The leaves of Acer platanoides are roughly similar
to Acer saccharum, from which it can be easily distinguished
by its milky white sap and purple (or green with purplish tint) buds
as compared to the clear sap and medium brown buds of Acer saccharum.
The fruits (samaras) of
the two species are also very different. Several horticultural varieties
of Acer platanoides are planted in Wisconsin, including a broad
range of tree shapes and leaf colors. Leaf
color can range from dark purple to green. Acer platanoides is an introduced species, widely
planted as a street or yard tree and escaping in the southern half of
the state where it may become an invasive species. It is present as
an escape in the City of Green Bay where it has become established in
low numbers even in forests with intact canopies. |
