What's the purpose of grafting? Does it actually benefits

I may be mistaken, but those colored ones may be lacking chlorophyll, and are aided by the graft.

This is just from vague memory, I may be wrong. Not all plants are green and do fine ungrafted, so yet again I may be wrong.

Also, I'm not a fan of those particular "plants" They don't do great and they're just a step away from hot glued fake flowers on cacti to make them look pretty.... or GMO fluorescent fish.... or neon spray painted succulents with glitter on them.

Also, my hardware store sells succulents with a fully glued top layer of gravel which makes me go pic related.

But if you want to discuss grafting in general, yeah, it's common and useful for a variety of reasons. A good/fun skill to learn too.

Oh, and genetic transfer can occur at graph sites. So it can be used to create new species if you culture the cells affected at the graph site. It was recently demonstrated with two different species of tobacco.

Pretty exciting if you want to do some very sterile lab work.

It's used to grow trees without seeds, lots of oranges grown in Florida wouldn't be possible without grafting. Not sure if it works like that with every seedless plant, but many depend on them.

It's common for varieties that make good fruit to also have shitty root systems or vice versa. Take the shoot from a good producer and graft it to the roots of a good root system and you get the best of both worlds

For cactuses it's almost exclusively decorative.

you know, in a way it could benefit the plant - by being attractive, more people are likely to propagate it, thus increasing their numbers. but then, it's all about us really, isn't it? :/
