Shirofugen

Shirofugen is a cultivar of Camellia japonica, an evergreen flowering shrub in the Theaceae family. It is widely grown as an ornamental plant in gardens and parks, valued for its striking white blooms.

The plant typically forms an upright to rounded shrub, reaching about 2–4 meters in height with glossy dark green leaves. Flowers are large and come in a semi-double to double form, composed of many white petals. In some conditions, a faint pink flush may appear near the center of the bloom or at the base of the petals, but the dominant color is white. Blooming occurs in late winter to spring, depending on climate and cultivation.

Origin and naming: Shirofugen originated in Japan and has been cultivated there for many decades. The name Shirofugen is the Japanese designation used for this cultivar.

Cultivation: Shirofugen prefers acidic, well-drained soil and partial shade. It benefits from mulching and protection from strong afternoon sun in hot climates. Regular watering during the growing season is important, but the plant should not be waterlogged. After flowering, prune to maintain shape and remove dead or weak wood. Fertilize in spring with a balanced, slow-release camellia fertilizer.

Pests and diseases: Like other camellias, Shirofugen can be affected by pests such as scale insects and spider mites, and by diseases including camellia leaf gall and root rot. Good cultural practices, proper spacing, and regular monitoring help reduce risk.

Uses and significance: Shirofugen is commonly used as a specimen plant, in shade gardens, or as a flowering hedge in appropriate climates. Its white flowers provide seasonal interest during late winter and spring.
