I did not plant these zinnias. They just appeared in a shrub border. And it is just one beautiful plant. And what is even crazier is that I love zinnias and have planted them in the past with no success. They have been short and get some dusty looking diseases. But not this one. It was probably from a seed dropped by a bird but it is exactly the right kind of plant I want. So I am going to do what my mother in law does---save the seeds and replant next year.
