Zinnias are a stunningly gorgeous annual that bring an explosion of color to your garden. Ruffled daisy-like flowers grow atop long rigid stems, making them a popular choice for cut flowers. Butterflies and Hummingbirds find them irresistible ; your flowers will be covered with them. Plant in full sun in rich well drained soils in an area with good air circulation. This will help avoid powdery mildew. Luckly, Zinnias are also deer resistant.
