Summer Cascade Wisteria (Wisteria macrostachya 'Betty Matthews') is a showy, cold-hardy flowering vine that brings elegant, fragrant cascades of dark lavender racemes to your garden beginning in early summer. Discovered in Minnesota, this FIRST EDITIONS selection is more reliably hardy than many other wisterias, thriving in USDA Zones 4-8, and it blooms on new wood-meaning you get flowers even on younger growth. Its long, trailing flower clusters open in rich lavender and gracefully fade, offering multi-season interest, which is enhanced by interesting seed pods in late summer. Whether covering an arbor, pergola, fence, or trained as a vine, Summer Cascade is perfect for adding vertical drama, fragrance, and natural beauty to the landscape. Its vigorous growth, insane bloom display, and dependable hardiness make it a standout choice among flowering vines for both Northern and Southern gardens alike.
