Family
Fabaceae

Wisteria macrostachya 'Blue Moon' is a vigorous and remarkably hardy wisteria, known for its repeat fragrant blooms and ability to thrive in cold climates. This variety is distinguished by its long, hanging clusters of delicately scented lavender-blue flowers, which can appear up to three times per season when conditions are favorable. Its overall habit is climbing, twining, and strong, ideal for covering pergolas, arbors, sturdy fences, and sunny facades. The deciduous medium green foliage, composed of elegant leaflets, creates a dense screen in summer and gives way to a decorative structure in winter. Unlike Asian wisterias, 'Blue Moon' offers excellent hardiness and reliable flowering even in northern regions. Highly ornamental and spectacular when in full bloom, it is a prime choice for creating a lasting and fragrant vertical focal point in the garden.
