Zinnias are a wonderful companion flower. I found them to be an excellent trap plant for Japanese Beetles in my bean planting. Every morning I could go out and shake all the beetles from the top of the zinnias into a jar of soap water. My beans were saved and the zinnias hardly noticed the beetles. They are also good for detering tomato hornworms and attracting beneficial insects. Overall a beautiful and excellent choice to plant all around the garden.
