| Ulmus americana
American elmA large oval to rounded shade tree with distinctive arching branches offering a formal vase-shaped habit. Once used heavily as a street tree for its stately arching branches, it forms a cathedral effect over neighborhood streets. Dutch elm disease, rapidly spread by the Elm Bark Beetle and root grafts, brought about the quick demise of this beautiful species. Aggressive treatment regimes have allowed many trees to remain in some areas. Current strategy is to use resistant cultivars.| Habit: | Vase-shaped arching branching with a narrow to broad-rounded crown; ends of branches can be pendulous, lightly horizontal, or mostly upward arching | | Size: | 65-90' high | | Color: | Green to dark green | | Texture: | Medium-fine texture during growing season, medium in winter | | Hardiness: | Zone 2b USDA | | Habitat: | Native over the Eastern half of the United States and lower Canada, Maine - Florida - Texas - Saskatchewan, Canada | | Family: | Ulmaceae | |
