Greek syringa, which means “pipe” and refers to the hollow stems, and Latin reticulata, which means “netted or “net-veined,” both refer to the venation of the leaves.
Japan’s northern region is home to the Japanese tree lilac. Usually on limestone, plants can be found growing on cliffs and amid brush. Privet and forsythia are members of the Olive or Oleaceae family. About 30 kinds of trees and plants that are native to Europe and Asia are found in Syringa. The only species that can grow to a size and shape resembling a tree is the Japanese tree lilac.
With spreading branches that create an oblong to rounded crown, the habit is beautiful. Plants can be raised as little trees or tall shrubs. The Japanese tree lilac has a spread of 15 to 25 feet and a height of 20 to 30 feet.
Simple, opposite, whole, ovate leaves range in size from 3 to 6 inches long, half that wide, and have a long, tapering tip. The undersides of the medium to dark green leaves are slightly fuzzy. Autumn brings a light greenish-brown coloration before the deciduous leaves fall.
Creamy-white flowers are produced at the tips of the branches in lengthy panicles that can reach 12 inches in length. The early summer flower clusters are mildly scented and bloom for one to two weeks before losing their allure. Hawk moths are one type of insect that pollinate flowers.
The fruit is a 3/4-inch-long brown, warty, dry capsule. Two winged seeds are inside each capsule. Throughout the winter, the plant still bears the huge clusters of capsules. The fruit is made up of a group of wind-dispersed seed capsules.
A Japanese lilac tree’s rate of growth
The Japanese lilac is a huge shrub or a small tree that blooms in the summer with white flowers. The tree grows between 12 and 18 inches every year.
Are the roots of Japanese lilac trees invasive?
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.

Near the intersection of South Second Street and West Church Street, in Public Parking Lot K’s green space, a crooked and gnarled tree frequently attracts attention from onlookers. The City of Marshalltown is attempting to preserve the arbora Japanese Tree Lilac, even though it is nearing the end of its life.
Madelyn Mowry Irvine adored the tree when she was a little child and lived at 111 West Church Street. She claims that this is one of her earliest memories.
She remarked, “I’m 76 years old and I remember it always being there.
It’s fascinated me ever since.
After the tornado, Irvine contacted professional arborist City Horticulturalist Kristin Titus to ensure the tree wouldn’t be cut down.
The Syringa reticulatas species has a 40–50 year lifespan on average. Although it is indigenous to eastern Asia, you may find numerous of them in Riverside Cemetery, on terraces, and in many of Marshalltown’s city parks.
BY SARA JORDAN-HEINTZ FOR T-R Although the tree has considerable damage, according to licensed arborist Kristin Titus of the City Horticulturalists, the city will work to keep it alive until it needs to be cut down.
When a tree is growing, its leaf canopy and root system should be in balance. However, when a storm comes along and destroys 75% of a tree’s leaf canopy, only 25% of the leaf canopy is left to sustain 100% of the root system. As a result, the tree must find this root equilibrium, according to Titus. “All we can do is hope it keeps blooming.
According to Irvine, a “covenant was established to protect the tree” when her father sold the land to the city. Although Titus admitted she doesn’t know when this arrangement was reached, she did affirm that it does really exist.
When the city purchased the land, they made careful to maintain the tree and built the lot around it, Titus said. “You could probably have put two more parking spaces on that land. There are roughly 20 feet by 20 feet of spaces.
According to Titus, the city would take care of the tree later in the summer to ensure its survival.
Titus remarked, “You can see the limbs that have broken off near the base of the tree. ” Additionally, you can see where concrete was poured (in the trunk), but that is ineffective.
The City of Marshalltown is making an effort to preserve the crooked and twisted Japanese Tree Lilac, which is located on green space in Public Parking Lot K, close to the intersection of S. Second St. and W. Church St.
Titus said that after the tree is cut down in the future, the only method to determine its age will be to count its rings. She stated that the city will probably plant another Japanese Tree Lilac in its place after the tree is removed.
We will wait until it is completely dead before cutting it down, Titus said. “There are trees that appear better than this one right now and they come down within a yearthey just decline so quickly. And there are trees that look like this one and survive another five to ten years.
Japanese lilac trees have a scent.
The Japanese tree lilac blooms a little later and is bigger than the shrub lilacs. Large clusters of its tiny, fragrant, creamy-white blooms are produced.
Do Japanese lilac trees have annual blooms?
Japanese lilacs can reach heights of up to 30 feet (9 meters) and have a spread of 15 to 20 feet. They can be trees or extremely large bushes (4.5-6 m.). The plant’s hollow stems are indicated by the genus name Syringa, which also means pipe. The veiny pattern on the leaves is what gives the plant its name, reticulata. The plant’s distinctive, reddish bark with white markings and naturally beautiful shape make it interesting all year long.
The trees produce clusters of flowers that are a foot long and 10 inches broad. The timing of the blooming is a crucial factor to take into account even though you might be reluctant to plant a flowering tree or shrub that occupies so much area in the garden and only blooms for two weeks. When few other trees and shrubs are in bloom, it blooms when the majority of spring bloomers are finished for the season and summer bloomers are still budding.
Because it doesn’t require substantial trimming to preserve its attractive shape, Japanese lilac trees require little maintenance. It simply requires the odd snip to get rid of broken twigs and stems when grown as a tree. It can require renewal pruning every few years since it is a shrub.
A lilac shrub can it be kept small?
Keep in mind that there are new dwarf types of lilacs available, such as the repeat blooming “Boomerang,” that tend to stay much shorter in height and can easily be kept shorter than 6 feet tall with yearly pruning.
What kind of area 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.
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.
Are disease-resistant Japanese lilac trees available?
Pseudomonas syringae pv. syringae is the bacterium that causes bacterial blight, often known as bacterial canker. The Japanese lilac tree is frequently attacked by this bacterial illness, which enters through wounds or natural pores and creates health issues for the plant. Brown spots with yellow borders appear on the leaves as symptoms. If the spots’ margins overlap, a bigger afflicted region of brown leaf tissue forms, which quickly degrades. The plant may be affected throughout, turning its blooms brown and its buds black. Younger trees are more frequently affected by bacterial blight; older trees are less susceptible. Maintaining a healthy Japanese lilac tree will help it resist disease, which will help you manage this issue. Maintaining clean pruning tools will help to avoid the spread of illness. Affected branches should be cut back to the level of any evident abnormal growths or lesions. When your Japanese lilac starts to develop new plant growth, avoid overhead watering and apply two to three preventive copper fungicide treatments once every week to ten days, suggests the University of Illinois Extension.
- Japanese lilac trees (Syringa reticulata) are low-maintenance plants with a pleasant scent that thrive in a range of environments, including urban regions, suburban areas, and drought.
