Aquatic vegetables refer to vegetables planted on the water surface under soilless conditions. In the eyes of many people, putting vegetable seedlings in water without soil will kill them. In fact, all plants have the potential to grow in water, and you don't have to have soil to grow. Soil only serves to fix plants. Vegetables especially suitable for growing on water are celery, sweet corn, water bamboo, lettuce, chrysanthemum and so on.
