Do you mean what some call pencil cactus? If so, I have this one that I never cared for, but haven't made myself just dump it. It needs TLC, but you can have it for postage if you want it. There are actually two: one green and one red. Here's a picture:

That's weird, I know I responded to this post, but now it's not here.

Dave, if you mean pencil cactus, I have this one I have not cared for, because I really don't like cactus. I keep waiting for it to die so I can throw it away, but it hangs on! If you want it, just pay postage. Give it TLC and it will bounce back. There are two plants: one that grows green and one grows red.

Firestick and pencil cactus are 2 different plants. Firestick turns red all over not just on tips.

I would like to have a firestick too. Bought a plant one time that was listed as firestick and it was a pencil cactus.

We call it pencil cactus, although it's referred to as pencil tree.
