Answer: My first choice would be camellia. It likes the same soil pH (slightly acidic) as azalea, will remain green all year, and has the added bonus of blossoms. Camellias can become quite stately with age and can be allowed to remain shrubby, or the lower branches can be trimmed to make the plant resemble a tree.
There are so many cultivars available, your next decision will be what color!
