Astrophytum myriostigma - Bishop's Cap

Astrophytum myriostigma is a collectible cactus with an elegant and easily recognizable appearance, valued for its geometric shape, well-defined ribs, and surface covered with numerous fine white dots. Unlike many other cacti, this species is naturally spineless, giving it a clean, sculptural, and highly decorative appearance.

As it matures, the plant retains its compact silhouette and may produce large, highly attractive yellow flowers. It is an excellent choice for cactus collections, bright shelves, or minimalist arrangements.
