Origin:

  Newfoundland to Florida, west to foot of Rockies  

Sun/Water Requirements:

  Partial/Full sun.
Moderate climate.
Dirr says: "Found naturally in bottomlands, floodplains, swamp forest, ravines and rich woodlands. In habit wet flats where standing water may accumulate in the spring and fall."

Climate / Hardiness Zones:

  Zone 3 to Zone 9

Growth:

  Range: Grows from 50' to 100'.
Dirr says: "Three distinct habits are recognized and include the vase-shped form in which the trunk divides into several reect limbs strongly arched with pendulous branches, the whole tree a picture of great beauty and symmetry; a form with more widely spreading, less arching branches, often called the "oak-form"; and a narrow form with branchlets clothing the entire trunk. Medium to fast growth, 10 to 12' in 5 years; this rate of growth is common for many elms."

Flowers:

  Season(s): Early Spring, Late Winter

Dirr says: "greenish red, in fascicles of 3 or 4 in March, usually late February in Athens, GA. Interesting but not showy."  

Foliage:

  Deciduous
Color: Leaves are dark green in the summer and yellow in the fall.
Dirr says: "great variation in intensity of fall coloration."  

Fruit:

  Color: Red, Green
Season(s): Late Spring, Summer
Dirr says: "May through July, not ornamental"  

Landscape Value:

  Can be used as a shade tree.

Dirr says: "It is by no means true that all American Elms were destroyed with the Dutch Elm Disease; many cities have extensive maintenance programs. The more resistant clones 'Valley Forge', 'New Harmony' and 'Princeton' are worthy of use."

Other:

  Is Salt Tolerant
Is Urban Tolerant
