In planter gardening, stone includes natural stone, terrazzo, concrete, and reconstructed stone. Apart from natural  stone which has to be cut by machine  or carved by hand, garden  planters  made

from other stone  based  materials  can be formed  in a mould which allows  for the  mass production  of many types sizes and shapes of garden planters at relatively low prices.

       Reconstructed stone  - which is simply  stone "powder" bound with an adhesive  - is used to make authentic-looking  copies  of traditional planter shapes, like urns and pots mounted  on pedestals. Some manufacturers in an attempt  to make their new planters look old and weathered also use coloured  additives and surface coatings  in the production process. Many contemporary planters, however,  are available in simple square  or cylinder  shapes and their appeal relies on the smooth matt surfaces  and pale grey and white tones  that reconstituted  stone, concrete and terrazzo finishes have to offer.
