Why not try an azalea. Formosa gets about 6ft tall and likes a slightly
acidic soil. They come in white, purple, pink or red

Botanically speaking, Azaleas are Rhododendrons. But did you mean
Pieris, which seems to match your description better? (There is a Pieris
formosa; I don't know of a Rhododendron formosum.)
