🌱 Morphology
   With a diameter of over 20 cm.... Solitary, globose to short-cylindrical cactus without spines, which can exceed 50 cm in height with age. It generally has 5 very pronounced ribs, although specimens with 3 to 7 may appear, which can increase with age. The epidermis is green, grey-green, or silvery and is covered by numerous small white trichomes that form a characteristic speckled appearance. The areoles are circular, woolly, and completely lack spines. The profile of the ribs viewed from above resembles a bishop's miter, the origin of one of its common names.

🌍 Distribution, habitat and family
Native to the arid and semi-arid regions of central and northeastern Mexico, mainly in San Luis Potosí, Nuevo León, and Tamaulipas. It grows in mountainous areas and open slopes, frequently on limestone soils, among xerophilous scrub and desert vegetation, at approximately 750 to 1,500 m above sea level. It belongs to the Cactaceae family.

❄️ Temperature — USDA Zone 9a
Tolerates minimum temperatures of up to −7 ºC if kept completely dry and properly acclimated. During winter, it is recommended to keep it dormant and the substrate dry.

☀️ Lighting
Needs very intense light during active growth and tolerates direct sun. A target of approximately 18–25 mol/m²/day PAR DLI promotes compact growth and good expression of the epidermis and white trichomes.

💧 Growth cycle and watering
Winter dormancy. Its growth is concentrated mainly during spring, summer, and early autumn. During the active period, it is recommended to water abundantly and let the substrate dry out completely before the next watering. In winter, it should be kept practically dry, especially when temperatures are low. The substrate must have fast drainage to prevent moisture accumulation around the roots.

🌸 Flowering
Produces large, fragrant flowers, about 4–7 cm in diameter, in bright yellow, occasionally with orange or reddish tones at the base. They appear on the areoles near the apex during the warm season. In Madrid, flowering begins between May and July, but it can re-flower and produce flowers throughout the season.

🌿 Nutrition
During the active growth period, a fertilizer with a high content of assimilable calcium and low nitrogen levels is recommended, such as Desert CHOICE® Cactaceae, 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 technological square pot and with the substrate activated with mycorrhizal fungi.
