I would suggest one plant. Scented geraniums. Better plant it in a pot, so you can move it inside in Winter. The Rose Scented Geranium is wonderful, when you touch the leaves, they smell wonderful, they are even edible, so hit will not harm your daughter if she puts it in her mouth. It has flowers, but nothing to shout about. It is the scent that is very special about it. They have a lot of different scents, even chocolate sceented, but my favorite is the rose scented one.
