Large group of tropical evergreen shrubs with handsome foliage, showy clusters of flowers. They take salt air and prefer fertile, well- drained, acid soil; plants suffer from chlorosis (yellow leaves with green veins) in alkaline soil. Subject to a host of insects and diseases; difficult to keep healthy without constant vigilance. Not usually browsed by deer.
