Cryptomeria japonica 'Gyokuryu' / Gyokuryu Japanese cedar

Cryptomeria japonica 'Gyokuryu' is a fast-growing, broadly conical selection of Japanese cedar with coarse green foliage growing in sprays. After 10 years of growth, a mature specimen will measure 12 feet (4 m) tall and 8 feet (2.5 m) wide, an annual growth rate of 12 to 15 inches (30 - 38 cm).

This cultivar is presumed to be of Japanese origin. Joel Spingarn of Baldwin, Long Island, New York is credited with its U.S. introduction in 1967.
