Once highly prized shade trees, elms have fallen on hard times. Dutch elm disease (spread by a bark beetle) has killed millions of American elms in North America and can attack most other elm species. Many of the larger elms are appealing fare for various types of beetles, leafhoppers, aphids, and scale, making them time consuming to care for, messy, or both.Ulmus pumila
Native to Russia, northern China. Grows 50 ft. tall, 40 ft. wide. Smooth dark green leaves are 3/4 to 2 in. long. Resists Dutch elm disease and endures cold, heat, aridity, and poor soil—but has brittle wood and weak crotches and is not a desirable tree. Possibly useful in holding soil against erosion; fast growth also makes it suitable for windbreak or shelter belt. Papery, winged seeds disperse seedlings over wide area.
