In the spring, wisteria blooms ferociously, producing clusters of lilac-colored flowers on fresh growth that develops from spurs off the main stalks. Check out our Wisteria Growing Guide for more information on wisteria maintenance, including planting and pruning.
About Wisteria
Wisteria is a long-living vining shrub with cascades of blue to purple blossoms that, in the spring and early summer, look stunning hanging from a pergola or archway. However, this vine is known to grow fairly heavy and to grow quickly and aggressively, frequently reaching lengths of more than 30 feet. It’s advised not to put wisteria vines too close to your home since they will squirm their way into any crack or crevice they can find.
Beautifully fragrant wisteria flowers offer a feast for the senses. A brown, bean-like pod remains on the plant during the winter after flowering. There are only blooms on fresh growth.
Note: Be careful when planting wisteria! The wisteria plant contains lectin and wisterin, which are poisonous to people, animals, and even pets. If taken in significant quantities, these poisons can result in anything from nausea and diarrhea to death.
Is Wisteria an Invasive Plant?
The wisteria species Wisteria sinensis and Wisteria floribunda, which are not native to North America, are regarded as invasive in several areas. If you want to add a new wisteria to your garden, we advise choosing one of the native North American varieties, such as American wisteria (Wisteria frutescens) or Kentucky wisteria (Wisteria macrostachya), which are excellent alternatives to the Asian species.
Do you want to know how to distinguish between North American and Asian species?
While North American wisteria is not quite as aggressive in its growing tendencies and has smooth seed pods and fruits in addition to more-or-less cylindrical, bean-shaped seeds, Asian wisteria is an aggressive grower with fuzzy seed pods. Another distinction is that the flowers of American and Kentucky wisterias appear in the late spring after the plant has begun to leaf out, whereas those of Chinese wisteria do not.
When to Plant Wisteria
- Plant during the plant’s dormant season in the spring or fall.
- Wisteria can be grown from seed, although plants from seeds frequently take many years to mature and begin to bloom. It’s advisable to purchase established wisteria plants or start from a cutting.
Where to Plant Wisteria
- Put a plant in full sun. Even while wisteria will grow in some shade, it won’t likely bloom. Sunlight is necessary.
- Wisteria should be grown in fertile, wet, but well-draining soil.
- Wisteria will grow in most soils unless it is in bad condition, in which case you need add compost. Find out more about soil improvements and getting the soil ready for planting.
- Because wisteria grows swiftly and can easily engulf its neighbors, pick a location apart from other plants.
- Additionally, wisteria is renowned for encroaching on and infiltrating surrounding buildings like homes, garages, sheds, and so on. We highly advise against growing wisteria too near your house!
- Wisteria vines need a very strong support, like a metal or wooden trellis or pergola, to climb on. Plan carefully and use substantial materials to construct your structure because mature plants have been known to become so heavy that they destroy their supports.
Wisteria looks gorgeous growing up the side of a house, but use caution when planting it because it is a very strong vine that will get into any crack or gap!
Caring for Wisteria
- Apply a 2-inch layer of mulch and a layer of compost under the plant each spring to keep moisture in and keep weeds at bay.
- Phosphorus is often used by gardeners to promote flowering. In the spring, work a few cups of bone meal into the soil. Then, in the fall, add some rock phosphate. Study up on soil amendments.
- If you get less than an inch of rain each week, water your plants. (To determine how much rain you are receiving, set an empty food can outside and use a measuring stick to gauge the depth of the water.)
- During the summer, try pruning the out-of-control shoots every two weeks for more blooms.
Pruning Wisteria
- In the late winter, prune wisteria. Remove at least half of the growth from the previous year, leaving only a few buds on each stem.
- Also prune in the summer after customary flowering if you prefer a more formal appearance. On fresh growth, spurs from the main shoots of the wisteria develop its blossoms. Trim back every new shoot from this year to a spur, leaving no more than 6 inches of growth. So that there are no free, trailing shoots, the entire plant can be trained, roped in, and otherwise organized throughout this procedure.
- Mature plants that have been cultivated informally require little to no more pruning. However, for a plant that has been formally trained, side branches should be pruned back in the summer to 6 inches, then again in the winter to 3 buds.
- Possess you a fresh wisteria? After planting, aggressively prune the vine. Then, the next year, trim the main stem or stems to a height of 3 feet from the growth of the previous year. After the framework has grown to its full size, midsummer extension growth should be cut back to where it started that season.
Wisteria can it become a tree?
You may teach wisteria to grow up a tree. A wisteria tree can be a great choice for you if you appreciate the way the vines are twisted into a trunk-like shape with the foliage on top. Another name for this is a “standard Wisteria.
As a side note, the term “standard” refers to any plant, usually cultivated as a vine or shrub (not a tree), that has been taught and pruned to develop into a free-standing, single-stemmed tree.
Although you can train your wisteria to resemble a tree, you shouldn’t let the vine climb a real tree. Even though it can be alluring to utilize a tree trunk as a natural support, the wisteria will probably catch up to and eventually harm the tree as it grows bigger, heavier, and higher.
The outcome might be magnificent if you chose to teach your wisteria to grow like a tree. However, in order for your plant to get the desired outcome, you will need to assist it. Wisteria will need a large support stake or some other device to hold it up while it develops and matures because it cannot naturally stand up on its own.
A wisteria tree is what kind of tree?
In the Fabaceae (Leguminosae) family of flowering plants, the genus Wisteria contains eleven species of woody twining vines that are native to China, Japan, Korea, Vietnam, Southern Canada, the Eastern United States, and northern Iran. Later, they were imported to France, Germany, and a number of other European nations. Some species are common houseplants.
The aqueous flowering plant, Hygrophila difformis, belongs to the Acanthaceae family and is more often known as wisteria or “water wisteria.”
How large can wisteria trees grow?
Your final decision when evaluating several wisteria varieties will probably come down to availability and beauty. The Japanese and Chinese wisteria are the most popular varieties you may grow in your yard in the US.
Both feature spectacular bloom clusters, potent perfumes, and a variety of cultivar and color possibilities, which is why gardeners prefer them. Here are additional information about the two types as well as additional species and varieties of wisteria vines.
Japanese Wisteria
This variety, also known as Wisteria floribunda, is capable of producing large flower clusters or conical racemes that can grow up to three feet long. They come in a variety of hues, including deep purple, white, lavender, and blue.
The Japanese wisteria can suffuse your yard with pleasant scents because it is a deciduous vine. It can also give your yard a few soft hues. This plant can also reach heights of between 10 and 30 feet and thrive when grown in full sun with moderately wet soil.
Additionally, it can thrive more successfully in USDA zones 4 to 9. In its tree form, Wisteria floribunda also features green leaves with traces of scarlet. When fall arrives, this has the potential to turn a beautiful yellow.
Additionally, Wisteria floribunda bears racemes with blooms in a range of colors, including purple, red-violet, rose-pink, and white. There are especially magnificent varieties with double blossoms that have powerful yet pleasant scents.
The silvery-gray vines of this wisteria floribunda are particularly easily recognized because in addition to being twisted, they also turn in a clockwise direction. It differs from Chinese wisteria because of this.
Chinese Wisteria
The Wisteria Sinensis botanical name for the Chinese wisteria tree is also well-known. This robust and sturdy climbing perennial is Chinese in origin, as the name suggests. The plant is distinguished by its fragrant, vivid blooms that appear in the spring and summer.
It produces cascading clusters of violet, pink, white, and bluish-purple blooms. They will likely begin to bloom in the early spring and will show up before the leaves. When the plant is in full bloom, the blossoms can reach a length of twelve inches and can almost completely obscure the plant’s silver-gray stalks.
When it comes to its foliage, you’ll see that it resembles copper or bronze leaflets that eventually become green in the summer. Each leaf is oval and elongated, and it has the potential to produce 7–13 leaflets.
It can grow absolutely well in the full sun and reach lengths of between 10 and 25 feet. In soil with medium moisture and moderate fertility, it will also thrive. Expect it to be drought-tolerant as well because it is robust enough.
American Wisteria
This species, which is native to the US and goes by the alternate name Wisteria frutescens, is predicted to do exceptionally well in a number of locations outside of California. The Southeastern regions from Texas to Florida are among them.
The American wisteria is a robust, thin climber that can wind counterclockwise and bear huge racemes of fragrant, eye-catching white or purple blossoms. It features hanging conical clusters with a maximum growth length of 6 inches. Once the foliage appears, it typically blooms from April through May.
The American Wisteria may thrive in USDA zones 5 through 9. Whether you expose it to partial shade or full sun, it is drought-tolerant and has tall, climbing stems that can grow as high as 15 to 40 feet. However, keep in mind that to get the most stunning flowers from this plant, you must always nurture it in moist soil and direct sunlight.
The American variety is less aggressive than the varieties from China and Japan. It is equally as lovely as the aforementioned species, but because it grows more slowly, it won’t take over your garden.
The distinctive pods of the native American wisteria, which are smooth and bean-like, are another way to identify the plant. Such pods are either velvety or fuzzy in the case of the Japanese and Chinese wisteria.
What distinguishes a wisteria tree from a wisteria vine?
Do wisteria vines and trees differ from one another? I’ve been looking for a place to buy a tree because I’ve seen photographs. I’m always being pointed toward the vine, though. Any information would be helpful.
“Wisteria is a deciduous twining climber native to China, Japan, and eastern United States; there is no botanical distinction between a Wisteria vine and a Wisteria tree. British Royal Horticultural Society The training and trimming make a difference. The tree form is a wonderful choice for planting Wisteria in a smaller garden because it has a 30-foot growth potential and may be rather aggressive. These two websites demonstrate how to shape a wisteria vine into either the traditional or tree form. There is also a link to instructions on growing wisteria.
What stands for a wisteria tree?
In the majority of cultures where the plants are native, wisteria is a symbol of romance. The Wister flower, in particular in Korea, symbolizes affection that endures after death. Wisteria is seen by the Japanese as a sign of prosperity, longevity, and good fortune.
