Cedar (Cedrus spp.) are large sized trees from the pine family. The coniferous, evergreen trees have a moderately fast growth rate and adapt to a range of climatic zones. Dwarf varieties of evergreen conifers like cedar do very well when planted in pots and large containers for use at entrances, patios and decks. Potted cedar also give good effect on balconies as a privacy screen. There are a number of small growing cedar varieties well adapted to growing in pots.
