Prickly Pear Cactus
Opuntia spp.
The Prickly Pear Cactus (Opuntia species) is a sun-loving cactus known for its flat, paddle-shaped stems, which grow in stacked clusters and can take on sculptural, branching forms. Many varieties are grown not just for their form, but also for their edible pads (nopales) and colorful fruit (called tunas), although indoor-grown plants rarely fruit.
Its surface may appear harmless, but it’s covered in both large spines and tiny hair-like glochids that can easily irritate skin. It thrives on neglect, tolerates dry air and full sun, and prefers to be left alone — truly a plant that rewards restraint.
This cactus is ideal for experienced succulent owners or those with bright, sunny indoor conditions.
