Cacti come in a wide variety of shapes, sizes, and colors. They typically have thick, fleshy stems that are adapted to store water, which allows them to survive in arid environments. Many cacti also have spines or thorns covering them for protection. They are native to the Americas and found in desert and arid regions such as the southwestern United States, Mexico, and various parts of South America. However, they can also be found in other environments, including forests, grasslands, coastal areas, and our Green Cactus Pattern cursor.
