Thuja plicata 'Filifera Nana' is a dwarf, weeping thread-branched form of western red-cedar that resembles ornamental grass. Branches grow out in all directions creating a mop-like form. Once uncommon, it has recently been usurped in popularity by 'Whipcord'. However, 'Filifera Nana,' however grows considerably slower than 'Whipcord; a mature specimen will only measure 18 inches (50 cm) tall and 3 feet (1 m) wide after 10 years of growth, half the rate of 'Whipcord.'
This cultivar's origin is unknown, but believed to have come from the USA a fairly long time ago.
