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 "...broadly represents a group of yellow cultivars with H. 'Sieboldiana' parentage originating either as hybrids...or as sports in cultivation or tissue culture. They also result from long-term unstable aureomarginata (yellow or golden leaf margins) forms...All of them look much like H. 'Sieboldiana', and their descriptions are identical to that of the species (now cultivar) in every respect, except that this group has yellow (lutescent) leaves and is slightly smaller."
