Heavy metal pollution has become one of the most serious environmental problems today. Remediation of heavy metal polluted soils is one of the significant topics in environmental restoration. As a plant based technology the success of phytoremediation is inherently dependent upon proper plant selection. The present study is an attempt to test the potential of the native species to remove heavy metals from the soil. A pot experiment was conducted to study the metal accumulation capacity of Canna indica L. Canna indica was known as Indian shot belongs to the family Cannaceae. High biomass herb species was selected to restrict the passage of contaminants into the food chain by selecting non-edible, disease resistant and tolerant plants and have very pleasant flowers. Based on the BCF and TF the plant species was used in Pb, Zn and Cr phytoextraction process and Ni and Cd phytostabilization processes. Finally it was concluded that the species was good accumulator of Pb, Ni, Zn, Cd and Cr.
