Magellan Mix Zinnias (Zinnia elegans Magellan Mix) are for those who love bright, vibrant color in their gardens. Many gardeners and growers consider them the best dwarf zinnias ever produced. They grow to 12-14 inches tall and as wide and all season long bear a profusion of blossoms in seven colors--ivory, pink, orange, cherry, yellow, scarlet, and coral. Note: The coral-color Magellan zinnia was an All-America Selection in 2005.
