| Abstract: | Growth laws have been studied for Sedum hybridum L. , S. spectabile Boreau, S. hybridu ＇ Immergrunch- ell＇, S. sarmentosum Bunge, S. spurium ＇ Coccineum＇ and S. spectabile. The results show that six kinds of Sedum L. can overwinter safely in natural conditions with high overwintering rate and strong cold resistance. The height and coverage of six kinds of Sedum L. increase continuously from April to August, the height increase fast from the last ten - day of May to August, and the coverage increase fast from Mav to August |

| Keywords: | Sedum L overwintering rate plant height coverage |
