Description: Echinocereus ferreirianusSN|21825]]SN|21825]] subs. lindsayi f. monstruosus is a free offsetting small form of Echinocereus ferreirianusSN|21825]]SN|21825]] subs. Lindsayi that forms large, proliferating stems, with white woolly areoles and short bristle-like spines. The rib structure is not yet apparent, and it has short tubercles making it looks superficially like Mammillarias. With age it will form large crowded clumps.
Habit: It shows an abnormal uncoordinated form of vegetative growth, with a multitude of condensed lateral proliferation, each areole gives origin to a new stem only a 1-2 centimeters across, and the plant looks more like a strange furry animal or a marine creature than a cactus.
Flowers: Very showy but seldom seen in cultivation, pink, often failing to open widely, with pericarpel and floral tube densely covered by white woolly areoles.

Cultivation and Propagation: 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.
Frost Tolerance: Light frost protection required for safe cultivation, but can tolerate sporadic light frost.
Diseases and pests: Watch for infestations of mealybug, scale insects and spider mite.
Propagation: From cuttings (but it is very difficult to grow this plant on its own roots) or preferably by grafting.
