What is this plant called?

I gave my wife an 'all three are correct' plant a few Christmases ago. It's still alive, which is an achievement for her, although it has never flowered.

I just saw the nane I knew it as and didn't read the others got caught out shucks.

I've only ever known this as a chain cactus

I picked ‘All Three are Correct’ because that’s what they’re called besides Zygocactus.

Player #8665273, that is what we call them in NZ and in Australia.

Also known as inch plant

luckycatfay, our answer is still correct in my opinion.

I picked Christmas cactus lol that's a very good trick question 😂

Actually, that's what is most commonly known as the Easter Cactus. The Christmas and Thanksgiving cactuses have leaves which are more angular and rectangular in shape, with better defined corners to the segments, which are spikier.

Is it also known as a Zygo cactus?

I use to have several of them!!
