It is unusual to see an upright-growing dissectum. Almost all other dissectums cascade or weep. Leaves are a pleasing bright green. The lace-like leaves are yellow green and tipped with reddish tones as they unfold in the spring. The color soon changes to a uniform light green, though later in summer, on exposed leaves, the reddish tones reappear on the margins. The deeply cut ferny palmate leaves are highly ornamental and quite spectacular as they turn to strong gold to light yellows with a suffusion of crimson. The bark is a dark, brown-green. It is a delightful addition to any garden. Grows 6-12 inches a year. 

This tree does best in full sun to partial shade. You may want to keep it away from hot, dry locations that receive direct afternoon sun or which get reflected sunlight, such as against the south side of a white wall. It prefers to grow in average to moist conditions. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. For best color, most maples need a location with part day's sun. Morning sun and afternoon part shade is ideal.
