Abstract: To understand the application of perennial flower in the North Area of Shanghai Botanical Garden, six themed gardens in the North Area were taken as the research objects to investigate and count the perennial flower varieties and their ornamental traits. The results showed that there were 274 species of perennial flowers in the North Area, belonging to 27 families and 69 genera. The flowering periods of perennial flowers in the North Area covered all four seasons (spring, summer, autumn, and winter), providing a material basis for creating a plant landscape with flowers throughout the year. The rich flower and leaf colors have changed the monotonous scene of insufficient color in traditional flower borders.
