Description
Striped maple is a deciduous, understory small tree/large shrub with a graceful, arching, uneven crown. Twigs and young trunks and branches are smooth with bark starting reddish brown and aging to a bright green with longitudinal, white stripes (thus the common names). The pronounced striping fades with age as older bark returns to reddish-brown. The shape of the leaf resembles the foot of a goose. Leaves emerge pinkish in spring, then age to green in summer and lemon-yellow in fall.
Flower buds are bright red. Unlike other native maples, the green flowers of this species are terminal and pendulous. Striped maple is dioecious (male and female flowers are on different plants). Studies by the US Forest Service indicate the vast majority of A. pensylvancium are male. Fertilized female flowers produce a winged, paired fruit or samara in late summer. Trees need to be 10+ years old before they produce seed.
Fun fact: The specific epithet is a reference to the State of Pennsylvania where this tree is native. Linnaeus misspelled PA.
Excellent shade tolerance; dislikes full sun conditions but may become spindly in full shade. Consistently moist soils are preferred.
