Wisteria sinensis Prolific or Wisteria Blue Sapphire is a deciduous climber of Chinese origin native to about seven of the more south easterly provinces such as Guangxi, Guizhou and Hubei. Although a climbing plant, and unlike the Japanese wisteria growing in an anti-clockwise manner, it can also be cultivated into a tree shape more often with a flat top. The flowers always open before the leaves have fully expanded and appear simultaneously in April to June and although shorter in length than the Japanese variety they can be much more prolific. A longer-lived variety than the floribundas, it can survive for over 100 years, it will only begin to flower in its adult stage which could be 20 years or more, however if purchased as a grafted plant this time could be substantially reduced. As with all wisteria it will need a sturdy framework for support such as a pergola or garden arch, or if growing against a wall, straining wires to hold it up.
Wisteria Blue Sapphire is best grown in full sun and although it is said to tolerate some shade it flowers best in a sunny situation. It will grow to between 20-30 metres in length over a period of time and when in flower gives off a light perfume. To encourage flowering for the next season the plant should be pruned regularly twice a year, first in August then in February this will also help to keep it from going wild.
With Wisteria Blue Sapphire being supplied as pot grown it can be planted at any time of the year as there is no disturbance to the root system. This will help the plant get its roots down more quickly and therefore the top growth will benefit.
