I have a small concrete slab of a patio. Probably 14 feet by 20 feet. One side borders the house, one side borders a chain link fence with a gate to the back yard. Two sides border a wooden privacy fence. Against the wooden fence the patio is bordered by a foot wide dirt area for plants. I need ideas for plants--area is mostly sunny for the day, shades over around 4pm. Three of the four sides have gates or doors. I can't figure out a layout for enjoying this patio space. Any thoughts??? Thanks.
