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.

'''''Zinnia''''' is a [[genus]] of 20 species of [[Annual plant|annual]] and [[perennial plant|perennial]] [[plant]]s of family [[Asteraceae]], originally from scrub and dry grassland in an area stretching from the [[American Southwest]] to [[South America]], but primarily [[Mexico]], and notable for their solitary long-stemmed flowers that come in a variety of bright colors.

Zinnia leaves are opposite and usually stalkless, 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 are popular [[garden]] flowers, usually grown from seed, and preferably in fertile, [[humus]]-rich, and well-drained soil, in an area with full sun.  They will reseed themselves each year. Over 100 [[cultivar]]s have been produced since selective breeding started in the [[19th century]].

''Zinnia elegans'' is the familiar species, originally from Mexico and thus a warm-hot climate plant. Its leaves are lance-shaped and sandpapery in texture, and height ranges from 15 cm to 1 meter.

Those commonly grown in the garden are usually frost-tender annuals which should be planted in sun, away from drafts. Keep soil moist, making sure it is well drained.  They can tolerate dry periods. Extending the flowering can be done by deadheading often. Often will reseed.  
   −
Zinnias seem especially favored by [[butterfly|butterflies]], and many gardeners add zinnias specifically to attract them.
