Chamaecyparis lawsoniana 'Ellwood's White' is a dwarf, conical selection of Lawson cypress with comparatively open branching and loose, dark-green foliage with copious flecks of white variegation. After 10 years of growth, a mature specimen will measure 4 feet (1.3 m) tall and 2 feet (60 cm) wide, an annual growth rate of 4 to 6 inches (10 - 15 cm).
This cultivar originated as a color sport, found in the mid-1960s, on a specimen of C. lawsoniana 'Ellwoodii'. Den Auden and Boom first described it and published the name in Manual of Cultivated Conifers.
