🌵 Morphology: Globose cactus that with age can become short-cylindrical and reach about 45–50 cm in height and up to 50–60 cm in diameter. It can remain solitary or form clumps through basal branching. The stem has a characteristic bluish-green or glaucous color, due to the waxy layer covering the epidermis. It has sharp, non-tuberculate ribs, and oblong areoles very close to each other, almost conjoining. This cultivar lacks spines on its areoles.

🌍 Habitat and geographical distribution: It is an endemic species of Mexico, distributed in the states of Guanajuato, Hidalgo, Querétaro, and San Luis Potosí, within the center and northeast of the country. It grows mainly on limestone slopes and outcrops, in dry forest and xerophilous scrub areas, approximately between 550 and 2,300 m above sea level. Kew currently accepts Ferocactus glaucescens as a species. It belongs to the family Cactaceae.

❄️ USDA Zone and minimum growing temperatures: It can be placed approximately in USDA 9a–11. It is a species that tolerates low temperatures when kept completely dry. In Mediterranean cultivation, it is recommended to keep it dry during winter and it can withstand temperatures close to -4 °C under these conditions. 

☀️ PAR Illumination: It needs very high illumination to maintain its intense glaucous coloration, compact growth, and good spination development. An approximate target of 20–30 mol·m⁻²·day⁻¹ of DLI PAR is recommended during active growth. This range is a horticultural estimate, as no specific published DLI value is available for the species. Once acclimated, it perfectly tolerates full sun.

💧 Growth cycle and watering: It exhibits winter dormancy, with growth concentrated mainly during the warm months. In Madrid, it is advisable to start watering in spring, when night temperatures are stable, performing a generous watering and letting the substrate dry completely before watering again. This cycle can be maintained during summer as long as drainage is fast. From late summer, watering should be gradually reduced until suspended in autumn. During winter, it should remain completely dry.

🌸 Flowering: It produces bell-shaped flowers, approximately 1.8–3 cm long and up to 3.5 cm in diameter. They are mainly yellow, with the outer perianth segments marked by brownish or reddish tones and a yellow margin. The filaments and style are also yellow. In Spain, the Botanical Garden of Malaga records flowering mainly between June and August, so in Madrid, it can be expected during the summer, especially in adult specimens well exposed to the sun.

🌿 Nutrition: During the active growth period, Desert CHOICE® Cactáceas is recommended, with NPK (Ca-Mg) 4-4-7 (4-4) formulation: 4% N, 4% P₂O₅, 7% K₂O, 4% CaO, and 4% MgO, in addition to micronutrients. The supply of assimilable calcium, equal to nitrogen, contributes to the maintenance of turgor, while magnesium promotes the correct physiological functioning of the plant. It is recommended to apply by watering once a month from April to September, suspending fertilization during winter dormancy.

This is an inimitable xerophytic cultivated in Madrid in a technological square pot and with the specific Desert SOIL substrate activated with mycorrhizal fungi and biofungicides.
