Water Elm
Planera Aquatica


The Water Elm is a medium sized, deciduous tree in
the southeastern part of the United States. (1) (2)
It grows a small, prickly berry rather than a regular
Elm tree that grows dry, winged seeds. (1)
Also known as a Planertree, you can easily tell it
apart from other trees by its even base. (2)
The Planertree has a long life span and will reach
maximum height at 50 feet after 20 years. (7)

usually reach a height of
35 feet. (3) But can
reach a maximum of 50
feet. (7)

The bark of a Planertree is usually scaly and patchy.
The bark is grayish brown on the surface with reddish
brown patches. (3)

The twig of a Water elm is slender with the same
coloring as the bark. They are usually hairy initially
but later on become smooth and hairless. (3)


The leaves of a Planertree
are simple and alternate.
The leaf has a margin
present and is ovate, or

They usually don’t exceed
three inches long or 1 inch

You would find a Planertree in a wet habitat. They
grow bordering or even in standing water. (10) The

United States, primarily the Coastal Plain of North
Carolina and Louisiana. (2)
