When Do Lilacs Bloom In Washington State

The “Excel” cultivar blooms earlier than most lilac kinds, which typically bloom in the middle of spring, around May. To lengthen the flowering season from late winter to late spring, or two nearly continuous flushes of blossoms, combine this early-blooming lilac with other, later-blooming types.

When does the lilac flower bloom?

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.

Does Washington State have lilacs?

The Hulda Klager Lilac Gardens in Woodland, Washington, just a short drive north of Portland, Oregon, welcomes guests from all over the world during Lilac Days. The grounds and house are worth a visit to see the stunning Washington lilac flowers whether you adore the fragrant bush, enjoy Victoriana, or just want to spend some time in the country.

Are lilacs able to thrive in the Pacific Northwest?

I recently went to a wonderful old garden where a lot of the heritage shrubs were fighting so hard. Many of the old lilacs were past their prime and couldn’t be saved, but a few were still going strong. These traditional lilacs were once widespread in dooryards all over the nation, and despite the fact that current hybrids are far more showy, none can compare to the aroma of simple Syringa vulgaris. The so-called French hybrids, among its many progeny, perform particularly well in the Pacific Northwest, where warm winters, cool spring nights, and cloudy days favor bacterial blights, mildews, and other fascinating lilac diseases.

In fact, one reader questions why the tight buds on her double-bloomed lilac are already showing signs of mildew. Unfortunately, we gardeners in the Northwest are better off sticking with single lilacs because doubles often ball up like roses in damp springs. Another reader has expressed disappointment with a lilac that lacks scent; generally, the more recent the hybrid, the more showy the flower, but the weaker the aroma. In April and May, follow your nose to the nursery to find a goodie. My personal favorites are butter yellow Primrose, which has a delicate, sweet aroma, and pure white Vestale, which has smaller blossoms but a powerful perfume. As are Concord-grape purple Agincourt Beauty and sky blue Firmament, as well as deep purple Cavour and wine red Ludwig Spaeth.

Give your lilac a sunny, well-drained location with lots of space for spreading if you want to keep it healthy (up to 10 by 20 feet, though lilacs vary considerably in size). Unless you over-prune them, new plants will have a fantastic start in humus-enriched soil and you’ll enjoy good bloom in only a few seasons. Since lilacs like alkaline soils, add compost and dolomite lime to the planting hole west of the Cascades. The first three years following planting, lilacs may only receive a single dose of a low number (5-5-5) all-purpose food. Lilacs enjoy slow, moderate nourishment from compost. A quart of wood ashes, placed around the dripline, helps create strong roots and promotes free flowering, whereas too much nitrogen will actually reduce bloom.

If you must prune your young lilacs, do so sparingly and allow them to grow into multi-trunked shrubs rather than single-trunked trees. Suckers may encircle older plants, which should be cut off at the base to allow air and light to reach the plant’s interior. Every few years, a few of the oldest stems can be removed, but avoid removing too many at once because the result will be worse than the initial issue. Remove the suckers yearly, particularly in July or August when they are less prone to resprout, if an older plant is overcrowded. Always remove all suckers from below the graft knob if lilacs are grafted.

A young lilac should be pruned once a year after the blossoms have disappeared to keep it in shape. Never shear a lilac with hedge trimmers as this encourages extremely dense foliage, which worsens leaf disease and reduces or completely eliminates the following year’s bloom. Older lilacs may bloom better in different years, but deadheading with care helps balance things out. Cut off the flowering tip of around two-thirds of the spent blooms to do this. Remove the tip and one or two shoots from the remaining third (well-spaced across the entire bush), leaving a Y-shaped pair of leafy buds on the shrub. Lilacs flower the next year because they do so on aged wood.

How often does a lilac tree bloom each year?

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.

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.

Lilacs may they bloom twice a year?

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.

Where in Seattle can I find lilacs?

Due to COVID, it is currently closed, however it will reopen for Lilac Days in 2023. Hulda Klager Lilac Gardens is a restoration endeavor to pay homage to the achievements of renowned lilac entrepreneur Hulda Klager. It has a house from the 1800s as well as adjacent structures and gardens. A national historic site, it is. Each year, Lilac Days honors the location, Hulda’s contributions, and generates money for site upkeep. For the most recent information, see Today in the Gardens.

Which month should lilac bushes be pruned?

All lilacs should generally be clipped right away in the spring after they have finished blooming. Lilacs set their flower buds for the following year immediately after the current year’s flowers have faded, therefore trimming later in the summer or fall will result in the removal of most or all of the blossoms for the following year. The larger common lilacs as well as the shorter or more “shrub like” cultivars are all subject to this timing guideline. While the “when” of lilac trimming is rather simple, the “how” is a little more difficult. For the time being, we’ll refer to lilac pruning as either maintenance pruning or rejuvenation pruning to keep things simple.

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.

Which lilac varieties smell the best?

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.
