Chamaecyparis lawsoniana 'Filiformis' is a small, open-branched, broadly conical selection of Lawson cypress with arching pendulous branches, gray-green whipcord-like foliage and long, hanging shoots. A plant will typically grow 6 to 12 inches (15 - 30 cm) annually, reaching a height of 4 to 6 feet (1.3 to 2 m) tall and two-thirds as wide after 10 years.
This is a very old cultivar in the nursery trade, having been introduced in Belgium around 1877.
