More edibles that blend in

Artichoke (Cynara cardunculus): Grow this "superstar of front-yard food," as Ivette describes it, even if you don't like eating its big flower buds. Its architectural structure, downy leaves, and softball-size purple flowers are all highly ornamental.

Sage (Salvia officinalis): The mounding shape and gray leaves of this perennial Mediterranean herb make it a great front-row ornamental. Pink tinges in 'Tricolor' play off the burgundy flax, and the large leaves of 'Berggarten' echo the blue-green edging of the agave behind.
