One of the downsides, if it can be called that, about gardening is the obsession that can result from growing a single flower. For example, when I grew Zinnia ‘Green Envy’ I thought it would be the only Zinnia I would ever need. I quickly discovered that it would not be the case and every year I try a couple of new Zinnias, just to see. ‘Green Envy’ is still my first Zinnia love, but sometimes a gardener has to see what options are available to him. The problem arises when you try growing several cultivars and while planting them in the garden you discover that you forget which one is which. When plants are at the seedling stage, it can be rather difficult to tell them apart. I encountered this problem last year when I planned to sow seeds for Zinnia elegans “Green Envy,’ ‘Polar Bear and ‘California Giant.’ I did not want to create many homemade plant labels and spend an hour writing out the names. One afternoon while playing with the nephew it hit me: make color-coded plant labels and use them to keep track of the cultivars I was growing.
