Zinnia elegans, popularly called Common zinnia (elegant zinnia), is an annual, herbaceous plant that is part of the Zinnia genus, Compositae (Asteraceae) family. It is one of the most famous species of the Zinnia genus and has been used to create numerous varieties. Each branch of the stem ends with a calathidium (inflorescence), which is made up of small tubular flowers and large ligulate flowers, variously colored (pink, purple, yellow, orange, white, red, green, etc.). The flower heads can be simple or twisted, depending on the disposition of the ligulate flowers.
