water hyacinth, scientific name Eichhornia crassipes, belongs to the family Euphorbiaceae, commonly known as bag lotus, water lotus and false narcissus. Aquatic erect or floating herbs. Water hyacinth is an edible plant. Tasting like Chinese cabbage, it is an authentic "green vegetable". Stir-fried water hyacinth and boiled water hyacinth all taste very good, except its roots are harmless. You can also process and refine a food additive, which can treat colds. Water hyacinth is rich in amino acids, including 8 kinds of amino acids which are necessary for human survival and cannot be made by itself. Water hyacinth often grows in pieces on the water surface. Among the emerald-like oval leaves, there are many beautiful blue-purple flowers embedded, and the petiole expands like a gourd, which floats the whole plant on the water surface. When the water hyacinth first appeared at the Expo, it was known as the "lilac corolla to beautify the world", and the flowery language and symbol of the flowery language represented the meaning: this feeling will never change. The pursuit of feelings and life will never die. It depends on what kind of feelings you want to express. I think this is all right!
