Description: The yellow appearance of this Echinocactus horizonthaloniusSN|1711]]SN|1711]] is caused by an aberration called "schizochromism". Here, though, the specific green pigment (chlorophyll) is missing: every other pigment is present at normal levels, the dominant green colouration is lost, but will still more than likely have normal other pigments that give the yellow overall appearance of stems and the red colouration of spines.

Subspecies, varieties, forms and cultivars of plants belonging to the Echinocactus horizonthalonius group

Echinocactus horizonthalonius Lem.: It is a relatively small barrel cactus that normally grows unbranched. The body of this plant is a chalky blue colour, and some forms have magnificent spines.
Echinocactus horizonthalonius var. minimus: even very small plants are able to flower. Distribution: Cedral towards Esacion Vanegas, San Luis Potosi, Mexico.
Echinocactus horizonthalonius f. montruosa hort.
Echinocactus horizonthalonius subs. nicholii (L.D.Benson) Doweld: Stem eight- ribbed, pale grey-green to bright blue-green, up to 50 cm tall and 20 cm across. Distribution: Sierra del Viejo, Sonora (Mexico) and Pinal County, Arizona (USA).
Echinocactus horizonthalonius var. subikii Stanik & Dráb: is a rare, very stunted, bluish frosted and pure white Flowering form. Distribution: Ejido Soledad, Nuevo León, Mexico
Echinocactus horizonthalonius cv. Albinous (Yellow form) hort.: ( Chlorophylless form) Stem with a bright yellow overall appearance and grey/red contrasting spines.
Echinocactus horizonthalonius cv. Sirotoge Suiheimaru hort.: Short spined mutant selected in Japan.

Notes: Albinism is a genetic aberration where there is a total absence of pigments. An "albino" plant therefore is one with no pigment whatsoever, it will have totally white stems or leaves.
The yellow appearance of this Echinocactus is more precisely caused by another aberration called "schizochromism". Here, though, the specific green pigment (chlorophyll) is missing: every other pigment is present at normal levels, the dominant green colouration is lost, but will still more than likely have normal other pigments that give the yellow overall appearance of stems and the red colouration of spines.

Cultivation and Propagation: Variegated and albinous cacti are regarded as choice and difficult in cultivation, but despite that many of them are relatively easy to grow. But be aware that they cannot tolerate prolonged exposure to direct sun light (especially during the hottest summer days), so grow them in half-shade or under filtered sun. The the albinos can survive only if grafted on a strong green base.
Use mineral well-permeable substratum with little organic matter (peat, humus). Water sparingly from March till October and keep perfectly dry in winter at temperatures from 5 to 15 degrees centigrade. (In general these plants are more tender and cannot endure freezing temperatures ) In the rest period no high atmospheric humidity!!
Propagation: Plants are grafted onto column-shaped cacti.
