Photo of zinniaFew things say "summer!" as loudly as zinnias, and our "Splash of Color' seed kit has two different kinds to brighten your home with summer's colors year-round. The double flowers are a big four inches across! As with all flowering plants, you will get more blooms over a longer period if you cut off dead flowers - or better yet, cut them off when they begin to fade. And Zinnias are good at encroaching on their neighbor's space; don't let them!  Keep a pair of pruning shears next to your AeroGarden to use in controlling the width and height of the zinnias, and of all your AeroGarden plants.
