So I got this little guy a 9 months ago in some grocery store clearance bin. It didn't have a name, ID, or care instructions, but it's been growing fine in my window (east facing--I live in Indiana, USA) with little watering (1 per week). The leaves are thick and stiff, so I treated it like I treated my succulents (RIP), which fared worse, ironically. The largest leaves are 1.25 inches. It is 3.5 tall and 5 inches in diameter. Please help me ID it so I can make sure it stays healthy and because I'd like to combine it with some other plants of similar care requirements. Thanks!
