Chamaecyparis lawsoniana 'Imbricata Pendula' is an fast-growing, broadly upright selection of Lawson cypress with extremely long filamentous, whipcord-like foliage.
[Derek Spicer in the RHS Encyclopedia of Conifers], describes it as an unusual, but beautiful tree.
After 10 years of growth, a mature specimen will measure 12 feet (4 m) tall and nearly 6 feet (2 m) wide, suggesting an annual growth exceeding 12 inches (30 cm).
This cultivar originated as a seedling selected in 1930 by R. E. Harrison Nursery, Palmerston, New Zealand. It was originally thought to be very hard to propagate and was therefore not mass-produced and released to the nursery trade until significantly later by D. Teese, Australia.
