BLUE WISTERIA Wisteria sinensis
Wisteria sinensis (Chinese wisteria) is a woody, deciduous, perennial climbing vine in the genus Wisteria, native to China in the provinces of Guangxi, Guizhou, Hebei, Henan, Hubei, Shaanxi, and Yunnan. While this plant is a climbing vine, it can be trained into a tree-like shape, usually with a wavy trunk and a flattened top.
It can grow 20–30 m long over supporting trees by counterclockwise-twining stems. The flowers are blue, produced on 15–20 cm racemes before the leaves emerge in spring. The flowers have a distinctive fragrance similar to that of grapes. Seed production is often low, therefore becoming difficult to obtain seed.
It is hardy in USDA plant hardiness zones 5-9, and prefers moist soils. It is considered shade tolerant, but will flower when exposed to partial or full sun. Plants can live for over a hundred years.
Wisteria sinensis has secured for itself a place as one of the most popular vines for home gardens due to its flowering.
A one-acre (4,000 m2) specimen located in Sierra Madre, California is recognized by Guinness World Records as the world's largest blossoming plant.
Wisteria sinensis was unknown in Europe before 1816, when several agents working in China sent cuttings back to England. A 200 year-old vine, growing at Griffin's Brewery in Chiswick, London, planted that same year, is often cited as England's oldest living wisteria plant. Over the next several decades the plant became, and remains, one of the quintessential ornamental vines in English gardens. It is most commonly trained along garden walls, along the exterior of buildings, or over a pergola to create avenues of overhanging blossoms during bloom.
Type: Vine or tree

Seed size: Very large. These are the largest Wisteria seeds we have seen! They are large, very dark-brown to black in color, fairly flat, shiny and smooth.
Note: All parts of the plant (including the seeds) contain a glycoside called wisterin which is toxic if ingested and may cause nausea, vomiting, stomach pains, and diarrhea.
Seeds per pack: 3 Large seeds
Germination: Place seeds just below the soil surface of a sterile seed-start mix, and keep moist until germination, which can take 30 to 90 days. Be sure to keep the soil moist until germination. Once growth appears, place the pot in a sunny location.
