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.

i got this plant as a birthday present last year and i’m absolutely in love with her. she’s struggled with a little bit of browning but after maintaining a skilled watering schedule she is doing just fine. thrives even in low light conditions which is perfect for me!

My second go around with this plant and I love it so much. Can survive pretty much anything. My first plant survived my cats terrorizing it and only died when my mom forgot I had it in my room.
