Spiralis’ is a very slow growing dwarf cultivar (1-3″ per year). It is an upright conifer that typically grows with twisted trunk in an irregular, narrow conical form with branches spiraling upward and outward. It may reach 3′ tall over the first 10 years, eventually maturing to as much as 8-12′ tall over time. Cup shaped, twisted, dark green foliage retains good color throughout winter.
