Swizzle Cherry & Ivory Zinnia Seeds' blooms create a stunning visual impact in the garden, thanks to their abundance on tidy, low-lying plants. Enormous three-to-four-inch blossoms are adorned with layers of petals that blanket the compact 10- to 12-inch plants entirely. Each flower displays layers of petals of vibrant cherry red, frosted with a delicate brush of white at each tip, then finished with a fine outline of crimson, resembling fireworks atop each stem.
