Abstract: The paper aims to select appropriate gardening aquatic flowers for future water landscape in Jinan, and provide scientific and rational basis and guidance. Using the questionnaire survey and expert evaluation method, we screened 45 kinds of aquatic flowers with high ornamental value. After 2 rounds of expert evaluation, the results were as follows: 12 aquatic flower species were ranked into the first grade Ⅰ (I ris pseudacorus, Iris ensata, Acorus calamus, Polygonum orientale, Typha orientalis, Phragmites australis, Arundo donax, Arundo donax var. versiocolor, Canna generalis, Thalia dealbata, Nelumbo nucifera, Nymphaea tetragona), which were of high application value in water landscape in Jinan; 16 species of aquatic flowers were classified into grade Ⅱ and 6 species into grade Ⅲ, the application value of aquatic flowers in grade Ⅱ and Ⅲ gradually decreased; 11 species of aquatic flowers were classified into grade Ⅳ(Juncellus serotinus, Mariscus umbellatus, Scirpus triangulatus, Rumex patientia, Ranunculus sceleratus, Oenanthe javanica, Sium suave, Marsilea quadrifolia, Myriophyllum verticillatum, Nasturtium officinale, Potamogeton distinctus), which were not suitable for the application in Jinan water landscape.
