Transform Your Garden with Wisteria macrostachya 'Blue Moon'

Wisteria macrostachya 'Blue Moon', a member of the pea family (Fabaceae), is prized for its show-stopping cascades of fragrant, lavender-blue flowers. Unlike many wisterias, this hardy North American variety is renowned for blooming up to three times each season—typically in late spring, midsummer, and early autumn—ensuring your garden remains vibrant for months.

Planting & Care Tips

• Watering: Water regularly during the first growing season to establish roots; drought tolerant once mature.
