The spot chosen should get as much sun as possible. If the soil is at all heavy it will be necessary to improve the drainage. This is done by digging out an area one foot deep and mixing in a layer of stones, broken bricks or gravel into the subsoil.
Sensory Gardens: "Use plants that play on the senses, such as fuzzy lamb's-ear, textural succulents, or fragrant lavender." (though not many eat it, lamb's ear leaves are edible, and most fleshy succulents are edible)
