Cornus controversa (wedding cake tree), syn. Swida controversa, is a species of flowering plant in the genus Cornus of the dogwood family Cornaceae, native to China, Korea, the Himalayas and Japan. It is a deciduous tree growing to 50 ft (15 m), with multiple tiered branches. Flat panicles of white flowers (cymes to 3–7 in (8–18 cm) wide) appear in summer, followed by globose black fruit (drupes to 1⁄2 in (13 mm)). Ovate dark green leaves (3–6 in (8–15 cm) long) are glaucous underneath and turn red-purple in autumn. It is cultivated in gardens and parks in temperate regions.[2][3][4]
