🌱 Morphology
It looks like a candelabra sculpted in green, cream, and yellow marble, as if a large plant column had been hand-painted before beginning to branch out. Its blue-green stems are crossed by deeply wavy ribs, and the variegation draws irregular patches and bands over them, making each specimen have a different pattern. It is a plant of monumental appearance even when it is still young.

It is a succulent shrub or small tree, highly branched with age, with generally thick, quadrangular stems, with markedly wavy ribs and margins provided with small tubercles. On them appear pairs of spines short and robust, associated with small triangular shields. The leaves are rudimentary and deciduous, appearing mainly at the growth tips. Like other Euphorbia, it produces irritating white latex.

The variegation is due to the presence of tissues with different capacities to produce chlorophyll, so green areas appear combined with cream, white, or yellowish areas. Highly variegated specimens usually grow more slowly.

A feature especially useful for differentiating it from Euphorbia ingens is precisely the shape of the ribs: in E. ammak they are clearly wavy, while in E. ingens they are usually straighter. There are also differences in the shields where the spines grow and in the plant's adult architecture. For this reason, many specimens marketed as E. ingens ‘Variegata’ or E. ingens ‘Marmorata’ actually correspond to E. ammak ‘Variegata’.

🌍 Distribution, habitat, and family
Euphorbia ammak is native to western Saudi Arabia and northern Yemen, where it grows in desert areas and dry scrublands. It belongs to the Euphorbiaceae family.

❄️ Temperature — USDA Zone 10a
It tolerates minimum temperatures of up to −1 ºC for short periods, provided the plant is dry, acclimated, and protected from prolonged frosts. It is especially sensitive to the combination of cold and humidity.

☀️ Lighting
During active growth, it needs very high lighting, with a target of approximately 18–25 mol/m²/day of PAR DLI. It tolerates and appreciates direct sun after gradual acclimation. In highly variegated specimens, it is advisable to avoid sudden changes to intense sun, as tissues with little chlorophyll are more sensitive to burns.

💧 Growth cycle and watering
Winter dormancy. During the active period, it is recommended to water abundantly and let the substrate dry out completely before watering again. In winter, watering is significantly reduced, keeping the substrate practically dry during cold periods.

🌸 Flowering
It produces small yellowish or yellow-green cyathes, which are not very striking compared to the spectacular stems. In Mediterranean cultivation, flowering may concentrate during spring.

🌿 Nutrition
During the active growth period, a fertilizer specific to succulents is recommended, with a high content of assimilable calcium, such as Desert CHOICE® Succulents, applied once a month when watering.
