Florida sugar maple |
Habit This tree is very similar to the sugar maple (Acer saccharum),
which occurs farther north in the Appalachians. It is a smaller tree
than the sugar maple with a similar large, dense, round crown.
Leaves are simple, opposite, and deciduous. The leaves of the
Florida sugar maple are significantly smaller than those of Acer saccharum,
and are blue-green in color. They are palmate with 5 lobes.
The leaf margins are entire or irregularly toothed at wide intervals.
Fruit
Twigs The twigs are slender, shiny, reddish-brown. The pith is white
and homogeneous.
The bark is light gray and smooth, becoming darker, thicker, and more
furrowed as the tree matures.
The Florida sugar maple occurs on moist soils or on limestone ridges
on the coastal plain and Piedmont areas from southeastern Virginia to Florida
and west to Arkansas and Texas.
This tree is of little value as a timber species, but it makes an excellent
shade tree. It is a source of maple sugar.
