Most shade tolerant hydrangea
I have a wooded backyard with tall oak and tulip trees surrounding a lawn. At the edge of the lawn I have several mophead hydrangeas that are doing great. However, I want to plant some hydrangea under the trees as part of a woodland garden. Lower limbs on the trees are trimmed so there is filtered light but I still need some shade loving hydrangea. What type might perform well in such a setting? Thanks in advance!
