Plant Common Name

William's Camellia

General Description

The camellia is a tender, broadleaf, evergreen shrub much prized in warm climates for its abundant, showy flowers and glossy, shapely leaves. Camellia x williamsii is a hybrid between the Asian species Camellia japonica and Camellia saluenensis. The hybridization of these two plants was first made by J. C. Williams of Caerhays Castle in Cornwall in the early 1920s.

The beautiful camellias that resulted from this cross are generally quite hardy, large, and produce many flowers for a longer period of time than other camellias. They are upright, dense, slow-growing shrubs with glossy, green leaves. Their rounded flowers may be single, semi-double or double and appear in succession from winter to early spring. The blooms come in a variety of shades from white to pink and red.

Camellias prefer partial shade, but established, regularly watered specimens will tolerate full sun. Evenly moist, acid, well-drained soil is essential. These plants are notoriously slow-growing, slow to establish and shallow rooted. A thick layer of organic mulch will protect the roots and help maintain even moisture. Regular irrigation and applications of fertilizer will help promote good growth and flowering. Prune lightly (if necessary) after flowering, just before growth starts in the spring. These shrubs do not recover well from harsh renewal pruning.

Though hardier than most camellias, William’s camellia is still quite tender. Its evergreen leaves and tender flower buds may suffer from sunscald and wind desiccation in winter, so avoid planting it in highly exposed areas. In the landscape, camellia may be used in hedges, foundations, mixed borders or as a specimen plant.
