Picea pungens 'Globosa'
Common name: 
Globosa Colorado Blue Spruce
Dwarf Globe Colorado Blue Spruce
PI-see-a PUN-jenz
Picea pungens var. glauca ‘Globosa’
‘Glauca Globosa’
Native to (or naturalized in) Oregon: 
  • Conifer, evergreen dwarf tree or shrub, slow growing, 3-5 ft ( m) tall, 5-6 ft ( m) wide in 10 years, mound-shaped, compact, densely branched, blue-green needles.
  • Sun to part shade.  Regular watering in dry summer areas.
  • Hardy to USDA Zone 3        It may have been selected in the Netherlands in 1937, or there about, and named 'Glauca Globosa'.  This plant is similar to 'R.H. Montgomery' (also called 'Montgomery') which was named by the New York Botanic Garden in 1949; there may be some confusion between these two plants in the trade (see below).
  • The following is from the Coenosium Gardens website (2010):  "Whether or not a nursery is actually growing 'Glauca Globosa' or 'R.H. Montgomery' is a moot point since for all intents and purposes there is no difference to the consumer.  Propagation of terminals will tend to produce 'R.H. Montgomery' while laterals will tend to produce 'Glanca Globosa'.  Enhance the desired effect with careful pruning and the nursery has whichever form it wants ("Poppycock!" says the conifer taxonomist.)  The taxonomist is bound "to get bent out of shape" over such a statement, but the nurseryman has to take a more "practical" attitude. There evidently is a 'Glauca Globosa' in a collection somewhere, but the nurseryman wants a cultivariant under this name, not necessarily the actual plant.  Those of us "in the know" must consider any 'Glauca Globosa' as a cultivariant unless the plant can be certified as possessing some characteristic other than growth habit or foliage that distinguishes it from 'R.H. Montgomery', and that characteristic has to be traceable back to the oldest labeled 'Glauca Globosa' that can be located."
