This vigorous deciduous climber has a twining habit and is known for its stunning display of large, fragrant, deep purple, double flowers that bloom in cascading racemes during late spring to early summer. Hardy in Zones 5-9, it thrives in full sun and prefers well-drained, moderately fertile soil with good moisture retention. This vine showcases green pinnate foliage that turns yellow in the fall, adding seasonal interest. It is an excellent choice for covering pergolas, walls, or fences, creating a dramatic vertical element in any garden. While deer-resistant, it is important to provide sturdy support as this robust climber can grow 20-30 feet tall and requires regular pruning to maintain its shape.
