Chamaecyparis lawsoniana 'Silver Queen' is a large growing, open conical tree form of Lawson cypress with green foliage, tipped with silver-white new growth in spring that later fades to yellow-green and gray. After 10 years of growth, a mature specimen will stand 7.5 feet (2.5 m) tall and 4.5 feet (1.5 m) wide, an annual growth rate of 6 to 9 inches (15 - 22 cm).
This is an old cultivar of unknown origin, first described by Ludwig Beissner in 1891. It is thought to have originated in the United Kingdom.
