This heading actually is for the 'lutea' version of the Peanut Cactus, which is an 'albino' form of the 'normal' plant. Unfortunately, there was no heading for the 'normal' plant so everyone else seems to have uploaded their photos to this plant, and all of the photos here are in the wrong place, except for the ones of the obviously pale yellow cacti. This plant is usually grown grafted, and is a pretty wimpy alter ego of the otherwise hardy version of this cactus. I have not seen a 'lutea' bloom, but wouldn't be surprised, if the graft was healthy, and it was well protected and fed, that it could manage it. Sold mostly as a curiosity. I personally have not had any luck keeping one of these alive for a long time, but I keep all my plants outdoors in the environment, and this form seems a bit too wimpy for that abuse.

Have owned and known this plant by Chamacereus silvestri, or peanut cactus. Have had one every since I was a kid, is a small miniature cactus growing less than 3 inches. Blooms are bright scarlet red that are about 3-4 inches in size. It is a dependable bloomer, usually in the Spring to early Summer. Easy to propagate, it is covered with short spiny needles that easily stick to anything that it touches or touches it. These small sections will root rapidly with no assistance. Just let them lay on the soil and you have a new start.
This plant has been said to grow in the following regions:
Phoenix, Arizona , California Castro Valley, California Clayton, California Clovis, California Fair Oaks, California Manhattan Beach, California Muscoy, California Oak View, California Henderson, Nevada Monterey, Tennessee El Paso, Texas Edgewood, Washington
