Answer: When a plant tag recommends full sun to part shade, it means the plant will grow in a site that receives all day sunshine (8 or more hours of direct sun), or a site that gets a few hours of either morning shade or afternoon shade. Some plants, such as Japanese maples, appreciate shade from hot afternoon sunshine. Others, such as Escallonia or Kalmia, are adaptable enough to grow in either fully sunny sites or in sites receiving a few hours of either morning or afternoon shade.
Hope this clarifies things for you!
