Mammillaria geminispina, the twin spined cactus, is a species of flowering plant in the family Cactaceae, native to central Mexico.
The growth habit of M. geminispina is variable; most grow into clump-forming colonies, though some are solitary specimens, while others still have only very few offsets. The species matures with long, white spines at the end of conical tubercles, distinct among the Mammillaria. Between these tubercles is white wool. Foliage tissue is a teal-blue to dark seafoam-green. [1]
Carmine-pink flowers are borne in a crown formation around the head of the plant, with blooming occurring in summer and autumn. Flowers are pollinated and develop into small, ovate fruits, which are technically edible and have a tart, fruity flavor. These fruits are consumed by birds, rodents and some reptiles, which aid in spreading the species' seed to new locations. [2]
Mammillaria geminispina is one of several Mammillaria species to be cultivated. [3] It has gained the Royal Horticultural Society's Award of Garden Merit. [4] [5]
Mammillaria is one of the largest genera in the cactus family (Cactaceae), with currently 200 known species and varieties recognized. Most of the mammillarias are native to Mexico, while some come from the Southwestern United States, the Caribbean, Colombia, Guatemala, Honduras and Venezuela.

Cochemiea dioica, also called the strawberry cactus, California fishhook cactus, strawberry pincushion or fishhook cactus, is a cactus species of the genus Cochemiea. Its common name in Spanish is biznaga llavina. Temperature along with precipitation are consequential factors in distributing plant species.
Rhipsalis pilocarpa, the hairy-fruited wickerware cactus, is a species of flowering plant in the cactus family that is endemic to Brazil. Scarce in the wild, it is known only in a small number of isolated locations. Its status is listed as "vulnerable" by the IUCN Red List.

It is among the most common and most variable of its genus in nature, and is a popular subject for cultivation. It has gained the Royal Horticultural Society's Award of Garden Merit.

Growing to 10 cm (3.9 in) tall by 50 cm (20 in) wide, this tiny plant forms colonies of spiny stems with relatively large, lemon yellow flowers in spring.
