What kind of Plants That like the sand?

Where abouts are you? We used to garden on a south facing sand dune and had no trouble growing almost anything. Sand does need a large amounts of humus adding frequently to make it fertile and moisture retentive.

Tree Lupins ( Lupinus arboreus ) are sub shrubs that grow on sand dunes, also Eryngium (Sea Holly) . Broom (Cytisus of various kinds) Sedums, Sempervivums,,,, Thyme. Rosemary. Sage., but as Owdboggy says Humus is essential for most plants and you might need an automated watering system for your (Specials), unless like me me you enjoy watering as it keeps you in touch with whats going on in the Garden. Good luck.

Have you tried cacti and succulents - they should like low nutrient and well drained material.

Look in other peoples gardens for plant ideas, or join the local Horticultural/garden club for local help. Try reading Beth Chatto's book The Dry Garden. An excellent read with lots of tips for no-watering plants.
