This versatile group of easy-to-grow, broad-leafed evergreens combines handsome foliage with fragrantthough inconspicuousflowers (white, in most cases). Most are large shrubs that can eventually reach the size of a small tree. Use them as tall screens, hedges, or foundation plantings. They tolerate many soils (including heavy clay), accept heavy pruning, and do well with little moisture or regular garden watering. Some- what resistant to damage by browsing deer.
