I'm wondering about that little appendage that’s coming out, what’s that and what’s it doing? Seems to be going away from the light.
I tried to google but most result for my searches were just offers to buy a new cactus
I have no idea, bought it because the fruit / flower looked interesting. It’s probably a dragon fruit, judging from the other comments, the fruit looked similar. It came in this pot and I water when I notice that the earth is dry
It's a dragonfruit. For reference, it's not like a standard cactus. Treat it more like a tropical plant. During the warmer months, they like to be watered frequently. In the winter, you might need to water it once or twice a month.
