Eat Your Yard! (Gibbs Smith, 2010) has information on 35 edible plants that offer the best of both landscape and culinary uses.

Design a beautiful edible front yard with the basic principles of good garden design: structure, repetition, form, texture and color. C. J. Hall says: I'm not into formal garden structure myself, but this is an interesting idea for beginning to grow food without shouting "free food here."
