🌱 Morphology
Cactus with globose to cylindrical stems, generally solitary when young and capable of forming small clusters with age. The stems, grayish-green to bluish-green and occasionally with reddish or purplish tones, reach approximately 10–20 cm in height and 7–9 cm in diameter, although they can grow larger. It has 5–11 low, wide, and rounded, slightly sinuous ribs. The areoles are small and somewhat woolly. The most striking feature is its sparse spination: the central spines may be absent or appear in small numbers and be very short, while the radial ones may also be missing.

🌍 Distribution, habitat, and family
Northern Mexico: Sonora, Sinaloa, southwestern Chihuahua, and Durango, at approximately 200 to 1300 m altitude. It grows in clearings and rocky slopes of tropical deciduous forests and oak forests, on sandy-silty soils and igneous rocks. It belongs to the Cactaceae family.

❄️ Temperature — USDA Zone 10a–11b
It tolerates minimum temperatures down to −2 ºC. It is a species that is not very resistant to frost and must be kept completely dry during cold spells. The cultivation sources consulted agree on placing its tolerance at around −2 ºC.

☀️ Lighting
During active growth, it requires high lighting, with an approximate goal of 18–25 mol/m²/day of DLI PAR. Although it needs good light, its delicate epidermis and reduced spination make it advisable to avoid sudden exposure to intense sun, especially for specimens acclimated to shade conditions. It can be grown in soft direct sun or intense filtered light.

💧 Growth cycle and watering
Winter rest. During winter, it must be kept completely dry and protected from frost. Growth is concentrated mainly from spring to summer. During this period, abundant watering is recommended, allowing the substrate to dry out completely before watering again. It requires excellent drainage, as it has a tendency to rot when it remains damp during dormancy.

🌸 Flowering
It produces large, fragrant, bell-shaped or broadly funnel-shaped flowers of an intense bright yellow, which can reach approximately 7–10 cm in length and up to 10 cm in diameter. They appear near the apex and stand out extraordinarily against the practically spineless body. In Madrid, flowering can be expected mainly between May and July.

🌿 Nutrition
During the active growth period, a fertilizer with a high content of assimilable calcium and low levels of nitrogen, such as Desert CHOICE® Cactaceae, is recommended, applied once a month when watering. Before flowering, it can be supplemented with Desert CHOICE® Flowering.

This is an inimitable xerophyte grown in Madrid in a high-tech square pot with substrate activated by mycorrhizal fungi and biofungicides.
