Wisteria floribunda Macrobotrys

Wisteria floribunda 'Macrobotrys' is a spectacular variety of Japanese wisteria. Its pendulous blue-violet flowers are grouped in long trailing clusters that can measure up to 1m (3ft) in length!

Wisteria floribunda 'Macrobotrys' has deciduous leaves with 12 ovate leaflets that are medium green in colour and measure 4 to 8cm (2 to 3in) in length. The stems twine from left to right on sturdy supports. In May, pendulous clusters of slightly fragrant blue-lilac papilionaceous flowers are formed, measuring 50cm (20in) to 1m (3ft) in length. The fruits, in the shape of velvety beans, measure from 10 to 15cm (4 to 6in) in length.

This is the hardiest of wisterias, tolerating temperatures down to -20°C (-4°F). It takes a long time to establish and thrives in non-calcareous, fertile, deep and well-drained soils in sunny or semi-shaded positions that are sheltered from strong winds. The soil should be enriched with organic matter every year. Pruning should be done in February when the floral buds are formed.

With its height of 8m (26ft), Wisteria floribunda 'Macrobotrys' is used to cover walls, railings, pergolas, arbours, and porches for a romantic garden.

Wisteria branches can twist even the strongest supports.

Beware! All parts of wisteria are toxic if ingested!
