To effectively identify Zelkova serrata, a short main trunk, low branching and a vase-shaped habit are main characteristics. It has alternately arranged leaves that are ovate to oblong-ovate in shape with serrated or crenate margins. Zelkova serrata is a medium sized tree usually growing to 30 m tall.

The twigs are slender, reddish-brown turning as gray with age, hairy at first and smooth later. The American elm is a small to medium-sized (to very large) tree, at maturity with spreading branches forming a broad-spreading, fan-shaped crown. These trees have flourished and spread over most of the North Hemisphere, inhibiting the temperate and subtropical regions of North America and Eurasia. All types of elms are tolerant of a wide range of soils and PH levels but, with few exceptions, demand good drainage. The tree also consists of patalless flowers that appear before the leaves and are borne in clusters on jointed stems. Elm’s nutlike fruit is surrounded by a flat, sometimes hairy, wing-like structure referred to as Samara.
