Common name:

Native to (or naturalized in) Oregon: 
  • Conifer, evergreen tree, shrub, dwarf, 10-12 ft (3-4 m), slow growing, become broadly conical with time.  Needles light green, densely set, only 6-12 mm long, and radiate around the stem.  Very common in cultivation.
  • Sun.  Shelter from hot or cold winds and strong reflected sunlight. Red spider mites are often a problem in dry heat.  Will occasionally revert to the species type, i.e., loss of dwarf habit, more open, and longer needles.
  • Hardy to USDA Zone 2    This natural dwarf was discovered in the wild in Alberta, Canada in 1904.  Several newer cultivars, e.g., 'Laurin' and 'Elegans Compacta', were derived from 'Conica'.
  • glauca: glaucous (covered with a waxy bloom that rubs off readily), the leaves
  • Corvallis: northeast corner of 11th St. and Washington Ave.
