Start with herbs. "Herbs are expensive to buy at the store," Seliga says. "So adding them to your landscape makes good economic sense." Reserve a small section of your vegetable garden for herbs or integrate them into your landscape. Rosemary, sages, thymes, winter savory, basils, and oregano all blend in well with flowering perennials.
Plant fruiting shrubs. Blueberries, currants, and elderberries are attractive shrubs in their own right, putting out pretty flowers in spring and, especially in the case of blueberries, a colorful fall show. Plus, they produce loads of delicious fruit.
Bring on the berries. Raspberries and blackberries reliably produce loads of fruit for years with minimal care. All they need is a sunny spot with well-drained soil, some basic pruning in winter, and a coat of compost over their beds in spring.
Go undercover. Low-growing, spreading strawberries, especially alpine varieties, make an attractive groundcover in sunny spots.
Plant these edible flowers, too.
