Abstract
A new cultivar of Styrax plant named ‘EVENING LIGHT’ which exhibits an upright vase-shaped habit with foliage that emerges and remains rich dark purple to black when grown in full sun. When grown in shade, the older lower leaves of ‘EVENING LIGHT’ become dark olive green or bronze in color. ‘EVENING LIGHT’ bears pure white to very pale pink bell-shaped flowers in May and June. ‘EVENING LIGHT’ prefers sandy soil and is hardy to USDA Zone 5. In combination these traits set ‘EVENING LIGHT’ apart from all other existing varieties of Styrax known to the inventor.
