I grow Zippelianum, Medium and Humile
This one is a green form of Medium
a silver form of medium, they rarely show fenestration, most of time only splits
a Humile, it has perfectly heart-shape thick and glossy leaves, no split, no holes
There are variegated form circulated in the market of Zippelianum and Medium (both silver and green form), but too expensive now for me... need to be patient for now
