New little friend, wildly overpriced for Xmas but I had to have it because it's so #pentagonal but while I'm noting this @teamgardentags -- this is a Sider Cactus, not a Spider Cactus. If you compare the owners of the two common names on Google Images you'll see this is a Sider!
Aw, you're adorable! 🥰 I said you shouldn't deface your adorable baby on my account, though! It's practically impossible to root a cactus in the winter anyways, so it's for the best. Man, idk why the grocery stores here have such weak floral depts! I've never so much as seen a grocery store cactus. 🙄
