The purpose of the present paper is to classify the high temperature stress tolerance of the differences among the cultivars of scarlet sage [Salvia splendens Sell ex Roem. & Schult], and the flooding and drought stress tolerance of the typical bedding plants under high temperature condition. Principal component analysis of the plant height ratio and the dry weight of aerial part ratio (high temperature treatment / ordinary temperature treatment) resulted in first principal component. The first principal component from principal analysis indicated the high temperature stress tolerance. According to the scores on first principal component, 5 cultivars ('Faora', 'Flamex 2000', 'Carabiniere Scarlet', 'Carabiniere Violet' and 'Sizzler Burgundy') of scarlet sage have the high temperature stress tolerance. In high temperature time of the rainy season period (from June 5th to July 27th), Calandrinia umbellate, Cathranthus roseus Tropicana Bright Eye', Gaillardia aristata 'Dwarf, Nierembergia hippomanica var. violacea 'Purple Robe', Rudbeckia hirta 'Sonora' and Tagetes patula 'March Yellow' have both the flooding stress tolerance and the drought stress tolerance. In high temperature time of all season (from June 5th to Septenber 12th), Gaillardia aristata 'Dwarf' and Nierembergia hippomanica var. violacea 'Purple Robe' have the high adaptation of the environment.
