The elegant, goblet-shaped flowers of these handsome small trees are among the beauties of spring. Large leathery leaves, smooth gray bark, and yellow fall color add to the seasonal interest. Flowers appear before the leaves, which makes them more vulnerable to late spring frosts and freezes. Many cultivars of saucer magnolia are available, with a wide range of flower colors and shapes.
