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.
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.
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 withstand heat?
Syringa x laciniata (Cutleaf Lilac), a deciduous shrub with an elegant, rounded form and loose panicles of fragrant, soft lavender-violet flowers in late spring, is renowned for its heat tolerance and resistance to mildew. They develop into long, gorgeous flowering wands after being born along the willowy, arched branchlets. The lacy, deeply cut, dark green leaves have an airy, finely textured foliage that is just as attractive. It is resistant to mildew, appealing all summer long, and turns yellow-green in the fall. The most heat-tolerant lilac is the cutleaf kind. Perfect for regions with scorching summers and warmer temperatures. A magnificent lilac deserving of a spot in the landscape.
Lilacs can be found in Zone 8?
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.
Do lilacs require a cold climate?
One of the most well-liked scented multiblooming shrubs is the common purple lilac (Syringa vulgaris). In USDA growth zones 3 through 7, this plant flourishes. Lilacs are sturdy plants, so maintaining them is not very difficult. Although they can survive temperatures as low as -40 degrees Fahrenheit (-40 degrees Celsius), they may require some protection from harsh gusts that can harm the flower buds.
Lilacs require chilly winters to help set the blossoms for the next season. There isn’t much upkeep required while the shrub is dormant throughout the colder months. Dehydration brought on by frozen soils and arid winter winds is the biggest issue for lilacs during the winter. The roots are less likely to be harmed by freezing water when the soil is well-draining.
Which month is ideal for lilac planting?
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. However, springtime is a relatively brief season, therefore transplanting at this time is only advised in regions with really harsh winters.
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.
Do lilacs make dogs sick?
Lilacs don’t have any poisonous or irritating substances that could harm people or animals. Even though chewing on lilac stems, leaves, and flowers has no health risks to dogs, it is still a good idea to prevent this from happening. A pet’s digestive tract may become disturbed if they consume too much roughage. Additionally, twigs and leaves might get caught in their throats. Additionally, dogs’ inability to digest large amounts of plant matter can result in nausea or diarrhea. The Persian lilac (Melia azedarach), which is not related to actual lilacs, is deadly to dogs, according to the ASPCA Animal Poison Control Center.
Do lilacs withstand drought?
When the virtually indestructible lilac begins to have some problems, you can be sure that the last few years have seen some severe weather. Over the past several weeks, a number of folks have gotten in touch with the WSU Master Gardener Plant Clinic with inquiries regarding pale leaves and tip dieback.
Lilacs are one of the harder garden shrubs in our environment. They can tolerate drought (to a certain extent) and require little maintenance other than removing the spent flower heads immediately after blooming. They are so hardy, in fact, that they continue to identify the locations of historic homesteads all throughout the area decades after the farmhouses have vanished.
The most frequent problem we get around here is lilac bacterial blight, which causes the leaves and branch tips to turn black. This illness typically manifests during the damp and chilly spring months. But it can also show up when plants are stressed by drought, as they have been for the past two years. In the Inland Northwest, we’ve experienced a few tiny instances of it. Under the correct circumstances, the common lilac (Syringa vulgaris) and its varieties, which we all have in our gardens, can be quite vulnerable to it.
The best way to combat the disease is to keep your plants healthy. By removing dense growth, plants’ air circulation will be improved. In the spring, give the plants a little fertilizer. The plants can become overstimulated by fertilizer applied in excess or at the wrong time of year. In order to lessen drought stress, provide consistent water during the driest months. In order to get rid of disease reservoirs lying in the leaves, clean up old leaves in the fall. Last but not least, if you have already had the disease, you can spray the plants with a copper sulfate solution in the early spring to lessen the likelihood of the ailment.
The Master Gardeners’ observations in the clinic, however, don’t fully fit the description of the bacterial blight on lilacs. The leaves appear chlorotic instead. The leaf is a pale yellow-green with a few brown areas, but the veins are still green. This is uncharacteristic of any other disease and is probably brought on by cultural issues with irrigation, fertilization, and drought stress. Due to the two years of drought, the plant’s ability to adequately absorb water and nutrients was likely diminished, especially during the hot weather we had in August. The plant is now starting to retire the extra leaves since it is unable to support its entire canopy of leaves. The plants will most likely recover, but it will require some time and more watering.
The best method to do this is to isolate your plant watering system from your grass sprinkler system. When the weather is dry, like it is in August and September, you need to water the plants frequently and deeply. Simply place a soaker hose on a timer for three to four hours every two weeks and wind it among the plants.
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.
