Chamaecyparis lawsoniana 'Nana Argentea' is a dwarf, broadly ovoid, densely branched selection of Lawson cypress with a silver-cream spring flush of foliage that later darkens to gray-green in summer. Once established a specimen will grow 3 to 4 inches (7.5 - 10 cm) annually. After 10 years of growth, one can expect a mature plant to measure 3 feet (1 m) tall and wide.
This is an old cultivar of unknown origin. It is thought to have originated in Germany and first described by Ludwig Beissner in 1884.
