Remember that all fall blooming or Camellia sasanqua can grow in either sun or shade while the spring blooming Camellia japonica needs at least afternoon shade.
Be sure to use a well drained soil medium when planting any Camellia as they prefer less watering than you might think. In NC our soil is clay so we prefer to use pine bark soil conditioner when planting Camellia, Rhododendron, Mountain Laurel, and Azalea.
