The article deals with a study that compared the wood quality characteristics of common cypress species to gauge their performance in use. Three cypresses lusitanica, macrocarpa and Chamaecyparis nootkatensis x Cupressus macrocarpa were felled to compare lumber performance for appearance and structural purposes. Lusitanica is not popular as macrocarpa in New Zealand, but is now being planted more widely, as it is less susceptible to cypress canker. Each species had some advantages and disadvantages in growth, form and sawn timber characteristics. A higher frequency of branching is associated with Leyland aside from its straighter stems than the others. Surface checking was the worst problem for macrocarpa and pruned branch stub holes in Leyland. The serious disadvantages of lusitanica are warp on drying and lower stiffness.
