Camellia japonica 'Gunsmoke' is a vigorous, upright evergreen shrub prized for its large (5–6 inch), semi-double, red flowers with yellow stamens that bloom from winter to spring. Ideal for USDA Zones 7–9, it grows 8–10 ft tall and 6 ft wide, thriving in partial shade and acidic, well-drained soil, making it excellent for hedges, screens, or containers.
