Description: This is a free offsetting small form of E. grusonii that is covered by yellowhish-white wool with short yellow spines. The rib structure is not yet apparent, and they have pronounced tubercles making them look superficially like Mammillarias. With age they will form large crowded clumps.
Cultivation: Frost tender but cold hardiness increases with improved drainage, so keep plants as dry as possible in winter. Provide the plant with extremely well-drained soils, as plants are subject to crown and soft rot if they remain too moist. They grow best in full sun or half shade, which will help to maintain the lustre of the spines and plants compact. They are prone to mealy bug and red spider mite.
Propagation: From cuttings (but it is difficult to grow this plant on its own roots) or preferably by grafting.
