If space is an issue, purchase a window box and plant at the sunniest window sill in your house.
As for the front of each book, I have the window box which is just a clear plastic box, but I created a color picture of each dog and made a nice label of their name with a cute bit of my art and that is it.
Place tall, spiky, or straight-growth plants in the center of a round pot or in the middle of a window box to add height and interest.
Window boxes: As long as the window box is at least six inches deep, you can grow strawberries in window boxes.
These are plants selected by expert horticulturists and packaged together to create a beautiful window box or container garden.
