Some metals are necessary nutrients for plant health while some are toxic pollutants. In this study, the ability of  Croton lindheimeri  to uptake essential element Fe or toxic metal Sr was assessed separately. The amounts of iron plaque on the root systems and the levels of Fe in  C. lindheimeri  collected from an iron-rich field were assessed. The results indicated that Translocation Factor (TF) of Fe in  C. lindheimeri  was around 1, with similar amounts of Fe in roots and shoots.  C. lindheimeri  seedlings were cultured in Sr solutions for 3 weeks to determine its potential to accumulate Sr. It was found that the roots of  C. lindheimeri  cultured in 20 mg/L Sr solutions sequestered 0.05 ± 0.01 mg Sr/g biomass. TF of Sr in  C. lindheimeri  was &gt;1. Further research is worthwhile to evaluate the potential of  C. lindheimeri  to remediate Sr contaminated sites. Novelty statementNo study related to the sequester of metals (either essential or non-essential metals) in  Croton lindheimeri  (goat weed) was found before. It was the first research about metal accumulation in goat weed.Fe plaque formation and iron sequester in the biomass of  Croton lindheimeri  were never studied in previous research.Very limited information about phytoremediation of Sr contaminated media was reported in previous studies, this study filled the gap by exploring the uptake of Sr in  Croton lindheimeri .
