I took this picture in my garden in May of this past year. When you are planning out this year's garden, don't discount any open space in your flower beds! I grew lazy rows of leeks, red cabbage, giant red mustard, and swiss chard right in my flower beds! They were surrounded by Rudbeckia, Ivory Halo Dogwoods, Peonies, Campanulas, and Delphiniums, and they fit right in!
(as a sidenote...I think I need to have some more of the bright yellow Rudbeckias!)
