Family:Hydrangeaceae

Climbing hydrangea boasts lush green leaves, produces white blooms in mid-summer, showcases vibrant yellow hues in the fall, and features eye-catching exfoliating bark during winter. This vine is an early summer bloomer, making it ideal for creating a striking visual impact on brick or concrete walls, arbors, gazebos, or virtually any standalone garden structure. It ascends and adheres not only through twining but also by utilizing aerial rootlets. With its lateral branches, this woody vine often resembles a shrub and is indigenous to wooded valleys, stream banks, and rocky mountain slopes.

While climbing hydrangea can be slow to establish and may take time to flower after being transplanted, it thrives in rich, well-drained, and moist soil. It is adaptable to both sunny and shaded environments and can reach heights of 60 to 80 feet. Once it is well-established, it typically faces minimal pest issues.
