This study attempted to facilitate various groundcover plants, related to phytoremediation material, and advance shade plants with a heavy metal tolerance to contaminated soil in an urban shade space. Saxifraga stolonifera, which has commonly been used a landscape shade plants, was evaluated to determine its heavy metal tolerance to different concentrations(Control, 100mg․kg-1, 250mg․kg-1and 500mg․kg-1 treatment) of Cd, Pb and Zn in soil. The growth of Saxifraga stolonifera showed no significant tendency after the initial transplantation, but showed distinct changes with the respective treatment heavy metal types and concentrations over time. Especially, severe chlorosis, with more yellowish green leaves, was observed, with inhibition at Cd concentrations greater than 100mg․kg-1. Conversely, no external symptoms or growth retardation were observed with Pb and Zn concentrations less than 500mg․kg-1. Therefore, Saxifraga stolonifera can be applied as a long term phytoremediation species in soil contaminated with low concentrations of heavy metal in urban shade spaces.

바위취의 토양산도별 생육특성을 보면 초장, 엽수, 엽장, 엽폭 그리고 초폭에 있어서 모두 pH 4.5에서 생육량이 많았으며 pH가 높을수록 생육량이 현저하게 떨어지는 경향으로 통계적인 유의성이 인정되었다. 따라서 바위취 분화생산시 경량 배양토의 토양산도를 pH4.5~5.0 정도로 맞추어 주는 것이 pH 6.0보다 초기 활착이 빠르고 생육이 양호하며 균일성이 높아지는 것으로 나타났다.
