The Story

Plant Bio

Wisteria macrostachya, or Kentucky Wisteria, is a North American native vine prized for its long, pendulous flower racemes. It is less aggressive than its Asian counterparts, making it a more manageable choice for gardens. 'Summer Cascade' is noted for its extra-long, 12-inch flower clusters and its reliable blooming on new wood, ensuring flowers even after a harsh winter. It can rebloom lightly in summer.

Uses & Benefits:

Creates a breathtaking display with its long, cascading clusters of fragrant lavender flowers, evoking a romantic, old-world charm on any structure it adorns.

Provides dense summer shade when grown over a pergola or patio structure, helping to cool outdoor living spaces. It is also more manageable than Asian wisteria varieties.

The flowers are a rich source of nectar for bees, butterflies, and other pollinators. The dense growth can provide shelter and nesting sites for birds.
