Scientific classification


See Elm species, varieties, cultivars and hybrids

Elms are deciduous and semi-deciduous trees,[1] found throughout the Northern Hemisphere from Siberia to Indonesia, Mexico to Japan. They have alternate, simple, single- or doubly-serrate leaves, usually asymmetric at the base and sharply pointed at the tip.

Elms are hermaphroditic, having perfect flowers, and which, being wind-pollinated, are without petals. The fruit is a round samara.

Elms take many decades to grow to maturity.
