Abstract: The current study examines the bioaccumulation potential of Taif rose shrubs by analyzing the shrubs’ wastes. f. At Al-Shafa Highland, four farms with plants of different ages were chosen to collect soil samples and vegetative waste (leaves and stems) for morphological and chemical analysis. The tallest stem and largest crown diameter (184.2 and 243.5 cm, respectively) were found in the oldest (20-year-old) shrubs, which also produced the highest biomass of pruning wastes of stems and leaves (3.9 and 1.3 t/ha, respectively). The 10-year-old shrubs gathered the highest concentration of Co and Pb (1.74 and 7.34 mg kg −1 ) in the stem and the highest Fe, Mn, and Ni (18.55, 18.60, and 9.05 mg kg −1 ) in the leaves, while the youngest plants (4 years) accumulated the highest Cr and Zn (0.83 and 13.44 mg kg −1 ) in their leaves. The highest contents of Cd, Cr, Cu, Fe, Mn, Pb, and Zn were found in the oldest Taif rose stem (34.94, 1.16, 36.29, 49.32, 51.22, 24.76, and 32.51 g ha −1 ), while the highest contents of Co and Ni were found in the stems of plants that were 10 and 12 years old (3.21 and 9.54 g ha −1 , respectively). The Taif rose’s stem and leaves can absorb the majority of heavy metals that have been studied with BAF values greater than one. Significant relationships between various heavy metals in the soil and the same in the stems (Al, Co, and Pb) and leaves (Co, Fe, Mn, Ni, and Pb) of Taif roses have been observed. According to the current findings, the Taif rose is a promising viable and safe crop for heavy metals phytoremediation if it is grown in polluted soil because there is little to no risk of contamination in the use of its end products, high biomass of pruning wastes, and high efficiency of heavy metal removal.
