Chalky soils: plants for
Chalky soils are alkaline and free-draining, and the depth of soil over chalk varies considerably. The key to gardening in these often drought-prone and nutrient poor soils is to select from the wide range of colourful plants that thrive in dry summers, need sharp drainage and moderate to low fertility. Limestone soils have similar characteristics.

How chalk is made
The base of pastel chalks is calcium sulfate (CaSO 4 ), which is derived from gypsum (CaSO 4 -2H 2 O), an evaporite mineral formed by the deposition of ocean brine; it also occurs disseminated in limestone. Chalk and dehydrated gypsum thus have similar origins and properties. Pastels also contain clays and oils for binding, and strong pigments.
