'Seiryu' is a very unique Japanese maple that is unlike any in the world. Because it is so different, it is an incredible addition to any maple collection. First, it is extremely rare to have a dissectum grow in an upright form. Almost all other dissectums grow in a cascading or weeping form. 'Seiryu' is a strong upright grower with just the right amount of vigor. As 'Seiryu' matures it becomes multi-branched and gradually thickens to nice and shapely form. Seiryu's spring foliage is a refreshing bright green color. Each lace-leaf tip has a splash of reddish tones as it unfolds. The leaves soon change to a uniform light green. In late summer reddish tones reappear on the exposed leaves. Seiryu's fall colors are quite spectactular and range from gold to light yellows with a suffusion of crimson in most leaves. The lace-leaves are slightly smaller and much thinner than other green dissectums.
