Blue Japanese White Pine gets its cultivar name ‘Glauca’ from the word glaucous, which is an adjective describing a dull grayish-green or blue color; this is, of course, a reference to the bluish color of the foliage.
Pinus parviflora ‘Glauca’ was the accepted name for all blue-needled forms of Pinus parviflora. That name has been corrected, and the currently accepted nomenclature is Pinus parviflora Glauca Group, which includes all of the blue-needled cultivars. Pinus parviflora ‘Glauca’ now refers to the standard Blue Japanese White Pine.
Pinus, the genus for Pines, is the sole genus in the subfamily Pinoideae, which is part of the larger family Pinaceae, the Pine family. Many other well-known conifers are also members of the Pine family, such as cedars, firs, hemlocks, spruces, and larches.
