About Japanese wisteria
Wisteria floribunda, or Japanese Wisteria, is a magnificent woody climber renowned for its long, pendulous clusters of fragrant purple to blue flowers, which can reach up to 90 cm in length. Its pinnate, deciduous leaves complement the abundant spring bloom. It is ideal for pergolas, arbors, or for covering sturdy walls and structures, creating spectacular floral cascades.

Care tips
It requires full sun (at least 6 hours daily) for abundant flowering and well-drained soil rich in organic matter. Watering should be regular during the growing and flowering season, reducing it in winter. Strict formative and flowering pruning in winter and summer is crucial to control its vigor and stimulate blooming. Avoid excessive nitrogen fertilizer, as this will promote foliage growth at the expense of flowers.
