Camellia japonica
Camellia japonica is the classic garden camellia grown for its evergreen leaves and showy winter to spring flowers. It stands out for its many formal double and semi‑double forms. It performs best in bright dappled shade or morning sun with protection from hot afternoon sun. It prefers acidic, organic, well‑drained soil and steady moisture. Near the cold edge of its range, a sheltered site reduces bud drop after late freezes. Typical hardiness is USDA zones 7 to 9.
