'Argentea' ('Candicans') - click to enlarge
Dawes Arboretum. August 2003.
This extra glaucous, super silver variant occurs just like hyper-blue seedlings in the blue spruce
line. If you have room for just one cultivar this is still a nice choice.

CHARACTER var. concolor
(species typical)
Lowiana Group
(var. lowiana (Gord.) Lemm.)
Habit usually dense, crown often rectangular, forked trunks more common more open, often conical, less likely to have a forked trunk
Bark darker brown, not highly corky lighter brown, more corky
Needle position brush-like, evenly dispersed and uniformly erect on tops of shoots often v-shaped along branchets, having a separation down the upper part of the shoots.
Geographic origin of garden plants Numerous southwest to northwest US states, including CO, NM, and CA Oregon to Sierra Nevada Mts., a more limited range
NOTE: Today most conifer taxonomists do not accept the validity of these two taxa are botanical varieties. Differences are certainly apparent in cultivated plants in Europe and the US under these two names.  Wild plants are less clearly separated and do not meet the usual criteria for botanical varieties or subspecies. Other supposed differences in terms of branchlet color or cone color are considered unreliable. The above differences reflect cultivated plants and SOME wild plants. The RHS and others have adopted the Lowiana Group in place of var. lowiana. It is thus a strain or group of seedlings. One will stlll see plants in collections as botanical varieties and those plants in arboreta often can be separated by the traits above. This is another case of not knowing a wild population well enough and drawing early conclusions in literature from a rather incomplete and biased sample.
