Wisteria is a genus with 810 species of twining, often woody vines in the pea family. Wisteria is also written wistaria (Fabaceae). Wisterias are mostly native to Asia and North America, but they are also commonly cultivated in other parts of the world because of their attractive growth patterns and gorgeous, profusion of blossoms. The plants are invasive species in some areas outside of their natural range where they have escaped cultivation.
The majority of plants can withstand low soils and grow large and quickly. The alternating leaves have up to 19 pinnately complex (feather-shaped) leaflets. The blooms, which are blue, purple, rose, or white, are borne in prodigious, drooping clusters. The deadly seeds are carried by long, slender legumes. The plants are typically grown from cuttings or grafts because they typically take many years to begin blooming.
Where does wisteria typically grow?
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 is advised to buy wisteria plants that are already established or to begin with 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 is it a native of Japan?
wisterias. Japanese wisteria (Wisteria floribunda), which is native to Japan and is the hardiest species in the genus, American wisteria (W. frutescens), which is indigenous to the southeastern United States, and Chinese wisteria (W. sinensis), which is indigenous to China, are all cultivable species.
Wisteria is either Japanese or Chinese.
Wisteria usually grows around historic homes. Chinese wisteria and Japanese wisteria are the two wisteria species that have escaped into the eastern United States. When wisteria becomes established, it can be challenging to get rid of it and can cling to trees and plants in the area for years. In the landscape, they can kill or alter desirable trees.
Vegetative Growth
There are some recognizable vegetative differences between Chinese and Japanese wisterias. Japanese wisteria twines clockwise, whilst Chinese wisteria twines the opposite direction. Japanese wisteria leaves typically have 11 leaflets, but Chinese wisteria leaves can have up to 713 leaflets. Positive identification, however, can be challenging due to some overlap in leaflet traits and the existence of hybrids (Wisteria x formosa Rehd.).
Pinnately complex leaves are typically alternately placed on the stems of wisterias. Leaflets are typically 14 inches long and elliptic to ovate in form. Chinese and Japanese wisterias are high-climbing vines that can grow up to 70 to 80 feet in height, but American wisteria [Wisteriafrutescens (L.) Poir.] only reaches 1525 feet. In Sierra Madre, California, a Chinese wisteria set a record by having a stem length of more than 450 feet. Chinese and Japanese wisterias are typically only constrained by the structure they are supported by. Wisteria stems (vines) tightly wrap around living supports like trees, gradually killing them. The bark on the stems is light brown or tan and relatively smooth. There are produced both lateral and vertical stems. Rooting along the length of the plant, lateral stems normally get more tense with age. Either stem type’s removal can be challenging.
Flowering and Seeds
Before the leaves appear, the Chinese and Japanese wisterias blossom in the spring. Hanging clusters of fragrant flowers with white, violet, or purple petals are produced. A densely hairy (velvety pubescent) legume (seedpod) that has one to four seeds develops from flowers.
Dispersal
Wisteria spreads sexually by seed or vegetatively through stem growth. Since the fruit is deadly, wildlife does not likely spread it frequently. Most likely, infestations in most regions of the United States were made possible by intentional planting as an ornamental for landscape purposes.
Habitat
Fence rows, woodlands, and other landscape features may be affected by wisterias. The surrounding vegetation is replaced by the dense thickets that wisteria develops. These thickets may provide as a habitat for some animals, but they are a formidable barrier to both animal and human activities.
Distribution
Although there are allegedly many Chinese and Japanese wisterias in the eastern United States, the presence of fertile hybrids may jeopardize the current species range. In the United States, American wisteria can be found from Massachusetts to Michigan and south to Florida and Texas. All are grown, notably hybrids of Chinese and Japanese wisterias. The Midsouth is covered in wisteria. American wisteria grows in and around marshes and is typically less aggressive.
Chemical
Since there aren’t many labeled advice for controlling wisteria, more research is required. For suggested chemical applications, see Table 1. These herbicides can be used as foliar, frill, basal bark, cut stump, or soil treatments, among other ways of application. With frill, sometimes known as hack and squirt, an incision in the bark must be made every 2 inches all the way around the woody stem. The herbicide is then sprayed into these apertures. The lower 1824 inches of the entire plant trunk are sprayed with a bark-penetrating adjuvant to apply basal bark treatments. When applied right before bud break, these treatments are most effective on trunks with a diameter of less than 4 inches. After cutting the main stem, applications are performed to the cut stump. To stop the remaining stump from resprouting, spray herbicide on it slightly inside the bark. A nonionic surfactant must also be used in all foliar and basal bark applications at a rate of 3264 ounces per 100 gallons of spray solution. Applications done within two times the dripline of attractive trees may result in harm or death because picloram is absorbed by tree roots. Several desirable trees can be sprayed with clopyralid, making it an excellent option for treating wisteria-draped trees.
Mechanical
Although mechanical controls are an option, they are frequently pricy and labor-intensive. Climbing stems create lateral stems (vines) at their base, which can spread far from the original plant. Climbing vines can encircle trees and shrubs in a tight web that makes removal challenging. Young branches can be pruned by snapping them, but older vines must be clipped.
The US didn’t get wisteria how?

In Hawaii, Chinese wisteria can also be found. Wisteria plants hybridize at a rapid rate.
Distribution maps for the particular species may be dubious due to recent findings in the southeastern states [35,36].

What affects demons does wisteria have?
- The name “Fujikasane,” which means “wrapped in wisteria,” comes from the fact that wisteria is utilized to keep the demons imprisoned on Mount Fujikasane during the Final Selection[3].
- The ranks of the corps members are inscribed on the back of their hands using Wisteria after the Final Selection.
- [4]
- Wisteria may be utilized to make poisons that can immobilize Lower Ranks of the Twelve Kizuki and paralyze common Demons. These poisons have been demonstrated to have the power to dissolve nearly any demon in sufficient concentrations, denying the ability of certain demons to regenerate, as demonstrated by Shinobu Kocho. [5]
- Shinobu was able to alter her own physique by using Wisteria Flower Poison with the aid of Tamayo and Yushiro. As part of her defense against Doma, Shinobu voluntarily changed her own physiology so that every cell of her flesh was covered in wisteria poison[6], transforming her body into a covert human poison capsule that, given enough time, would slowly eat away at the bodies of even the highest Upper Ranks of the Twelve Kizuki. She claimed that her whole size and weight made her equivalent to 37 kilograms of poison, or over 700 times[7] more than what would be required to kill an average demon.
- Shinobu uses wisteria to make a drug that will transform a Demon back into a human.
