Chamaecyparis lawsoniana 'Ellwood's Pygmy' is a dwarf, upright, columnar selection of Lawson cypress. Superficially, it resembles a broken Roman column, colored blue. Branching is dense and tight; and foliage is a nice powder-blue in color. It is considered to be one of the smallest of the "Ellwoodii" types, and a very nice plant to accent with Chamaecyparis lawsoniana 'Treasure Island'.
After 10 years of growth, a mature specimen will measure 3 feet (1 m) tall, an annual growth rate of 2 to 4 inches (5 - 10 cm).
This cultivar originated in the mid-1960s and introduced to the nursery trade by Wansdyde Nursery, Devizes, United Kingdom.
