🌱 Morphology
It looks like a small sculpture carved from ivory and green, as if an ear of corn had grown in the middle of the desert and someone had painted its ribs cream. The variegation makes each specimen unique: the areas with less chlorophyll can run along the stems, forming white, yellow, pink, or even reddish patterns that change in intensity with the light, temperature, and the plant's condition.

It forms a succulent clump, generally compact and densely branched, with upright stems ranging from pale green to whitish, marked by 7–10 very pronounced ribs. The tubercles, arranged in vertical rows, give it its characteristic ear-of-corn appearance. The stems can reach approximately 15–30 cm in height and about 1.2–4 cm in thickness. The leaves are very small, narrow, and short-lived; they appear at the growing tips and soon fall off. Small spines develop between the tubercles, corresponding to hardened, modified floral structures that can reach around 2 cm. Like all Euphorbia species, it produces white latex when injured. The variegated form has areas with reduced chlorophyll, so it must be protected from excessively harsh sun exposure.

🌍 Distribution, habitat, and family
The taxon is related to Euphorbia mammillaris, a species endemic to South Africa, distributed between Albertinia and Grahamstown in the Eastern Cape and Western Cape provinces. It grows on plains and rocky slopes, among scrubland and on alluvial deposits or schist soils, within Fynbos and Cape scrub environments. It belongs to the Euphorbiaceae family. SANBI considers Euphorbia submammillaris a synonym of Euphorbia mammillaris, and Kew also treats E. mammillaris var. submammillaris as a synonym of E. mammillaris.

❄️ Temperature — USDA Zone 9b
It tolerates minimum temperatures of up to −4 ºC if kept completely dry, properly acclimated, and exposed to cold for only a short time. For the variegated form, it is especially advisable to avoid the combination of low temperatures, humidity, and tissues with little chlorophyll.

☀️ Lighting
During active growth, it needs intense light, with a target of approximately 18–25 mol/m²/day of DLI PAR. The variegated form requires gradual acclimation to direct sunlight: exposure that is too sudden can cause damage to the areas with less chlorophyll. High but well-adapted lighting helps keep the stems compact and enhances the expression of its cream, yellow, and pink tones.

💧 Growth cycle and watering
Winter dormancy.
During the active period, regular watering is recommended, allowing the substrate to dry out completely before watering again. In winter, it should be kept practically dry, especially when temperatures are low. Rapid drainage is essential to prevent root problems.

🌸 Flowering
It produces small cyathia at the ends of the stems, generally reddish in color, which may appear during the growing season. In its natural area, Euphorbia mammillaris flowers mainly between May and October; in Madrid, it may flower during the warm months, especially from late spring through summer.

🌿 Nutrition
During the active growing season, a fertilizer specifically designed for succulents is recommended, with a high content of assimilable calcium, such as Desert CHOICE® Suculentas, applied once a month when watering.

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