The Zinnia genus contains many species with flowers ranging in sizes and colors, including red, yellow, pink, orange, and purple. Zinnia is one of the easiest annuals to grow. Each brightly colored, daisy-like flower blooms on a single, erect stem. The flowers bloom from June to frost and attract many pollinators, including hummingbirds and butterflies. They also make excellent fresh-cut flowers. This annual will re-seed itself for next season. It is susceptible to powdery mildew; minimize overhead watering and wetting leaves to avoid this disease. Use Zinnia in mixed borders, beds, butterfly gardens, and for colorful accents around your yard. Smaller varieties can be used for edging and in containers.
