🌱 Morphology
Japanese cultivar of Astrophytum myriostigma, with a solitary, globose to short-cylindrical body and generally 5 ribs. It is characterized by combining the spectacular white spotting and epidermal patterns of ‘Onzuka’ with the prominent, pointed tubercles that interrupt the margins of the ribs, characteristic of ‘Kikko’. The areoles stand out between deep transverse grooves, creating a geometric relief reminiscent of a turtle shell. It is spineless. The quantity, distribution, and pattern of the white trichomes can vary considerably between specimens.

🌍 Distribution, habitat, and family
Japanese horticultural cultivar, obtained through selection and greenhouse cultivation; it does not correspond to an independent natural population. Its parent species, Astrophytum myriostigma, is native to the arid and semi-arid regions of central and northeastern Mexico, where it grows mainly on stony and calcareous soils, among xerophytic scrubland. It belongs to the Cactaceae family.

❄️ Temperature — USDA Zone 9a
Tolerates minimum temperatures down 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 several hours of direct sun once acclimated. An approximate target of 18–25 mol/m²/day PAR DLI promotes compact growth and allows for the proper development of both the tubercle relief and the characteristic white patterns of ‘Onzuka’.

💧 Growth cycle and watering
Winter dormancy. Its growth is concentrated mainly from spring to early autumn. During the active period, it is recommended to water abundantly and allow the substrate to dry out completely before the next watering. In winter, it should be kept practically dry, especially at low temperatures. The substrate must provide rapid drainage and prevent moisture from lingering around the roots.

🌸 Flowering
The flowers are similar to those of Astrophytum myriostigma, pale and bright yellow, and appear in the apical area during the warm season. In Madrid, flowering occurs mainly between May and July.

🌿 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 cultivated in Madrid in a high-tech square pot and with a substrate activated with mycorrhizal fungi and biofungicides.
