This tree is discarded by Maynard, who says: "It soon takes an irregular form, is easily broken by wind and ice, and is rather short-lived." As found native in the Northwest this is not correct. If properly grown in nursery with straight stem, it makes a handsome round-topped tree, is not as liable to injury from wind or ice as most other trees, and has proven a long-lived species. No shade tree yet planted in the prairie States makes a denser shade.
