About Camellia

Camellias are members of the same genus as the tea plant, Camellia sinensis, and are among the few substantial shrubs that flower reliably in the depths of winter and early spring. They evolved as understorey plants in East Asian forests, which is the key to placing them: they want shelter, dappled light and acidic, humus-rich soil rather than full exposure. The classic problem of buds browning and dropping before opening is usually caused by early morning sun striking flowers or buds that are still frozen, thawing them too fast.

Growing notes

  • Frost can damage open buds and flowers
  • Prefers part shade and consistent moisture
