Wisteria floribunda Alba

Wisteria floribunda 'Alba' is a climbing plant of impressive vigour. This hardy Japanese wisteria is appreciated for its generous flowering in white and fragrant clusters.

Wisteria floribunda 'Alba' is a deciduous climber. It bears medium green leaves with 12 ovate leaflets, 4 to 8cm (2 to 3in) long. The stems twine from left to right (dextrorse stems) on solid supports. In May, it bears pendulous clusters of flowers, measuring 30 to 50cm (20in) long. They are white papilionaceous flowers. The fruits, in the shape of velvety beans, measure from 10 to 15cm (4 to 6in) long.

It is one of the hardiest wisterias. It can withstand temperatures down to -20°C (-4°F). It prefers non-calcareous, deep, fertile, and well-drained soils. It appreciates sunny or partially shaded positions that are warm and sheltered from strong winds. The soil should be enriched with organic matter every year. Prune in February, when the flower buds are formed.  It takes a long time for the plant to establish.

With its 10m (33ft) height, Wisteria floribunda 'Alba' is perfect for dressing walls, railings, pergolas, arbours, and porches for a romantic garden. In summer, its dense foliage will protect your south-facing patio. Take care, as wisteria branches can twist even the strongest supports.
