As a seller with actual named plants I imagine it's a huge worry when tags are lost. Mine are all the "Heinz 57" variety of holiday cactus, I don't have any special cultivars. I know there are many named hybrids on the market but I've never seen the big box stores carry actual named varieties. I think a lot of the nurseries mass produce them from cuttings for the holiday trade. I know there are many serious collectors who want only named cultivars but lots of folks purchase them for the color that happens to catch their eye and don't worry about whether they are named or not. A lot of folks purchase them from the big box stores for temporary holiday decoration just like with Poinsettias and Cyclamen.
