Cactus is a diverse group of succulent plants in the family Cactaceae, known for their thick, fleshy stems, spines, and unique shapes. They thrive in full sunlight and well-drained soil, making them ideal for gardens, rockeries, desertscapes, and container planting. Cacti are extremely drought-tolerant and low-maintenance, and many varieties produce vibrant, long-lasting flowers that attract pollinators, adding texture, structure, and striking visual interest to outdoor spaces.
