Astrophytum Myriostigma

✅ Astrophytum myriostigma – The Star of the Desert
The Astrophytum myriostigma, known as the Bishop’s Cap Cactus, is a geometric marvel from the high deserts of northeastern Mexico. Its striking, perfectly symmetrical, ribbed body is cloaked in a delicate layer of white, star-like flecks, giving it a celestial, sculptural elegance. This spineless cactus captivates with its clean, architectural form, making it as much a piece of living art as a plant. In spring, it surprises with silky yellow blooms that contrast beautifully against its silvery-green skin.
