-Echinocactus horizonthalonius is a small cactus: the grey-green to grey-blue stem is flat-topped or hemispheric and it slowly grows up to 30 cm tall. A yellow-ish wool protect the apical meristem: flowers and fruits will develope from it. The stem has usually 8 ribs and round areoles, with 8 radial spines and 1-3 central spines per areole. Pinkish flowers are produced during the blooming season, from March to May.

Use a very well draining soil. Even if the plant need full sun exposure, half shade may be recommended during the hottest hours in summer.
