  2. Yes...try Camellia Forest Nursery in Chapel Hill, North Carolina...they carry a great diverse selection of woody plants for the southeast and a few cultivars of Eurya japonica did show up when I just searched on their website. I may later change my zone listing to 7b after this winter...most sources say zone 8 however there are a few plants surviving on very protected sites in zone 7 Washington, DC
