Large leaves, many fruits per cluster, seems to fit Cotoneaster lacteus.
Cotoneaster lacteus (late cotoneaster) is a species of flowering plant in the genus Cotoneaster of the family Rosaceae, native to the Yunnan Province of China. It is a large evergreen shrub growing to 4 m (13 ft) tall and wide. Clusters of white flowers are followed by masses of small, globose, red fruits (pomes) in autumn. Unusually for this genus, the fruits are avoided by birds, hence garden escapes are rare, and the fruit persists on the plant
