Camellia x williamsii are a highly regarded set of hybrids that grow to about 5m (16ft) high and are well suited to most gardens. They shed spent flowers, unlike some varieties of C. japonica, and are able to recover themselves in new blooms after periods of severe weather.
Camellia x williamsii `Bow Bells` is an evergreen, upright, spreading shrub, producing small, lance-shaped, medium green leaves. A profusion of cup-shaped, single, red-pink flowers with deeper pink centres and veins are borne.
