Not used anything like as much as it once was, the Lawson Cypress will top out at around 50 ft.. As a hedge, like the majority of conifers, cutting back should be restricted to within the depth of the foliage. Cutting beyond this will prevent further lateral growth. Unlike Leylandii, Lawson Cypress has a pleasant resinous aroma. Commonly available forms will give a choice of form and colour. There are many ‘dwarf’ varieties suitable for rockeries or tubs.
