Abstract: The drought tolerance of four species of shrub ground cover plants was studied. The results showed that the descend order of drought tolerance was Distylium buxifolium, Pyracantha fortuneana, Loropetalum chinense var. rubrum, Gardenia jasminoides var. radicans. Distylium buxifolium could survive under drought stress and be used as important color plant in city landscaping.
