A 'boundless planting pool' typically refers to an expansive, often circular or oval-shaped pond or water feature designed for gardening and aquatic plants. Such pools are commonly found in parks, gardens, or as a decorative element in residential landscapes. They can be constructed using various materials like concrete, tiles, or prefabricated kits. The real scene depicted would show the pool in its natural or landscaped setting, possibly with aquatic plants, fish, and decorative elements like stepping stones or bridges.
