Two of our favorite zinnias coming together in this firework display of color and pattern to create our Zinnia Swizzle Mix! Plenty of striking bicolor patterns shine on three layers of brilliant petals. Full, bushy plants grow just 12 to 14 inches high and wide, filled with blooms reaching three to four inches across. Once established, Zinnia Swizzle Mix is a heat loving variety that will tolerate full summer sun and arid conditions.
