This charming miniature has long been popular for its free-flowering nature and ease of cultivation. Heads average about an inch in diameter and offset to form dense mats belying the taproots that comprise the bulk of this cactus “iceberg”. Therefore, a not-too-shallow pot is recommended. The clone offered here has more open spination than most cultivated forms, exposing the gray-green epidermis of the tuberculate stems. The naked-scaled flower buds (lacking hairs or spines) are typical of the genus and open to delicate pink flowers as large as the individual stems that produce them. We offer divisions of HBG 66375, a plant originally collected by Argentine agronomist Omar Ferrari at Las Palmas, Cordoba, Argentina. $7.
