I have a mass planting of Formosa along my back fence area. In front I added some dwarf gardenia as they are planted right on the shade edge.

In my photo you can see there are two gaps between the Formosa and gardenia. How would it look to add two dwarf white azaleas in front of the formosa? Does it look like I have enough room? I know the Formosa will grow larger and I don'nt to crowd the new azaleas but I found some encore dwarfs that say 2-3ft round. I can push the gardenias up some but I just kept them close to the grass line.
