Depends on where in the world you are.

It depends a bit on the type but most azaleas will flower best if they receive at least some direct sun. It also depends on location and the late spring/early summer climate as to how much sun they will be happiest in.

I have a couple leftovers of different varieties and different colors. Was going to put under a paperbark maple as a tree ring. But the maple isn’t very mature (2 years old) and they’re going to get blasted with sun for quite a few years told the tree provides more shade.

Ok. Found out I have some Gable and Girard varieties… evergreen and semi. And a Delaware Valley white.
