“I believe that is the name, it was a green stock with a red prickley ball on the top. I recieved it in first grade and a few years later, the ball dried up. I still have it and the ball is still attached but it is dried up and yellow/brown…. Could you let me know if there is anything I could do to make my cactus less overwhelming?”
