These leaves are characteristic of genus Brassica and not Chenopodium. The leaves of Chenopodium giganteum characteristically have rounded petioles and powdery bloom on the surface of leaves. Here petioles are flattened and leaves though glacous without a powdery bloom. The plant seems to be Brassica oleracea var. viridis L. (syn: B. acephala DC.), commonly known as Kale, collards or tree kale.
