Wisteria floribunda ‘Macrobotrys’
A Spectacular Japanese Wisteria with Extra-Long Cascading Blooms
Wisteria floribunda ‘Macrobotrys’, also known as the Silky Wisteria, is one of the most show-stopping varieties of Japanese wisteria. Renowned for its exceptionally long racemes, often reaching up to 1 metre in length, this vigorous climber brings breathtaking drama and romance to pergolas, archways, and large walls. The richly scented, lilac to violet flowers appear in great abundance in late spring, creating a dazzling curtain of bloom that sways gently in the breeze.
Key Features
Extra-Long Flower Clusters
The standout feature of ‘Macrobotrys’ is its extraordinarily long flower racemes, which can grow to 90–100cm (35–39 inches) in ideal conditions — among the longest of any wisteria. The soft violet blooms are lightly scented and bloom in elegant succession from top to bottom of each cluster.
Vigorous Growth and Majestic Form
This variety is a strong-growing climber that can reach 8–10m (26–33ft) or more with support. It is ideal for covering large garden structures where its floral cascades can be properly displayed.
Scented Spring Spectacle
Flowering from late May into June, the blooms are lightly fragrant with a sweet, floral perfume. The sheer volume and length of the flowers create a dazzling spring display.
Seasonal Foliage
The bright green, pinnate leaves form a soft, feathery backdrop to the flowers and take on buttery yellow tones in autumn, adding extra seasonal interest.
Growing & Care Guide

-
Support: Needs sturdy structural support due to its mature size and weight of the flowers.

Pruning: Prune twice a year — in summer (July/August) to cut back long new shoots to 5–6 buds, and in winter (January/February) to 2–3 buds to promote flowering spurs.
-
Watering: Water regularly during the establishment phase and during dry spells in spring and summer.
-
Feeding: Apply a balanced or low-nitrogen, high-potassium fertiliser in spring to encourage flowering.

Training: Guide main stems onto the support early, tying in shoots to establish a strong framework.
