It’s a very resilient plant that can handle being mistreated again & again. Once given the proper love, it can become quite huge. A lot of people dislike how long their arms get, I find them cute.

He’s still a little small so every time he grows a new arm it starts to weigh him down so you have to check they’re upright. ❤️❤️

Honestly there’s not much to say about this one, easy to care for, water once a week maybe even less but don’t be fooled about his apprentice he may look cute and fluffy but he’s actually a pointy demon - you have been warned 🤝
