Climbing Hydrangea
Hydrangea anomala subsp. petiolaris
vineverifiedReviewed by the GreenScout Team
A vigorous, deciduous climbing vine that slowly clings to surfaces via aerial rootlets, producing showy white lacy flower clusters in early summer against glossy green foliage. Mature plants develop exfoliating cinnamon-colored bark that adds winter interest. It reaches 30–60 feet at maturity and prefers shade.
