When beginning to think about permanent edible landscape design and forest gardening, taking in the general concepts of Permaculture can help tremendously. 

An edible forest can feature a number of natural layers. Fruit and nut bearing trees can create a canopy, dwarf trees shrubs and vines can create a natural under layer and be followed by low growing plants and ground cover. Plants that enjoy similar conditions and/or have a symbiotic relationship with one another are often arranged near one another in guilds. Careful consideration to conditions such as soil and exposure to sun as well as guild mates is wise given the significant investment and permanence involved in planting new trees, bushes and perennial flowers.
