This is a great cactus for those who are afraid of cacti because of the sharp spines and glochids. Astrophytum, means "star plant" in Greek. A. myriostigma is commonly called Bishop's Cap. The cactus is completely spine-free, and the skin is covered with white flecks that act as a sunscreen.
Bishop's Cap would be a perfect cactus for kids to learn about cacti and succulents. However, the cactus has to be about five to six years old before it flowers, so if you're interested in the flowers, be sure to buy a larger one.
