With your sandy soil you will need to add plenty of organic matter to build it up enough to sustain most plants. Add organic matter, such as manure, compost and leaves. You should take a sample of your soil to your county extension office to check the pH.

Here are some perennials that will do well in partial shade:
African Iris (Dietes spp) height 2 ft.
Blue Daze (Evolvulus glomerta) height 1-2 ft.
Blue Sage (Eranthemum pulchellum) height 3-5 ft.
Cardinal's Guard (Pachystachys coccinea) height 3-7 ft.
Daylilly (Hemerocallis spp.) height 1-2 ft.
Firespike (Odontonema strictum) height 6 ft,
Gerbera Daisy (Gerbera Jameson) 12 to 18 inches
