Vegatable Garden Gourmet goodies! Edible flowers add color both to your containers and your meals. 'Bon Bon Mix' Calendula in the back container blooms in front of 'Rainbow' Swiss chard. At right, 'Starfire' marigold hovers above the shiny, round leaves of 'Salad Delight' red cabbage. In front, 'Patio' tomato and 'Summerlong' basil round out the edibles in this group of containers.
