aaahaha. Yeah, and they also sell unicorn trees.

What an unjustly sarcastic response. Why bother posting that negativity?

The "moon cacti" or bright orange/pink/etc colored cacti (Gymnocalycium mihanovichii) that they sell for real cheap in stores are all grafted to Hylocereus (dragon fruit). You can cut the scion from the stock and let the Hylocereus grow out just fine. They may, however, have bred those Hylocereus to be good for grafting and not much else - you'd have to grow them to maturity to see if they are going to be any good for fruit or not.

The good news is if you're interested in grafting cacti the moon cacti can be had for cheap and will grow you many usable stocks :)

Oh, sorry. I wasn't being negative. I truly didn't realize that dragon fruit came from a cactus. I thought it was an April fools joke. Check the date.

Ah well then I rescind my harsh comment :)

Thank you euphony for the info. That helps alot. I guess I'll just stick with the cuttings from known varieties lol
