5-7cm Astrophytum myriostigma（Big one）

Propagated from premium lineage and grown to maturity, this impressive cactus features a robust globular to columnar body, measuring 5-7cm in diameter—ideal for standalone displays, cactus gardens, or collector showcases. At this mature size, it flaunts the iconic "Bishop's Cap" traits elevated by its multi-rib design: a sharp star-shaped cross-section defined by 6-8 (or more) prominent, angular ribs that create a bold, geometric silhouette. Its epidermis exhibits a rich, deep green hue with the species' characteristic smooth texture, highlighting the well-developed ribs and giving it a sculptural, sophisticated appearance. Each large-sized specimen is healthy, well-established, and showcases the full charm of a mature multi-rib鸾凤玉.
