 The tree grows from 15-30 m tall and may live up to 300 years. Where forest-grown, the crown is cylindrical and upright with short branches, and is narrower than most other elms. Rock Elm is also unusual among elms in that it usually has a [[monopodial]] growth habit. <ref name=Bean> Bean, W. J. (1981). ''Trees and shrubs hardy in Great Britain'', 7th edition. Murray, London. </ref>. The [[bark]] is grey-brown and deeply furrowed into scaly, flattened ridges. Many older branches have 3-4 irregular thick corky wings. It is for this reason the Rock Elm is sometimes called the Cork Elm.

+The [[leaf|leaves]] are 5 - 10 cm long and 2 - 5 cm wide, [[leaf shape|oval]] to [[leaf shape|obovate]] with a round, symmetrical base and acuminate apex. The leaf surface is shiny dark green, turning bright yellow in autumn; the  underside is pubescent. The [[perfect flower|perfect]] [[apetalous]], wind pollinated [[flower]]s are red-green and appear in racemes < 40 mm long two weeks before the leaves from March to May, depending on the tree's location. The [[fruit]] is a broad ovate [[Samara (fruit)|samara]] 13 - 25 mm long covered with fine hair, notched at the tip, and maturing during May or June to form drooping clusters at the leaf bases. <ref name=White>White, J & More, D.
