Wisteria is a genus of flowering plants in the legume family, Fabaceae (Leguminosae). The genus includes four species of woody twining vines that are native to China , Japan , Korea , Vietnam , southern Canada , the Eastern United States , and north of Iran . They were later introduced to France, Germany and various other countries in Europe. Some species are popular ornamental plants. The genus name is also used as the English name, and may then be spelt 'wistaria'. In some countries in Western and Central Europe, Wisteria is also known by a variant spelling of the genus in which species were formerly placed, Glycine . Examples include the French glycines , the German Glyzinie , and the Polish glicynia .
23-534: Sierra Madre Wisteria or The Wistaria Vine is a flowering Wisteria vine shown at the annual Wistaria Festival in Sierra Madre, California . The Wistaria Vine in 1990 was declared by the Guinness Book of World Records to be the largest blossoming plant in the world. The Wistaria vine is named after physician Caspar Wistar (1761–1818) by botanist Thomas Nuttall (1786–1859). The general name for
46-408: A few years, as in W. macrostachya (Kentucky wisteria), or nearly twenty, as in W. sinensis . Maturation can be forced by physically abusing the main trunk , root pruning, or drought stress. Wisteria can grow into a mound when unsupported, but is at its best when allowed to clamber up a tree, pergola , wall, or other supporting structure. W. floribunda (Japanese wisteria) with longer racemes
69-696: Is an aid in identifying the two most common species of wisteria. They can climb as high as 20 m (66 ft) above the ground and spread out 10 m (33 ft) laterally. The world's largest known wisteria is the Sierra Madre Wisteria in Sierra Madre, California , measuring more than 1 acre (0.40 ha) in size and weighing 250 tons. Planted in 1894, it is of the 'Chinese lavender' variety. The leaves are alternate, 15 to 35 cm long, pinnate , with 9 to 19 leaflets. The flowers have drooping racemes that vary in length from species to species. W. frutescens (American wisteria) has
92-486: Is debate over whether the concentration outside of the seeds is sufficient to cause poisoning. Wisteria seeds have caused poisoning in children and pets of many countries, producing mild to severe gastroenteritis and other effects. In North America, W. floribunda (Japanese wisteria) and W. sinensis (Chinese wisteria) are far more popular than other species for their abundance of flowers, clusters of large flowers, variety of flower colors, and fragrance. W. sinensis
115-560: Is in spring (just before or as the leaves open) in some Asian species, and in mid to late summer in the American species. The genus Wisteria was established by Thomas Nuttall in 1818. He based the genus on Wisteria frutescens , previously included in the genus Glycine . Nuttall stated that he named the genus in memory of the American physician and anatomist Caspar Wistar (1761–1818). Both men were living in Philadelphia at
138-500: Is now over a meter in diameter. The lavender flowers have a sweet fragrance. Mrs. Brugman sold the home and the vine to Henry and Estelle Fennell in 1906. The Fennells promoted the vine's growth, building arbors and trellises to keep it off the ground. The vine is on the alluvial plain of the San Gabriel Mountains , with a good water source and drainage. The Fennells let the vine grow onto the house. From 1904 to 1950,
161-518: Is the best choice to grow along a pergola. W. sinensis (Chinese wisteria) with shorter racemes is the best choice for growing along a wall. Whatever the case, the support must be very sturdy, because mature wisteria can become immensely strong with heavy wrist-thick trunks and stems . These can collapse latticework, crush thin wooden posts, and even strangle large trees. Wisteria allowed to grow on houses can cause damage to gutters, downspouts, and similar structures. Wisteria flowers develop in buds near
184-548: The Fuji Musume (or 'The Wisteria Maiden'), is the sole extant dance of a series of five personifying dances in which a maiden becomes the embodiment of the spirit of wisteria. In the West, both in building materials such as tile, as well as stained glass, wisterias have been used both in realism and stylistically in artistic works and industrial design.

207-578: The Pacific Electric 's Sierra Madre Line street cars bought visitors from around greater Los Angeles to Wistaria Festival. The weight of the vine later destroyed the house, collapsing the roof. A new house was built north of the vine. In 1936, the Fennells sold the house and vine to Carrie Ida Lawless. Lawless built new arbors and trellises to keep the vine off the ground and the house. Lawless died in 1942, and her nephew Bruce McGill inherited
230-593: The Chinese wisteria ( Wisteria sinensis ). The Wistaria Vine currently spans two backyards in Sierra Madre. In addition to the annual tour of The Wistaria Vine, the city hosts an artisan's arts and craft festival. Wistaria Festival also has live music at Sierra Madre Memorial Park , with food trucks. The vine is in bloom for March to mid-April. The Wistaria is on the City of Sierra Madre's Flag designed in 2005 with
253-659: The Portuguese botanist and geologist José Francisco Corrêa da Serra , who lived in Philadelphia beginning in 1812, four years before his appointment as ambassador of Portugal to the United States, and a friend of Wistar, proposed the name "Wistaria" in his obituary of Wistar. As the spelling is apparently deliberate, there is no justification for changing the genus name under the International Code of Nomenclature for algae, fungi, and plants . The genus

Wisteria The aquatic flowering plant commonly called wisteria or 'water wisteria' is Hygrophila difformis , in the family Acanthaceae . Wisterias climb by twining their stems around any available support. W. floribunda (Japanese wisteria) twines clockwise when viewed from above, while W. sinensis (Chinese wisteria) twines counterclockwise. This
299-552: The World Online accepted four species: Wisteria species are used as food by the larvae of some Lepidoptera species including the brown-tail moth . The seeds are produced in pods similar to those of Laburnum , and, like the seeds of that genus, are poisonous . All parts of the plant contain a saponin called wisterin, which is toxic if ingested, and may cause dizziness , confusion, speech problems, nausea, vomiting , stomach pains, diarrhea and collapse. There
322-457: The base of the previous year's growth, so pruning back side shoots to the basal few buds in early spring can enhance the visibility of the flowers. If it is desired to control the size of the plant, the side shoots can be shortened to between 20 and 40 cm long in midsummer, and back to 10 to 20 centimetres (3.9 to 7.9 in) in the fall. Once the plant is a few years old, a relatively compact, free-flowering form can be achieved by pruning off

Wisteria is one of the five most commonly used motifs in the mon , and there are more than 150 types of wisteria mon . Because of its longevity and fertility, wisteria was considered an auspicious plant and was favored as a mon , and was adopted and popularized by the Fujiwara clan as their mon . One popular dance in kabuki known as
368-741: The house and vine. McGill worked with the Sierra Madre Garden Club in care of the vine. The original lot was subdivided in 1961, so the vine is now on two adjoining properties. Due to the vine's status, the vine is now maintained by experts from universities and local horticulturists. The Sierra Madre Wisteria is one of the Seven Horticultural Wonders of the World . Sierra Madre is known for its annual Wistaria Festival normally held in March. Wistaria Festival showcases
391-1007: The longest racemes of wisteria species, is decorative and has given rise to many cultivars that have won the prestigious Award of Garden Merit . Wisteria, especially W. sinensis (Chinese wisteria), is very hardy and fast-growing. It can grow in fairly poor-quality soils, but prefers fertile, moist, well-drained soil. It thrives in full sun. It can be propagated via hardwood cutting, softwood cuttings, or seed. However, specimens grown from seed can take decades to bloom; for this reason, gardeners usually grow plants that have been started from rooted cuttings or grafted cultivars known to flower well. Another reason for failure to bloom can be excessive fertilizer (particularly nitrogen ). Wisteria has nitrogen fixing capability (provided by Rhizobia bacteria in root nodules), and thus mature plants may benefit from added potassium and phosphate , but not nitrogen. Finally, wisteria can be reluctant to bloom before it has reached maturity. Maturation may require only
414-807: The new tendrils three times during the growing season in the summer months. The flowers of some varieties are edible, and can even be used to make wine. Others are said to be toxic. Careful identification by an expert is strongly recommended before consuming this or any wild plant. In the United Kingdom, the national collection of wisteria is held by Chris Lane at the Witch Hazel Nursery in Newington , near Sittingbourne in Kent . Wisteria and their racemes have been widely used in Japan throughout
437-563: The plant is spelled Wisteria. This single wisteria vine covers over an acre. The Wistaria Vine has over 1.5 million blossoms and weighs over 250 tons. The plant is on private land and open to the public once a year during the Wistaria Festival. The vine was planted in 1894 by Mrs. William (Alice) Brugman. Brugman purchased the vine from the old Wilson nursery, in Monrovia , for seventy-five cents in 1-gallon bucket. The vine's trunk
460-616: The shortest racemes, 5–7 centimetres (2.0–2.8 in). W. floribunda (Japanese wisteria) has the longest racemes, 90 centimetres (35 in) in some varieties and 120 centimetres (47 in) or 200 centimetres (79 in) in some cultivars . The flowers come in a variety of colors, including white, lilac, purple, and pink, and some W. brachybotrys (Silky wisteria) and W. floribunda cultivars have particularly remarkable colors. The flowers are fragrant, and especially cultivars of W. brachybotrys , W. floribunda , and W. sinensis are noted for their sweet and musky scents. Flowering

Because of their hardiness and tendency to escape cultivation , these non-native wisterias are considered invasive species in many parts of the U.S. , especially the Southeast , due to their ability to overtake and choke out other native plant species. W. floribunda (Japanese wisteria), which has

Molecular phylogenetic studies from 2000 onwards showed that Wisteria , along with other genera such as Callerya and Afgekia , were related and quite distinct from other members of the Millettieae. A more detailed study in 2019 reached the same conclusion, and moved Wisteria to the expanded tribe Wisterieae . As of September 2023 , Plants of
