Opuntia is the home planet of the Spicaryophylls.
Opuntia is a desert planet with very rare oasis. The Spicaryophylls are some of the few species that adapted to the climate. They are plants biologically, so they don't need food, which is extremly rare in the regions.
Opuntia was once an uninhabited planet, until it was visited by the strongest storm in its history. It gave birth to cyanobacteria that later evolved into Spicaryophylls.
Opuntia is a common species of cactus.
