- Conifer, evergreen shrub, prostrate, broad growing, stout branches, needles gray-blue, slow growing (about 8 cm per year).
- Sun.
- Hardy to USDA Zone 3 Some consider 'Blue Dwarf' as the same plant introduced as 'Glauca' in 1943 by Hugo F. Hooftman, Boskoop, Holland. P. pumila 'Glauca' received the Royal Horticultural Society's Award of Garden Merit in 1993. If there is but one plant, 'Glauca' is the name used in Europe, whereas 'Blue Dwarf' is the name used in much of the US. Van Gelderen and van Hoey Smith (1996) consider 'Blue Dwarf' an "illegitimate name" for 'Glauca'. A conifer grower in Oregon considers the two plants to be separate.
