Botanical Name

CAMELLIA japonica 'Bill Colsen'

Plant Common Name

Bill Colsen Camellia, Camellia, Japanese Camellia

General Description

The camellia ‘Bill Colsen' bears large, semi-double, rose-red flowers in late winter and early spring. Each blossom has 20 petals and 7 "petaloids," and a central cluster of white stamens with yellow anthers. Originating in 1977 as a seedling of 'Julia Drayton', 'Bill Colsen' was selected and named by G.G. Gerbing of Millwood, Georgia. It rapidly forms a broad, rounded, medium to large shrub with oval, glossy, dark green leaves and attractive gray-barked branches. It is one of thousands of named selections and hybrids of Camellia japonica, a broadleaf evergreen shrub that has long been grown and treasured in its native East Asia.

Camellia japonica cultivars prefer dappled sun but will tolerate full sun once established. The soil should be moist, well-drained, and non-alkaline. Shelter them from harsh winter sun and winds, and apply mulch to keep the roots cool and moist. Regular irrigation and applications of fertilizer promote optimal growth and flowering. Prune lightly (if necessary) in early spring, before next year's flower buds form. Camellia japonica cultivars are well suited for foundation plantings, mixed borders, cool greenhouses, and large containers. Their large waxy flowers are excellent for cutting.
