Wisteria

Wisteria (also spelled Wistaria or Wysteria) is a genus of flowering plants in the peafamily, Fabaceae, that includes ten species of woody climbing vines native to theEastern United States and to China, Korea, and Japan. Some species are popular ornamental plants, especially in China and Japan. An aquatic flowering plant with the common name wisteria or 'water wisteria' is in fact Hygrophila difformis, in the familyAcanthaceae.
--> Wisteria, especially Wisteria sinensis, is very hardy and fast-growing. It can grow in fairly poor-quality soils, but prefers fertile, moist, well-drained soil. They thrive in full sun. Wisteria 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 (particularlynitrogen). Wisteria has nitrogen fixing capability (provided by Rhizobia bacteria in root nodules), and thus mature plants may benefit from added potassiumand phosphate, but not nitrogen. Finally, wisteria can be reluctant to bloom because it has not reached maturity. Maturation may require only a few years, as in Kentucky Wisteria, or nearly twenty, as in Chinese Wisteria. Maturation can be forced by physically abusing the main trunk, root pruning, or droughtstress.
