Cacti and succulents are drought-tolerant plants known for their ability to store water in thick, fleshy tissues. They thrive in arid environments and require minimal watering, making them popular for low-maintenance gardening. Cacti, primarily from the Americas, often have spines and distinctive shapes, while succulents come in diverse forms and include genera like Aloe, Echeveria, and Sedum. Both types are adapted to survive in harsh conditions with well-draining soil and plenty of sunlight. Their unique appearance and resilience make them ideal for indoor and outdoor cultivation, adding visual interest and greenery with minimal care requirements.
