Mammillaria compressa

Mammillaria compressa is a spherical cactus, that develops a quite "massive" cylindrical shape, as club-shaped tubercles proliferate. Its tubercles, between which there is a thick down, are very pronounced, close together and firm (hence the name ‘compressa’). Its spines, which vary in color from chalk white to brown, are very small and short. In winter and spring, it blooms with small bell-shaped flowers, which vary in color from purplish pink to deep red, embedded in its down.
