  1. I love this post!! I made the amateur mistake of leaving flowers out of my spring plot, but have planted some in my summer and will plant more in the fall. I just figured, as you hinted at, that growing something “inedible” in my food garden was a waste of space and time. The things is, many of the flowers on your list are edible or can be dried for tea!! Tea – bee balm, chamomile; edible – mums, clover, some geraniums, nasturtiums, marigolds, sunflowers

    Great post!
