Well-behaved, relatively small shade trees. Long life and good habits as street trees. Slow to moderate growth rate. Very hard, tough, heavy wood. Dark green, sawtooth-edged leaves color up in cold-winter climates, hang on late in season. Fruits (small, hard nutlets in leaflike bracts) are carried in attractive drooping clusters to 5 in. long. Mature trees need little or no pruning.
