Zinnia

Although the genus contains about 17 species of annual, perennial and low shrubs native to the southwestern U. S., Mexico, Central America and South America, it is the cultivars of several species that have for years been popular garden favorites featuring colorful daisy-like flowers over a long summer to fall bloom period. Zinnia elegans (common zinnia) is perhaps the most widely grown species. Plants typically grow 1-3 (less frequently to 4) tall on upright, hairy, branching stems. They feature continuous summer to fall bloom in cool summer climates, but may slow down some at the peak of a typical zones 5 and lower summer, particularly if attacked by fungal diseases. Many flower forms (single, semi-double, double, ruffled, dahlia, cactus or small pompoms) and flower colors (shades of red, yellow, orange, pink, rose, lavender, purple, green and white) are available. Sizes range from small-flowered dwarfs (to 6” tall) to large-flowered giants (to 4’ tall). Ovate to lance-shaped, opposite leaves (to 5” long) usually clasp the stems.
