Abstract:This paper researches on cold tolerance of several sedums in light rooftop greening taking Reineckia carnea as comparison.By screening, the results showed Sedum plants have different adaptability with increase in cold stress. Integrated in physiology,Varieties of cold tolerance as follows: Sedum spurium ‘Coccineum’> Sedum acre> Lonicera japonica>Sedum linera> Sedum album > Sedum sexangulare > Reineckia carnea (CK)> Sedum polytrichoides > Sedum kamtschaticum,and this is consistent with the observation of field experiments.
