Hello gardeners! We are keen to plant hydrangeas in our front yard and I like both the smooth hydrangea and the mophead hydrangea. We live in Melbourne, Australia. We have two garden beds. One is under a very large gumtree and gets morning sun and afternoon shade. The other garden bed gets only dappled sun. Which species of hydrangea (mophead or smooth) would be suited to the garden bed under the gumtree (given that the tree will suck nutrient and moisture from the ground)? Which species of hydrangea (mophead or smooth) would be better suited to the garden bed with only dappled sun (mostly shade)? Thank you in advance!
