Summary ²

Planera aquatica, or Water Elm is single species in the southeastern United States, a small deciduous tree 10–15 m tall, closely related to the Elms but with a softly, prickly nut 10–15 mm diameter, instead of a winged seed. It grows, as the name suggests, on wet sites. The leaves are 3–7 cm long, with a serrated margin.

Habitat ³

Swamps, streams, lakes, alluvial flood plains, often forming large stands; 0-200m.

Summary ⁴

Planera aquatica, or Water Elmis single species in the southeastern United States, a small deciduous tree 10–15 m tall, closely related to the Elms but with a softly, prickly nut 10–15 mm diameter, instead of a winged seed. It grows, as the name suggests, on wet sites. The leaves are 3–7 cm long, with a serrated margin. Despite its common English name, this species is not a true elm, although it is a close relative of the elms (species of the genus Ulmus). It is also subject to Dutch Elm Disease, a disease which affects only members of the Ulmaceae. It is native to most of the southeast United States. It is hardy down to Zone 7.
