Mammillaria spinosissima, also known as Spiny Pincushion Cactus, is a species of flowering plant in the cactus family Cactaceae. This prickly greenie is native to the central Mexican states of Guerrero and Morelos, where they grow up to 5-6 ft (1.5-2 m).
Mammillaria spinosissima is a common guest at homes and garden centers due its captivating appearance and ease in maintenance. This powerful cactus is usually grown outdoors; however, many people like to plant it in pots and keep it at home. Home-grown, potted Spiny Pincushion Cactus grows to a height of 12 in (10 cm) and is covered with red or orange spines. The spines, in turn, are covered with cream-colored hair. When summer comes, the cactus produces eye-catching purple blooms, organized in a crown around the plant's top.
