Schmid (1991) described groups of plants that have the same basic structure and vary only in their leaf color. The cultivars listed are very similar to each other and some are probably identical i.e. the same plant but with a different name.

This group was defined as "Yellow-margined forms similar to H. 'Tokudama Flavocircinalis' arise in cultivation and tissue culture and are sufficiently different to be given cultivar names. All of them belong in a broad sense to a group of yellow-margined mutants here called the H. 'Tokudama Flavocircinalis' group. This group includes mutants having lavender, not white flowers, and less cupped and rugose leaves."
