These are beautiful flowering evergreen shrubs and trees which originate in China, Japan and neighbouring countries.
Garden forms are derived from only a few species, but with many thousand hybrid varieties. The leaves of one species, Camellia sinensis, are dried to make tea.
Trebah has a large and varied collection of camellias. They start flowering before Christmas (Camellia sasanqua 'Hugh Evans', and Camellia japonica 'Nobilissima') and continue until mid summer.
