Zinnias are one of the few plants that are true annuals. They are fast-growing, warm-season annual flowers that bloom with abandon and require only minimal care. Zinnia elegans has lance-shaped, rough leaves. It has a wide variety of bold-colored, rounded flowers. They are also nice for adding dramatic color to a container.

Zinnias are the easiest annuals to grow, as they are low-maintenance, grow quickly, and bloom heavily. The vibrant, tropical colors of zinnias work well in a hot border, picking up the hues of other reds and oranges. They are an excellent choice for first-time flower growers and for anyone who wants to add a splash of color to their garden.
