A deciduous small tree or large shrub to around 5m, with oval-shaped dark green glossy foliage, turning to orange, red and yellow in autumn. Masses of overlapping white flowers (bracts) appear in mid-summer. Sterile, so therefore does not produce fruit. An ideal choice for smaller gardens and courtyards
