Pee gee hydrangeas

Question

I purchased single stemmed (tree) pee gee hydrangeas. I’m hoping to grow them as multi-stemmed shrubs in my yard. Is it possible? Will they start to develop branches from the trunk on their own?

Answer 1

They can develop suckers on the trunk but they will not shape themselves into a shrub shape. They most likely are grafted onto a plant stock specifically for this standard shape.
