Chamaecyparis pisifera 'Golden Mop' / Golden Mop Sawara cypress

Chamaecyparis pisifera 'Golden Mop' is dwarf globose to conical, dense form of Ch. pisifera 'Filifera Aurea' with brighter color, finer foliage and much slower growth. Many dismiss this cultivar as simply a cultivarient, but it appears to be reliably stable. Over time it will become a dense bush of golden threads. After 10 years of growth, a mature specimen will measure 1.5 to 2 feet (50 - 60 cm) tall and wide, an annual growth rate of 1.5 to 2 inches (4.5 - 6 cm).

This cultivar originated as a mutation found on 'Filifera Aurea.' Humphrey Welch made first first mention of its existence in 1966 in World Checklist of Conifers. 'Golden Mop' is often seen listed as 'Filifera Aurea Nana,' 'Filifera Golden Mop' and 'Mops.'
