This is the most well known of the 20 or so species in the zinnia genus. The wild form is a coarse, upright, bushy annual, to 30 in (76 cm) high, with solitary daisylike flowerheads on long stems, and opposite, sandpapery, lance shaped leaves. The ray flowers are purple, the discs yellow and black, and the entire head is about 2 in (5 cm) across. Gardeners love zinnias and there are at least a hundred cultivars in a diversity of flower colors and types, some with flowerheads up to 6 in (15 cm) across. There are zinnias with white, cream, green, yellow, apricot, orange, red, bronze, crimson, purple, and lilac flowers; zinnias with striped, speckled and bicolored flowers; zinnias with double, semi-double and dahlia-like "pompon" flowers; zinnias that range from dwarfs that don't exceed 6 in (15 cm) in height to cut flower beauties that get 3 ft (0.9 m) tall. These plants are easy to grow in well drained, rich loamy soil, in the open with full sun.
