Do any hydrangeas do well in moist soil?

What’s your definition of moist soil? If the ground stays saturated or is poorly drained, I would avoid a hydrangea. The Original Endless Summer Hydrangea does well with ample moisture but shouldn’t be in a spot where the roots will be in standing water. Take a look at the Endless Summer planting and care guide for additional information on selecting the right spot in your garden to grow healthy hydrangeas.
