Astrophytum myriostigma Onzuka Quadricostatum

Astrophytum myriostigma Onzuka Quadricostatum is an exceptionally rare four-ribbed cultivar of the Bishop's Cap cactus, representing one of the most sought-after forms in the Astrophytum world. The 'Onzuka' lineage is renowned for producing specimens with perfect symmetry and enhanced white flocking that creates a stunning contrast against the green body. This quadricostatum variety features exactly four ribs instead of the typical five, giving it a distinctive square-like appearance when viewed from above. The dense white dots covering its surface create an almost frosted appearance, making each specimen a living work of art. Slow-growing and highly collectible, this cultivar produces beautiful yellow flowers and represents the finest in Japanese Astrophytum breeding.
