Outstanding Qualities

Bright apple green in color, somewhat like the skin of a Granny Smith, this cultivar of the native Japanese cedar is slow growing and semi dwarf at 6 to 8 feet in 10 years. The habit is generally mounding when young, but can be variable and eventually is more upright as it matures, often developing a leader; however, it can be pruned to keep its rounded form and from reaching 20 to 30 feet in 25 years. A handsome conifer year-round, 'Spiralis' is especially attractive in winter.
