Zinnias are a warm-season annual and a staple for local cut flower markets and gardens alike. Zinnias require fewer inputs than other cut flowers, but site selection and management, trellising, harvest techniques, and cultivar traits are important considerations for success. This fact sheet provides a guide for producing zinnias in the Intermountain West and presents results from USU trials.
