The Q&A Archives: Climbing Hydrangea In A Container?

Question: I just purchased a Monrovia hydrangea petiolaris and want to grow it over a wall of my house. Is it possible to grow this plant in a large container? I don't require it to become too big but would it survive the winter in a large container?
Also.. will the climbing roots of the plant damage the wall? I have heard that clinging ivy causes damage on walls ..does this plant have any problems like that?
thank you for your help!!

Answer: This plant grows and clings by root hairs and could damage a wall that was not sound to begin with. A mature vine will be heavy and could potentially pull stucco off of a building as well. This would be true of any clinging vine.

It is always risky to grow a plant above ground in a container, so the best bet would be to sink the container in the ground for the winter or otherwise insulate it so that the roots are protected not only from cold but also from temperature swings.

This plant might not be the most satisfying container candidate as it takes several years to become established and begin to grow and several years or longer to begin blooming. It would be difficult to renew the soil without disturbing the plant and possibly causing even more than the normal wait.
