An outstanding species with a robust globular body and powerful, curved spines in shades from dark brown to jet black. Juvenile plants show lighter tones—yellow to brown—that gradually darken as the plant matures.

An outstanding Eriosyce, characterized by strong, recurved spines ranging from dark brown to black. Extremely rare and highly distinctive. Propagation is by seed only, a process complicated by the low availability of viable seeds. Seedlings are very sensitive and intolerant to excess moisture; overwatering is the main cause of loss at an early stage. Suitable only for experienced growers.

Upon arrival, allow at least 2 weeks before replanting to ensure roots are completely dry. This practice significantly reduces the risk of rot after the first watering. Cultivation requires a highly mineral, fast-draining substrate, full sun exposure, and minimal irrigation. Growth is slow, and each increment represents a significant achievement. Recommended for collectors who appreciate rare and challenging taxa.
