This 3-inch, pink and magenta bloom surprised your guest contributor  (Sentient Meat) this week, a shining beacon from the patio rooftop where  it was living with a few other sun-soaked and rather neglected cacti  and succulents. (Los Angeles has been hot for a couple weeks and the plants on this roof are all looking a bit worse from the relentless exposure.)
The bud had gone overlooked, but it was impossible to  overlook this flower. This is the first time I've seen this cactus in  bloom. It was purchased without a label, but I believe it's Coryphantha elephantidens. I love the color gradient from light pink at the edge the petals to deep magenta at the center tips.
