Cacti, belonging to the Cactaceae family, are native to the Americas, from Canada in the north to Patagonia in the south. Their striking feature is the presence of areolas, small, cushion-like mounds from where spines, flowers, and new growth emerge. Cacti are often round or cylindrical, though sizes and shapes can wildly vary. Their adaptation to survive in arid and semi-arid environments, reducing leaves to spines and developing thick, water-storing stems, forms the core of their identity.
