Led by the fluffy white superstar known as Old Lady Cactus, Mammillaria is the idol group of the cactus world. Cute, compact, and endlessly collectible. But do not let the charm fool you—this genus includes more than 400 species, from tiny globes to columns, from beginner favorites to ultra-rare collector trophies. The name comes from the Latin mamilla, meaning “nipple,” referring to the prominent tubercles hidden beneath all those spines.
