can somebody please identify my cactus cuttings?

hey guys,
i got a few cuttings off my friend, im thinking it may be a peruvian torch but the ribs on it are really thin in some places.
if somebody could help me identy it i would appreciate it.

It looks like the plant known as Cereus peruvianus, but the taxonomy of that genus is really confused. It's an old name applied to a species not from Peru.

Once they start growing and mature you should end up with huge floral displays throughout the warmer months. It's self infertile but if you can get a pollinator then you might get fruit, similar to a dragonfruit but smaller and without the leafy appendages.

thanks for the help, i really apreciate it.

You're welcome, but just to be safe this ID is not absolute. As I said it's a really confusing genus. But this is most likely the species.
It's so easy to grow that mine doesn't grow very much at all. Instead it puts nearly all of its energy into flowers that will never make seeds because I don't have a cross pollinator.

oh true, at least you would have nice flowers constantly
once mine roots im going to use it as grafting stock and ill chuck a few of my peyote babies onto it to give them a bit of a boost..
do you know if they are good to use as a grafting collum?

I've never seen anyone use it for grafting so I can't comment on how good it might be. But it is strong, fast growing (when it decides to grow) and rather inexpensive as well as being easy to propagate. These all point to being a potentially good stock but this is all speculation.
The small vascular bundle might end up being advantageous for grafting smaller scions onto it, but again, this is all speculation.

thanks for your opinion, i was roughly thinking the same.
i guess ill just have to try it out and see how it goes, ill post up a topic once i start to let everybody know if it works well as grafting stock.
