Chamacyparis lawsoniana 'White Spot' is a columnar tree-form of Lawson cypress with random marbling of white variegation. New spring growth flushes white, later fading to green by summer. After 10 years of growth, a mature specimen will measure 7.5 feet (2.5 m) tall and 4 feet (1.2 m) wide, an annual growth rate of 8 to 10 inches (20 - 30 cm).
This cultivar originated as a sport found in 1943 on a specimen of Ch. lawsoniana 'Monumentalis Nova' by D.T. Poulsen Nursery, Copenhagen Denmark. It is known to be confused in the trade with Ch. lawsoniana 'Alumii Magnifica.'
