I would imagine you'd be able to cross pollinate two Gymnos, but I don't know a lot about cross-pollinating cacti.

The moon cacti you see in the stores are unnatural (yellow, orange, red, pink). They are man made and unable to produce their own chlorophyl (plant food), hence being grafted to a green stalk. If you're lucky, sometimes you find a purple one that isn't man made grafted and you can remove it from the stalk and root it (you can't do this with the others, they won't survive). I'm not sure what species of Gymno the purple ones are, I think G. mihanovichii (but not sure which cultivar).

But the original green moon cactus? I didn't know there was one, but then again, I'm no expert on Gymnos. Where did you read about the original one? I am just curious as you've got me interested now.

I've got the purple one I wanted to cross it with original green form or neon form the babies then will be green/purple/color mix and able to survive on their own roots. im sure my purple is G mihanovichii as its flower are neon pink. Here are photos of the original green of these.
