Cryptomeria japonica ‘Koshyi’

Cryptomeria japonica

Cryptomeria japonica 'Koshyi' is a flattened-globose to spreading dwarf selection of Japanese cedar with tidy symmetrical branching and dense, medium green, incurved foliage. After 10 years of growth, a mature specimen will measure 2 feet (60 cm) tall and 3 feet (90 cm) wide, an annual growth rate of 2 to 3 inches, significantly more outward than up.

This cultivar originated as a seedling selected in the early 1970s at Nakamura nursery, Yokohama, Japan. The names 'Koshiji' and 'Koshiji-sugi' are considered synonymous.
