Clematis paniculata, also known as Clematis terniflora, is a vigorous late-season climber prized for its abundant, star-shaped white flowers with a sweet vanilla-like fragrance. It blooms in late summer to fall, often covering the plant in a dense cascade of blossoms that attract pollinators and provide strong seasonal interest. Ideal for covering fences, arbors, and large structures, it thrives in full sun to partial shade and is valued for its rapid growth, reliable performance, and highly fragrant floral display.
