Zinnia are annual flowering plant haveing bright, solitary, daisy-like flower heads on a single, erect stem. The most common zinnia is "dahlia-flowered" and grows up to three feet. Other types are "cactus-flowered." Zinnia leaves are opposite and usually stalkless (sessile), with a shape ranging from linear to ovate, and pale to middle green in color. The flowers have a range of appearances, from a single row of petals, to a dome shape, with the colors white, chartreuse, yellow, orange, red, purple, and lilac. Zinnias seem especially favored by butterflies, and many gardeners add zinnias specifically to attract them.
