| Abstract: | The accurate application of ornamental plants helpsto improve the quality of urban parks. 14 ornamental Helianthusannuus cultivars were introduced to field experiment inZhanjiang?in summer, and their phenological characteristics and14 phenotypic traits were observed, recorded and analyzed. Theresults showed that the phenological characteristics of differentornamental Helianthus annuus cultivars differed from each other,and phenotypic variation was abundant. Cluster analysis showedthat 14 ornamental Helianthus annuus cultivars were dividedinto 4 groups, which were consistent with results of phenologycharacters and phenotypic traits survey. The cultivars selection,planting adjustment and planting arrangement of ornamentalHelianthus annuus were further discussed. It provides scientificbasis for the multiple planting menthods, classification andaccurate application of ornamental Helianthus annuus |
