Distinguishing traits. With its soft delicate feathery foliage, sweeping fluid form, and dazzling seasonal color, there aren't many ornamental trees more recognizable or desired than Japanese maple.

Japanese maple loses its leaves in winter, as with all maples, but is proceeded by a striking display of fall color in hues ranging from golden bronzes and yellows to rich reds and deep purples.
