Zinnia
Large, brightly colored blossoms that are often densely layered make heirloom zinnias a sunny summer favorite. Among the easiest flowers to grow, they can be seeded directly into the garden in warmer zones or started indoors in cooler locales. Give them some compost and they’ll continue to produce through the warmest summers. The variety of heirlooms available guarantee a colorful array of shapes and sizes in any garden.
