It's a small slow growing spherical cactus, which is very popular among green collectors. The peculiarity of this plant is its beautiful short spines, arranged in a corolla, more golden towards the center and tinged with white at the tips. The areoles are covered with a thick white down which, together with the spines, completely covers the cactus. Usually it tends to bunch up, as it grows, forming a thick shiny cushion. During the winter, small flowers, ranging in color from white to cream, emerge from the dense feathery mantle.
