Outstanding Qualities Styrax japonicus ‘Emerald Pagoda‘ was selected by the late J.C. Raulston at North Carolina State University in and the U.S. National Arboretum. It was brought back as cuttings from Korea because the wild plant showed exceptional vigor and was markedly distict from the native population. It is the most vigorous and largest flowered of the Styrax japonicus selections. The star-like flowers are 1inch across and slightly fragrant and are almost more beautiful when they begin to drop and carpet the ground beneath the tree. This selection has larger than average leaves that are dark green and leathery in texture. It will grow as on understory tree or make a striking specimen in an open situation. Fall color is a luminous yellow. If grown in the woodland combine with ferns, hostas, Solomon’s seal, epimediums and the like. This styrax selection is considered by some to be the most distinctive and striking.
Culture Styrax thrives in full sun or part shade. It does best with humus-rich, well-drained soil and regular watering during summer dry spells. In general, the tree is disease resistant. It can lose braches in winter for no apparent reason; these should be pruned out in spring.
Growing Habit ‘Emerald Pagoda‘ is an upright, somewhat columnar deciduous tree that grows to 10 feet high and 8 feet wide in ten years. It matures at 20 by 30 feet high and 20 feet wide. It is slow growing.
