The plant and flower that most closely resembles lilacs is crape myrtle (Lagerstroemia), which is frequently referred to as the Southern lilac. Crape myrtles are woody-growing shrubs or bushes. They have tiny blooms with colors ranging from dark pink to purple to white in cone-shaped flower spikes. The light green leaves of the crape myrtle can grow up to 4 inches long and 2 inches broad. Lilac leaves have a rounder shape.
- Lilacs (Syringa) are deciduous shrubs with clusters of fragrant, cone-shaped flowers that are a mainstay in cold-weather gardens.
- There are various perennials and other cone-shaped flowers that can be mistaken for the lilac flower spike.
Zones 7 to 9, which are too hot for lilacs, are where crape myrtles grow. The best conditions for growing crape myrtles are full sun and moderate watering.
What plants are lilacs related to?
The phrase “summer lilacs” also refers to the butterfly bush (Buddleja species) of the family Scrophulariaceae, which is a genus of plants in the family Rhamnaceae.
What’s the name of those tiny purple flowers?
Bring the vibrant purple tones of the newly blooming plants inside to celebrate spring. Purple flowers will help visitors feel relaxed and at home when they enter your home. Consider growing these flowers in your yard so that you can go outside in the spring and enjoy a picnic among the new blooms.
Verbena (Verbena bonariensis)
Clusters of vibrant purple verbena flowers may be seen blooming. It draws butterflies and is drought tolerant, so it may grow in practically any garden. Verbena has been used for centuries to treat illnesses like gum disease and earaches. The verbena plant represents well-being, imagination, and joy.
Clematis (Clematis)
Clematis are vines that climb and are well-known for their beautiful blossoms. Their name is derived from the Greek word for vine, klematis. Flowers from clematis are poisonous to eat and are only used for decoration. They are a symbol of intelligence and exquisite brilliance. This is a present that is customarily given on your anniversary after eight years of marriage.
Bellflower (Campanula)
Bellflowers are star-shaped flowers with a range of purple colours, often known as campanula. Bellflowers are frequently utilized in gardens as ground flowers and room dividers. Bellflowers stand for affection, steadfastness, and everlasting love.
Small Iris (Iris Reticulata)
The dwarf irises are a tiny yet well-known variety of the iris genus. Their vibrant yellow core and rich purple petals help you identify them. They are used in bouquets and planted in gardens. The dwarf iris represents trust, confidence, and knowledge.
Catmint (Nepeta)
Catmint, also called catnip, is a plant with protracted violet blooming spikes. A common selection for gardens, it draws hummingbirds, butterflies, and bees. When the growing circumstances are difficult, it is frequently used as a substitute for lavender and is coupled with roses. Catmint is a representation of beauty, love, and joy.
Anemone (Anemone nemorosa)
The wind aids in the opening of the wildflower known as “the daughter of the wind.” According to Greek mythology, the anemone was created from Aphrodite’s tears. They stand for protection, luck, and expectation.
Dark Indigo (Baptisia australis)
Being a part of the pea family, wild indigo is a rather simple plant to produce. The stalks can reach a height of 4 feet. For weddings with a lavender color scheme, indigo bouquets are a popular option.
Grass with blue eyes (Sisyrinchium montanum)
Contrary to what its name suggests, blue-eyed grass blooms in little clusters of tiny purple flowers with a bright yellow center. It is a plant that, if left alone, spreads rapidly and is simple to grow.
Hyacinth sp (Dichelostemma capitatum)
The drought-tolerant wild hyacinth is a native of California and can be found thriving in meadows all around the state. It is wonderful for gardens since it draws bees and needs little maintenance. The flower represents perseverance and recreation or sport.
Candytuft (Iberis pruitii)
The Olde English name of the island of CreteCandie inspired the name of this European native plant, candytuft. Cotton candy-like tones in pink and lilac also characterize it. Candytuft stands for apathy. Along with flowers, gardens also include it.
Columbine (Aquilegia)
Dark green leaves and bell-shaped blooms, particularly purple ones, are characteristics of columbine flowers. The purple blossom represents naivete and youth.
Fuchsia (Fuchsia magellanica)
The fuchsia flower has a highly distinctive and exotic appearance. It has layered petals that are two-toned and hang from their bush. They usually grow downward, so hanging baskets are where you’ll usually find them. The plant is a thoughtful present and has romantic symbolism.
Geranium (Geranium)
Geraniums, also called cranesbill, are well-liked garden plants. They are available in a wide range of hues, with purple being one of the most popular. Women’s health, fertility, love, and protection are represented by geraniums.
Lilac (Syringa vulgaris)
On the bush, lilacs produce tiny, purple blossoms that cluster together tightly. It frequently relates to Easter and represents rebirth. Lilacs are frequently found in gardens and floral arrangements because of their sweet aroma.
Rhododendron (Rhododendron)
Daphnoides rhododendron, a member of the rhododendron family, has enormous purple blossoms. They are a springtime flower that blooms with a bell-shaped bloom with a distinctive scent. They are presented as gifts as a symbol of defense.
Scabiosa (Scabiosa)
Scabiosa, sometimes called the pincushion flower, has blue, violet, and purple coloring. The flower got its name because the Romans used it to cure skin conditions like scabies. Despite this, when offered, it is a sign of unadulterated affection.
Wisteria (Wisteria sinensis)
Flowers of the wisteria plant are purple and hang from a vine. It comes from Asia and is a pea family member. The wisteria plant is frequently cultivated from hanging pots or on arbors. It stands for love, beauty, and fertility.
Is Buddleia the same as lilac?
Many butterfly gardens in North America feature lilacs and butterfly bushes, although these two plant species are distinct from one another. Syringa, the genus from which lilacs come, and Buddleja, the genus from which butterfly bushes come.
A hyacinth is it a lilac?
Syringa oblata (Early Lilac) and Syringa vulgaris are vigorous, early-flowering hybrids that produce Syringa x hyacinthiflora (Common Lilac). These wonderful shrubs, which are incredibly hardy, reward us in mid-spring with a profusion of sweetly scented blossoms, around 7–10 days sooner than conventional lilacs. But their appeal extends beyond this. In the fall, its foliage frequently turns colours of crimson, purple, and gold, extending their interest season. Plus, unlike many other lilac kinds, they are very resistant to powdery mildew. Hyacinth lilacs are simple to cultivate, low-maintenance shrubs that will flourish without much care. Every gardener should include these on their list.
- Hyacinth Lilacs are deciduous shrubs that grow 10 to 12 feet high and broad, with an erect habit in youth that becomes fatter with age (300-360 cm). They are ideal as garden specimens or in mixed borders with other shrubs and perennials because to their modest stature.
- Hyacinth Lilacs have pleasantly fragrant flowers that can be single or double and come in a variety of colors. They typically bloom in mid-spring, about 7–10 days earlier than Common Lilacs.
- Their heart-shaped foliage has summer appeal and is extremely resistant to powdery mildew, which can afflict other lilac species.
- Select a location for your lilac that has good soil, drainage, and sun, and take careful care of it. Lilacs are easy to grow in fertile, humus-rich, alkaline to neutral, dry to medium, well-drained soils since they adore full sun. They prefer chalky soils and detest acidic ones. Although it may take some little shade, full sun produces the greatest flowers.
- The heat in the south is not ideal for most hyacinth lilacs. For the buds to grow and bloom the following spring, they require a lengthy period of winter chill. Zones 3 to 7 are advised for planting. However, some Hyacinthiflora lilac cultivars with reduced cold needs, including “Lavender Lady,” “California Rose,” “Excel,” and “Esther Staley,” have been developed for warmer climates.
- Shortly after they stop blooming, lilacs start to set buds for the following year. To sustain flower production the following year, trimming should be done as soon as possible after flowering.
- The common lilac is prone to sucking. Root suckers should be promptly removed to maintain a tidy appearance and stop unwelcome colonial spread.
Why don’t my lilacs smell?
Non-aromatic species or a colder air temperature are the two main causes of lilac bushes that don’t smell. Common lilac, also known as old-fashioned lilac (Syringa vulgaris), often has the most potent and enticing perfume of all lilac species. In actuality, the most aromatic types are typically those that are medium to dark purple.
There are some lilac species, meanwhile, that either have no smell at all or a weak one. For instance, it’s known that some white lilac cultivars are odorless. There are single and double white variations of these.
Additionally, when it’s too cold or wet, many lilacs—including the most fragrant species—don’t smell as good. Your lilac blooms might not smell under these circumstances, which are typical in the spring when lilacs are flowering. However, after it heats up, they’ll start emitting strong, perfume-like scents.
Which lilac 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. As opposed to breeding within a species, most of them are the result of hybridizers crossing two or more species and choosing their strongest offspring. To produce the hybrid group S.prestoniae, Canadian plant breeder Isabella Preston initially crossed S. komarowii ssp. reflexa and S. villosa. Others have since crossed late-flowering species with Preston lilacs. 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.
Lilacs are easy to grow
As simple to raise as vegetables are lilacs. Their requirements are also not that dissimilar. Lilacs grow best in broad sunlight and on healthy garden soil that is neutral to slightly alkaline in pH. In these areas, they will withstand less than perfect conditions, although providing for the needs of the plant will yield better floral results.
Lilacs are typically thought of as cold-climate plants. The majority of lilacs are hardy in USDA Hardiness Zones 3 to 7, therefore when climate is an issue, heat tolerance comes into play. Gardeners in warm climates have reason for optimism. Recent selections developed at Los Angeles’ Descanso Gardens can withstand the heat and the absence of a chilling time. And the University of California, Riverside campus is home to lilac trees. I’ve heard that my old favorite, the early-flowering S.hyacinthiflora ‘Excel,’ is one of the best varieties there.
Bear in mind that lilac flower buds form in the summer before blooming when you are trimming or pruning them. Almost usually, winter pruning leads in fewer blooms the following spring. Lilacs should be pruned as soon as their blooms start to fade for the greatest flowering.
Lilac leaves frequently get powdery mildew on them, especially in humid environments. Since it appears in the late summer and early autumn, after the majority of the growth season, it is typically more of a nuisance than a hazard. Fungicides can be used to control it, however I advise cultivating the plants that are least impacted. The plants that are suggested in this article have only mild to moderate leaf disease symptoms. Site and environment, however, also influence the likelihood of infection.
Another foliar disease called leaf-roll necrosis is thought to be brought on by air pollution and can manifest hundreds of kilometres away from large cities. Similar to mildew, symptoms typically show up in the late summer and early fall. Each leaf coils upward as the leaf margins frequently die and turn dark. The symptoms may be so unpleasant that it may appear as though the plant will perish. Fortunately, at that time, lilacs have finished growing for the most part, and new spring leaves are typically healthy. Again, cultivars respond to injury in varied degrees, so look for ones that maintain their attractiveness throughout the season.
