Name: Paul Utah (Zone 5b) Grandchildren are my greatest joy.
I had looked at this "ugly" little cactus at a favorite nursery for several months but never bought it. A few days ago when I went there it was ready to bloom so I brought it home.
Paul, why not post it in the ID forum. I bet you'll get an identification very quickly. It actually rings a bell with me but I can't come up with the name right now.
