Cypress is a Mediterranean tree and so can be grown outside only in the warmest parts(zones 7-11, down to 10F/-20C). It can, however, be grown in large containers–it is often a topiary subject–or small pots as bonsai and brought into a cool room in winter. It makes a dense screen when planted 3 feet/1 m apart and is great for lining roads or drives. It grows slowly but becomes a big tree–some consider it too big for residential planting. It does not need to be pruned. Once it is established, in 2-3 years, it is tolerant of salt and drought, but it will get much larger if it has enough water and nutrients and will be better able to resist disease and bugs. It needs good drainage or the roots will rot. It can live to be over 1000 years old! This tree is also known as Mediterranean Cypress, Funeral Cypress, and Tree of Death.
