Discussion
Aucuba japonica has been cultivated in the United States for nearly a century, but naturalized plants appear to be recent escapes from cultivation in Orange County, North Carolina (A. S. Weakley 2012), and King County, Washington (P. F. Zika and A. L. Jacobson 2005).
Frequently planted cultivars of Aucuba japonica with dark green and yellow variegated leaves are var. variegata Dombrain.
