The Q&A Archives: Hydrangea Vine

Question: I just planted a hydrangea vine under a cyclone fence on which I hope it will grow. The mother plant is growing on the stucco sided garage wall. Does the hydrangea need masonry that its roots can grow in to or will it entwine in the cyclone fence?

Answer: I don't think I have ever seen this tried; instead I have seen this plant on buildings (stone, brick, stucco) and on free-standing stone walls and on sturdy wooden pergolas and growing up strong old oak trees. Part of the reason may be that it grows to 60 feet or so and becomes rather heavy, thick and woody. If it does manage to reach the top, this could deform your cyclone fence by bending the top cross piece due to the weight alone. This vine climbs using little hairy or rootlike holdfasts so it needs a rough surface to cling to. If you twine it through the fence to help it climb, it will eventually outgrow the holes and become strangled as a result. For a chainlink or cyclone fence I think a twining vine such as clematis or honeysuckle would be a better bet.
