Chamaecyparis pisifera 'Filifera Aurea' / Golden Thread-leaf Sawara cypress

Chamaecyparis pisifera 'Filifera Aurea' is a well-known and easily found cultivar that is overall quite similar to Ch. pisifera 'Filifera,' but growing somewhat slower with thread-like golden foliage. It grows in a similar mounding, broadly conical fashion and after 10 years, will measure 4.5 to 6 feet (1.5 - 2 m) tall, an annual growth rate of 6 to 8 inches (15 - 20 cm).

This cultivar almost certainly originated as a golden branch sport found, at some point on, 'Filifera.' The first mention of this plant was in the Journal of Royal Horticultural Society in 1889. It is also quite likely for such a mutation to have occurred more than once meaning that various similar clones are known in the nursery trade.
