The leaves are bright green in color during the growing season and triple lobed. In the Fall the leaves change to a pale yellow and tend to fall earlier then other decidous trees in the same area. The bark is green with white stripes when young, the green darkens to a reddish brown when mature. The small yellow-green flowers bloom in pendulous form, appearing on 6 inch long racemes, each flower within the group is usually only about 1/3 of an inch. These flowers appear in the Spring (usually May depending on the area).

Striped or Snakebark Maple from it's unusual and appealing bark, which is greenish in color when young and marked with white striped (generally vertically). Stripes may vanish over time as the older bark turns reddish brown and the white begins to darken or fade.
Goosefoot Maple - the broad leaves that are triple lobed and often compared to a goose foot in shape.
Moosewood - Moose and white tailed deer often browse the leaves and young twigs hence the name Moosewood.
Whistlewood - Whistles can easily be carved from branch sections, hence the common name of whistlewood.
