Related to the daisy (Asteraceae), Zinnia is a genus of annuals, perennials, and small shrubs. Soft leaves are light green. Leaves vary by species from linear to a broad spatula shape. Flowers of wild species usually are like daisies, while new varieties are primarily doubles with mostly hidden or missing disc florets. Common colors found are yellow, pink, orange, and red to mahogany, but there are many more colors.
