female. Not variegated.
A. japonica 'Nana', a compact form to about
3 ft., relatively erect, with abundant fruit on
female plants. Not variegated.
A. japonica crotonifoloa,
'Spotted Laurel,' a lovely variegated form, is a
female plant with bright yellow splashed leathery
leaves.

extremely shade tolerant. It is slow growing and
sometimes can revert back to
