It is an evergreen shrub growing to 5 m tall. The leaves are broad elliptic, 3–7 cm long and 1.2–3 cm broad, with a finely serrated margin. The flowers are 5–7 cm diameter, with 5–8 white to dark pink petals.
History and uses
At the beginning of the Edo period, cultivars of Camellia sasanqua began appearing; the first record of the cultivars of this plant was made by Ihei Ito (1695–1733). In Japan, it is not considered to be a true Camellia as the Japanese call it Sazanka (サザンカ, 山茶花).
Camellia sasanqua was not known in western societies until in 1820 Captain Richard Rawes of the East Indiaman Warren Hastings brought Camellia sasanqua var. stricata to his relation, Thomas Carey Palmer, of Bromley in Kent. Then in 1869, Dutch traders imported some specimens into Europe. It has now also been introduced to Australia, New Zealand and the United States.
It has a long history of cultivation in Japan for practical rather than decorative reasons. The leaves are used to make tea while the seeds or nuts are used to make tea seed oil, which is used for lighting, lubrication, cooking and cosmetic purposes. Tea oil has a higher calorific content than any other edible oil available naturally in Japan.
Camellia sasanqua is valued in gardens for its handsome glossy green foliage, and fragrant single flowers that can range in color from white to deep pink and are produced extremely early in the season. Various cultivars have been selected, of which 'Crimson King', 'Hugh Evans' and 'Jean May' have gained the Royal Horticultural Society's Award of Garden Merit.
