Plant a little more compact than 'Red Robin' and with more regular growth, easier to form in container. The colors are however less vivid.
Photinia are evergreen shrubs of East Asian origin. The fraseri hybrids were initially selected by Fraser nurseries (Alabama, 1955) and are a spontaneous cross of glabra (Japan) x serrulata (syn serratifolia, China). 'Red Robin' is the first color selection in these hybrids, made in New Zealand in the 70's. 'Robusta Compacta' is a selection of Minier Nurseries (1991).
'Robusta Compacta' is a selection of 'Red Robin' with more rounded and regular shape. The young leaves and shoots are orange-red, then green after 15 days-3 weeks. Since the plant can grow up to 3 times a year depending on the growing conditions, it is often very colorful. In mid-spring, corymbs of white flowers appear.
