My one and only house plant. A cactus that I have had for 25 or 30 years. I water it once a month whether it needs it or not. And every couple of weeks I rotate it 180° as it grows towards the light and would just fall over if I didn’t. When it was about 10 it grew a buddy, but it only lasted about five or 10 years and now it is alone again. You can see its remnants on the left at its base.
Would you like to add your own plant?
