This genus is comprised of 45 deciduous, rarely semi-evergreen trees and very rarely shrubs. \u00a0Most elms are large limbed trees forming a domed crown with furrowed or fissured gray bark. \u00a0There found natural occurring in woodland, thickets, and hedgerows in the northern hemisphere and Siberia to Indonesia, Mexico to Japan. \u00a0They have alternate, ovate to elliptic, egg shaped or rounded leaves with prominent, parallel lateral veins and may be single or double toothed margins and with unequally sized bases. The leaves usually color to yellow in autumn. \u00a0Cluster of tiny, bell shaped flowers, each with 4-9 segments joined at the bases, are usually produced from auxiliary buds in spring, but sometimes from leafy buds in autumn, they are quickly followed by green to brown, rounded to elliptic, membranous wing seed capsules. \u00a0Cultivated for their habit and foliage, elms\u2019 are mainly grown as specimen trees. \u00a0Ulmus x hollandica \u2018Jacqueline Hillier\u2019 is suitable for shrub border and for hedging.<\/p>\n
In areas free of Dutch elm disease grow in any well-drained soil in full sun or partial shade. \u00a0Zelkovas are good substitutes where Dutch elm is prevalent.<\/p>\n
