🌱 Morphology
   Solitary, globose to slightly ovoid cactus, about 5–6 cm in diameter, with a matte green epidermis and a slightly woolly apex. The tubercles are conical, initially prominent and later flattened, arranged in a spiral and provided with a longitudinal groove. Striking red nectary glands appear in these grooves, which produce nectar and attract ants. The areoles develop 20–24 white or grayish radial spines, flexible and with a darker tip, in addition to 1–3 more robust central spines, reddish, brown or corneum.

🌍 Distribution, habitat and family
Endemic to northeastern Mexico, mainly San Luis Potosí and neighboring areas of Guanajuato and Nuevo León, where it grows at approximately 1800 to 2350 m, on limestone slopes, stony ground, dry grasslands and clearings in scrubland or open forest. It belongs to the Cactaceae family, Cactoideae subfamily, Cacteae tribe. The nomenclature follows Joël Lodé, Taxonomy of the Cactaceae (2026), volumes III–VI.

❄️ Temperature · USDA Zone 9a
Tolerates minimum temperatures of up to −7 ºC in dry and well-acclimatized specimens. During winter it must be kept completely dry.

☀️ Lighting
It needs very intense lighting and direct sun to develop compact spines and promote flowering. As a guideline during active growth, a PAR DLI of 20–30 mol·m⁻²·day⁻¹ is recommended.

💧 Growth cycle and watering
Winter dormancy. During spring and summer, abundant watering is recommended, allowing the substrate to dry out completely before the next watering. From autumn, watering is gradually reduced until it is kept dry during winter. Excellent ventilation helps prevent problems caused by excess moisture; the nectar from the glands can promote the appearance of fungi on the epidermis if it accumulates.

🌸 Flowering
The flowers appear at the apex and are large in relation to the size of the plant, lemon yellow to bright yellow, fragrant, funnel-shaped, and about 5–6 cm in length and diameter. The outer parts may show a characteristic greenish or slightly pinkish central band. Flowering can last from spring to autumn depending on growing conditions.

🌿 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® Cactáceas, applied once a month when watering. Before flowering, it can be supplemented with Desert CHOICE® Floración.

This is an inimitable xerophyte grown in Madrid in a technological square pot and with the substrate activated with mycorrhizal fungi and biofungicides.
