This listing is for one pup from a Thimble Cactus (Mammillaria gracilis fragilis). These pups are not yet rooted. There are two sizes of pups to choose from: large pups are approximately 2.5 cm tall (1") and small pups are approximately 1 cm tall (3/8").
Thimble cacti grow in clusters, by producing pups from the main body of the cactus. As the plant grows, it can reach a height of 10 cm (4"), and will have 1 or more brown spines in addition to the white spines. Mature plants may produce light yellow flowers.
