Similar species: Acer ginnala is one of the only maples with fragrant flowers. Its very long middle lobe easily distinguishes it from other three-lobed maples.
Habitat and ecology: Occasionally escapes from cultivation into old fields and pastures, vacant lots, disturbed or undisturbed woods.
Occurence in the Chicago region: non-native
Notes: A. ginnala is a cultivated species from Asia. Cultivars are often selected for their bright red fall color.
Etymology: Acer is derived from a Latin word meaning sharp, referring to the hardness of the wood. Ginnala comes from the Chinese common name for the plant.
