Chamaecyparis lawsoniana 'Gnome' is a globose, very slow-growing dwarf bun-form of Lawson cypress with rich, deep green, crowded, semi-juvenile foliage. The crowded, congested foliage give the plant the appearance of a moss-covered rock. After 10 years of growth, a mature plant will measure only about 12 inches (30 cm) tall and wide, an annual growth rate of around an inch (2.5 cm).
This cultivar originated as a seedling selected around 1950 by W. Hart, Warnham Court, United Kingdom and introduced to the nursery trade in 1968 by Don W. Hatch, Chantrey Nursery, Honiton, Devon, United Kingdom.
