The peacock grass is an annual herbal flower of the genus Asteraceae. Plants are shorter, plant height 20-40 cm, plant type compact, multi-branched clustered, purple stems. Leaves opposite, pinnately divided, lobes lanceolate, with distinct oil glands on leaf margins. The head of the flower head is born. The flower wheel is dark red and the interior is yellow. It is also called red and yellow grass. Because of repeated hybridization between species, in addition to red and yellow, also cultivated pure yellow, orange and other varieties, as well as single-lobe, double-valve and other varieties.
