Product description
This Japanese cultivar is the undisputed queen of dramatic floral displays, boasting pristine white flower tassels that can reach an astonishing two feet in length. The blooms emerge in late spring just as the fresh green foliage begins to unfurl, creating an incredibly elegant, cascading effect. It is a highly vigorous grower that will quickly cover any structure it is allowed to climb.
To care for 'Alba', you must be mindful of its climbing habit—Japanese wisterias naturally twine clockwise, so always guide new shoots in this direction to prevent the stems from snapping. Because the flower tassels are so incredibly long, it is best planted over a pergola where the blooms can hang straight down unobstructed, rather than flat against a wall. Keep the soil moist but well-drained, and never skip its required summer and winter pruning sessions.
Please Note: When purchasing plants, please consider that each live item is unique and may therefore differ from the images shown, which are for illustration purposes only. The plant will be supplied in a growers pot. Depending on season, some plants may be pruned back to encourage growth and deciduous plants may arrive without leaves.

Garden Plant Size Guide
Plants in larger pots can be multiple years older than their smaller counterparts with more mature root systems and foliage. This makes them able to thrive as a full size plant in your garden quicker than smaller alternatives.
The most common size of pot that garden plants come in are 9cm/1L/3L/5L this is in reference to the diameter at the top of the pot.
9cm potted plants still remain the most popular cost effective option though, they just may take a little patience to allow them to grow into full maturity once planted in your garden.

Instructions
Top Tip
The Wisteria Alba's pristine white flower tassels are incredibly long (often reaching over two feet). Plant them on an overhead pergola rather than a flat wall so the blooms can hang straight down completely unobstructed.
How to Water
To water Wisteria Alba, soak deeply once a week in year one to build strong roots. Once mature, let the topsoil dry out, but keep it moist while its long white racemes develop. Always water the base.
How to Plant
To plant Wisteria Alba, dig a hole twice as wide as the rootball but exactly the same depth. Enrich the excavated soil with a generous scoop of compost to ensure a nutrient-rich loam. Place the vine in the hole, making absolutely sure the knobbly graft union sits safely above the soil line. Backfill firmly, tie the main stem clockwise to your pergola, and water deeply to settle the roots.
