Zinnia elegans 'Queen Lime' features double pompom shaped flowers that shade from chartreuse to grass-green on tall (40 – 50") plants ideal for the sunny border and hot, dry summer weather. Zinnias are a favorite of American gardens, where they thrive in the hot summer weather. A native of deserts of Mexico, this popular annual produces flowers up to frost. Grow this zinnia in any well-drained soil and in full sun with good air movement (to decrease the incidence of foliar diseases). There are about 20 species of zinnias found in natural environments from the southern United States to South America.
