Taking the flower border of the residential area of Jinan City as the research object, the flowering time and plant height of 24 plants were recorded by field investigation and phenological observation, and the color of plants was compared with NCS A-61950 portable color card. The seasonal characteristics of the flower border in Jinan residential area were discussed from the perspectives of time vertical and horizontal combination, hierarchical structure and color dynamic characteristics. The results showed that: (1) the flowering period was mainly concentrated in spring, and the top three dominant species were Ageratum conyzoides, Antirrhinum majus and Salvia farinacea. (2) Plants cover 5 color schemes, 14 hues, 28 NCS standard colors, purple, white, yellow are the main components of flower color. (3) The average plant growth rate was the highest in spring, and the coordination between plant height and flower border landscape was the lowest in June. The relationship between different plant growth rates and flower border landscape was as follows: fast growth rate > slow growth rate. According to the results of the study, the 24 plants with long flowering period, long flowering duration and elegant plant growth can be selected, which can provide a reference for the selection of flower border plants in Jinan and East China.
