Noted for its unusual upright habit within the Laceleaf Japanese Maples, award-winning Acer palmatum 'Seiryu' is a medium-sized deciduous shrub with small, deeply cut, dissected leaves of great beauty. The delicate spring foliage emerges lime-green with reddish tips, matures to pale green with reddish edges in summer, before turning spectacular gold, pale yellow and a suffusion of orange and crimson in fall. Strong but not overly vigorous, this upright maple tree enjoys a broadly columnar habit and stands out in the landscape. 'Seiryu' means 'Blue-Green Dragon'.
