It’s a cactus! Super easy to care for. I’ve moved it to a pot with another cactus and succulent and it seems to be doing well. I just let them hang out on my windowsill and do their thing. Nice, easy plant to have around.

love my moon cactus, they look so cool and THEY’RE RED!! I love red. super easy to take care of because it’s a cactus so it doesn’t need a ton of attention and only needs to be watered occasionally but they do tend to die kind of quickly. with my first one, the cactus drank up all the water wayyy too quickly and the red bulb at the top filled with water and it ended up dying after about 7 months. my new one has survived a good six months so far but the bottom that is partially in the soil is starting to wilt. it’s limp and brown but i’m hoping some good old tlc will revive it.

The colorful part and the green part are actually two separate cacti! The colorful one can’t produce chlorophyll, so it’s grafted to the bottom one! It’s actually parasitic, but if the bottom cactus begins to show signs of dying, the top can be removed and re-grafted to a different host to save both cacti!

This moon cactus is fairly new to me, so far she is a survivor. I have always wanted one so I ended up getting her for hardly anything. I think I paid $1.75 since Krogers had their plants on sale for 50% off.

these plants are kind of doomed to live a short life just because of the nature of the plant(s)
pretty to look at but would definitely not recommend for beginners
