The evaluation of ornamental value of potted ornamental grass varieties suitable for Fujian Province was carried out to screen out the ornamental grasses with the high potted ornamental value,in order to provide technical supports for the quick screening of ornamental grass cultivars suitable for potted planting,to put them into flower markets,to enrich ornamental potted varieties on the market and further promote the development of ornamental potted grass in China. Five indicators of flower color,leaf color,plant height,leaf number and the ornamental period were measured,and then 7 characters of 16 ornamental grass pots were measured using the grey correlation analysis method,including the degree of plant compactness,inflorescence,leaf color,plant ornamental quality,overall collocation effect,ornamental period and the growth potential quality. The whitefly grasshopper stood out in the comprehensive evaluation with the association degree to the ideal species at 0. 6505,which was followed by stone calamus with the gold leaf,money calamus and gold jirushipu. Their associations to ideal grass species were relatively close,i. e.,0. 6383,0. 6303 and 0. 6294,respectively,which indicated that they have a good overall character.Lepidopteris glauca and P. sinica were the two species with lower degree of association,whose associations to ideal species were respectively 0. 4887 and 0. 4845.
