Cryptomeria japonica 'Spiralis' is a moderately fast growing broadly conical form of Japanese cedar with dense branching and needles that wrap around the branchlets in a "whipcord" fashion. After 10 years of growth, a mature specimen will measure 6 to 8 feet (circa 2m) tall and 2-thirds as wide, an annual growth rate of 6 to 8 inches (15 - 20 cm)
This cultivar originated in Japan in the mid 1800, or earlier; and is very popular world-wide in larger gardens and landscapes. The cultivar name was first published in 1844 by Siebold and Zuccarini in Flora Japonica.
