Wisteria floribunda ‘Jissai’
An Abundant and Graceful Japanese Wisteria with Soft Lavender Charm
Wisteria floribunda ‘Jissai’ is a vigorous and free-flowering deciduous climber known for its elegant, pendulous racemes of soft violet-lavender blooms. A standout among Japanese wisterias, ‘Jissai’ offers a perfect balance of floriferous performance, manageable growth, and ornamental value — making it a superb choice for garden structures such as pergolas, trellises, and walls.
Key Features
Elegant, Abundant Flowers
‘Jissai’ produces long, cascading flower racemes typically 30–50cm (12–20 inches) in length. The soft lavender blooms appear in late spring to early summer and are delicately fragrant, attracting bees, butterflies, and admirers alike.
Reliable and Free-Flowering
This cultivar is well-regarded for flowering more freely and consistently than some traditional wisterias once established, with occasional light repeat flowering later in the season.
Vigorous but Manageable Growth
With a twining clockwise habit, Wisteria ‘Jissai’ can reach heights of 6–8m (20–26ft) with proper support, making it suitable for medium to large garden spaces. Its well-branched form and moderate vigour make it easier to manage than more rampant varieties.
Lush Foliage and Seasonal Interest
Bright green, pinnate leaves provide a soft backdrop to the cascading flowers and turn golden yellow in autumn for a second season of colour.
Growing & Care Guide
-
Position: Prefers full sun to encourage maximum flowering, though it can tolerate partial shade.
-
Soil: Moist, well-drained soil is ideal — thrives in fertile, slightly acidic to neutral ground.
-
Support: Requires strong, permanent support such as a pergola, arbor, or robust wall wires to climb and display flowers fully.
-
Hardiness: Fully hardy in the UK and well-suited to temperate climates.
Care Tips
-
Pruning: Prune twice annually — once in summer (July/August) to shorten new growth, and again in winter (January/February) to promote flower bud development by cutting back to 2–3 buds.
-
Feeding: Apply a potassium-rich fertiliser in early spring to support flowering rather than leafy growth.
-
Watering: Ensure regular watering during dry periods, especially in the first year and while flower buds are developing.
-
Training: Train young plants carefully to establish a framework — tie in new shoots and guide growth early on for best structure.
