Cercidiphyllum Japonicum Cercidiphyllum japonicum is a large deciduous tree grown for its attractive heart-shaped foliage, which changes colour as the seasons progress. Young leaves are bronze when they appear, turning bright green in summer, & then changing again in autumn to stunning shades of pink, orange & yellow. The best colours are produced when the tree is grown on moist, slightly acidic soils. An added bonus is the burnt-sugar scent of the fallen leaves. Flowers May-June. Height 301cm+.
