Edited post. Error brought to my attention by Hakumin.
Neofinetia Takara Nishiki is known to mutate to the considered more desirable Takara Fukurin.
FYI, the Nishiki is a Shima and the Fukurin is a marginal striped.
My plant Neof Takara Nishiki purchased years ago initially formed a Takara Fukurin offshoot and now the original mother plant is mutating itself with its newest leaves to a Takara Fukurin.
