Kokkou Daruma Ardisia. This species, Ardisia crispa, is a zone 7 Ardisia. It is much more cold hardy than Ardisia crenata or Ardisia japonica. It makes a small shrub of 24-30 inches. The Japanese have hundreds of varieties of this species which they grow and display in the Koten engei fashion in small porcelain pots. There are shows where just this species is displayed with all of its forms, variegated and/or contorted leaves, various colored berries, etc. I purchased this cultivar for several hundred dollars some years ago in Japan. It has wavy leaves with variable white margins and brilliant red berries. At Christmas, we use this parent plant in our office for holiday cheer. It is truly incredible. The most remarkable thing is that it comes true from seed with the wavy leaves and variegated margins. This is a true collector plant. That's why it ain't cheap. I have never seen this cultivar offered in America before. Limited supply.
