Known for its cascading clusters of fragrant flowers in shades of purple, blue, and white, wisteria can create a breathtaking display in your garden. This vine is a vigorous grower and can quickly cover a trellis, providing a beautiful canopy of flowers. Wisteria is also known for its attractive foliage, with its pinnate leaves adding texture and interest to your outdoor space.
