Small Cactus
The Indoor Cactus, scientifically known as various genera like Mammillaria, Echinocactus, or Opuntia, is a unique and resilient succulent admired for its striking architectural shapes and minimal care requirements. These desert natives feature thick, fleshy stems or pads adorned with spines or glochids (hair-like spines) that vary in size, color, and arrangement depending on the species.
Native to arid regions of North and South America, as well as parts of Africa, indoor cacti are well-suited for dry and sunny environments typical of homes and offices. They are favored as decorative houseplants due to their ability to thrive in low humidity and tolerate periods of neglect.
Indoor cacti come in a wide range of sizes and forms, from small, globe-shaped Mammillaria to towering columnar Echinocactus. Some, like the Opuntia, feature flat, paddle-like stems called pads. These plants can live for decades with minimal care, making them ideal for beginners and enthusiasts alike.
