Seeds from Zinnia Zowie Yellow Flame. This was 2006 All America Selection winner Zowie is a Zinnia with several layers of bright petals surrounding a big central red and yellow cone. When the petals open, they are bold magenta pink with yellow tips, and the pink gradually turns to rich red, giving you all 3 colors at once in a garden planting. Flowers measure 3 to 5 inches wide, so you really get a huge display of color from even a small planting. These plants are a good size for cut flowers, 30 to 36 inches tall and about 24 to 27 inches wide.
