‘Conica’ is a dense, cone-shaped, semi-dwarf to dwarf shrub form with soft bright green foliage. It matures over a number of years to 10-13′ tall. Growth rate is 2-4″ per year. Needles (to 1/2″ long) are aromatic when crushed. Cones are rarely produced. Sharp pointed tip will broaden with age. ‘Conica’ was discovered by J. G. Jack and Alfred Rehder at Lake Laggan, Alberta, Canada, in 1904. Plants are often trimmed into topiary forms when grown in containers.
Best grown in moist, well-drained soils in full sun. Tolerates some light shade. Best performance is in cold winter climates with cool summers. Site in areas with good air circulation to help rid the dense foliage of moisture. Somewhat intolerant of urban stresses such as air pollutants and salt spray. Short-lived plant in the Piedmont of NC.
