet my olfactory system seems to swiftly adapt to a fragrance. This makes it challenging to discern between the aromas of various flowers. I still grin when I smell lilacs.
I started a project a few years back to keep track of which lilacs were and weren’t fragrant. I had to find willing sniffers. Now, based on other people’s noses, I can offer fragrant lilacs with assurance.
French hybrids are the best-known lilacs
All lilacs are members of the Syringa genus, which has roughly 20 species and hundreds of widely grown cultivars. Asian species predominate. None of them were born in North America. The common lilac, S. vulgaris, with its heart-shaped leaves and big blooms that bloom around the third week of May here in Boston, is significantly different from many of the species, or wild, lilacs.
The common lilac is an Eastern European native that was brought to Western Europe before 1600 and most likely from there to North America. Named cultivars weren’t created until the 1800s. Since so many of these superior cultivars originated in France around 1900, the word “Even though many common lilac cultivars were developed in other European nations or North America, the term “French Hybrid” is frequently used to refer to all of these varieties.
Other Syringa species have some highly intriguing characteristics outside of the common lilac. Each has a pleasant scent, however some are fairly distinct from S. vulgaris.
S. pubescens, a native of China, is the lilac that is typically regarded as having the strongest scent. It has tiny, purple-tinged white blooms. The aroma is sweet and spicy, extremely unlike the conventional scent “lilac aroma
An lovely native of China and Korea, S. oblata is an early bloomer and blooms approximately two weeks before the common lilac, which it mimics in appearance and aroma. This species is well recognized for being the parent of the S. hyacinthiflora early-flowering hybrid group. The common lilac serves as the other parent. S. oblata and common lilac cultivars have been crossed by breeders to produce some lovely early-flowering, fragrant selections, many of which are disease-resistant. This collection contains some of my favorite cultivars. These include my favorite white lilac, “Sister Justina,” as well as the exquisite lilac-pink varieties “Asessippi” and “Excel.” These three generate a lot of flowers from the top of the plant to the ground, although none of them have particularly large blooms. They have a pleasant scent, and in Boston, the common foliar diseases powdery mildew and leaf-roll necrosis rarely affect them.
Because of its small, intricately cut leaves that resemble ferns, another Chinese species known as S. protolaciniata (which is related to S. laciniata) is called cut-leaf lilac. Unlike the typical lilac, it has inflorescences that appear all the way down the stem from a branch terminal back approximately 18 inches, producing a large number of tiny, light-purple flowers. Some plants can grow up to 8 feet tall and 10 feet across, although they are always incredibly delicate-looking.
Some lilacs are trees
There are tree lilacs that can grow to the size and shape of an apple tree rather of just being large shrubs. They grow beautifully as shade trees, and the second season of interest is provided by their striking bark. My garden is now bordered by a sizable, untrimmed hedge of tree lilacs that was originally planted as a nursery row.
A week to ten days following the late lilacs, which bloom around a month after the early lilacs, come the tree lilacs. They have ivory blooms with a privet-like scent, which is a related relative. Compared to the Chinese tree lilac, the Japanese tree lilac (S. reticulata) often has broader, rounder leaves (S. pekinensis). Both tree lilacs have lovely bark that resembles cherry bark, but the Chinese tree lilac sheds more frequently and comes off in strips. This characteristic makes the cultivar “China Snow” beautiful. The Japanese tree lilac has a cultivar called “Ivory Silk” that is now widely accessible. In addition to being useful in gardens, it seems promising as a little street tree.
A few are short and sweet
I’ve planted a kind of S. patula called “Miss Kim” on either side of my front door. ‘Miss Kim’ is a little shrub that reaches heights of 8 to 9 feet while not being a dwarf. Its leaves acquire a port-wine hue, making it one of the few lilacs with good fall color. It blooms a week or so after the common lilac and has a profusion of deliciously fragrant blooms.
The cultivar commonly referred to as “Dwarf Korean Lilac” is another small lilac. This lilac, S. meyeri ‘Palibin,’ though a dwarf, is a cultivar of a Chinese species rather than a Korean one. Its rarely taller than 4 to 5 foot plants have tiny, circular leaves and tiny blooms. The blooms are a light purple color in the buds, but when they are fully opened, they are white, numerous, and fragrantly pleasant. This variety can be utilized to grow a short hedge.
Late-blooming lilacs have a distinctive look and smell
About a week to ten days after the common lilacs, the late lilacs blossom. Most of them are the result of hybridizers having bred two or more species (as compared to breeding within a species) and selecting the best progeny. To produce the hybrid group S.prestoniae, Canadian plant breeder Isabella Preston initially crossed S. komarowii ssp. reflexa and S. villosa. Others have gone on to cross the Preston lilacs with other late-flowering species. However, these late-flowering lilacs don’t have the typical “lilac” appearance or scent. Sincerely, I believe that these bushes would be more well-known if they were known by a different name. Miss Canada, a true red-pink lilac, and ‘Agnes Smith,’ with white blossoms, are a couple of my favorites.
Lilac flowers range from creamy shades to purples
Although I like purple, I grow lilacs in a variety of hues, including white, blue, purple, magenta, violet, and pink. Even the yellow-lilac S. vulgaris ‘Primrose’ exists. It is a rich, creamy yellow, not the color of dandelions. S.vulgaris ‘Sensation’ is another unusual cultivar; it has purple flowers with white pinstripes encircling each petal. I grew a tall, slender variety of lilac named “Krasavitsa Moskvy,” a Russian introduction of the common lilac, next to my back door. I’m reminded of pink opals when I see its emerging buds, which later bloom into double, white blooms.
Although lilac flowers typically have four petals, many double-flowered cultivars have also been created by hybridizers. Each of these flowers has more than four petals, frequently 12 or more. These can occasionally be put hose-in-hose, which means a four-petal bloom is enclosed by another four-petal flower. Some of the more recent introductions have all of the extra petals radially arranged daisy-style in the same plane.
What qualities should a lilac have? Naturally lovely blossoms. In addition, flowers should be plentiful, fragrant, and come in the color of your choice. And being resistant to sickness is a significant bonus.
My preferred lilacs in the past had huge blossoms. Since then, I’ve come to understand that even the largest lilac flowers can only be seen up close, and that the majority of lilacs are best seen from across a garden or even a street. The quantity of bloom therefore becomes crucial, as well as presentation. You might need to smell your lilacs from a window on the second floor if all of your plant’s blossoms are at the top. Many lilac cultivars grow so tall that single-story homes cannot accommodate them.
