Help ID this cactus!
This little guy was the first cactus we ever purchased. Being new to the AZ and new to gardening, we didn't do a great job getting his common or scientific name. We bought him at Desert Winds nursery and at the time he was just 2 stalks. A year later, he has 5 new stalks branching from his base and the top of one of the main stalks is splitting into multiple branches. Recognize him?
