Description:Mammillaria muehlenpfordtii is a massive globose cactus with bright carmine flowers. It is solitary when young, but each single stem begins to divide dichotomously to form two stems as it matures, this process repeats several times giving rise to small clustered groups and occasionally to large mounds with dozen of heads. Seen from above the central whorl of woolly areoles resembles a sunflower head.
Flowers: Small in a ring near the top of the cactus on previous years growth, 10-15 mm long, bright carmine to rose-red with reddish-brown outer petals.
Blooming season: Summer.
