Orwell finally passed on and so did one of his pups. The one that did make it was potted in a small pot and is being kept under a bright light. I named her “Nova”. #CactusClique #HappyPlants #PlantsMakePeopleHappy #PlantAddict #PlantTherapy #TexasGregGang #CentralTexasGang #SanAntonioGregGang

I’ve had this about a month. Didn’t know much about it when I bought it. Is it supposed to get big or stay this small? Are they slow growers? Does it look like I’m doing anything wrong from the photo? Thanks! #Euphorbia
