The name Glauca is common in the plant world, think Cedrus atlantica Glauca, Cupressus arizonica Glauca, Pinus parviflora Glauca, all blue-gray plants. The nice thing is that the blue color becomes even more intense under dry conditions. The color has been popular for Christmas in recent years. The blue variety of the popular Conica is the Picea glauca ‘Sanders Blue’. We have them available in sizes 30-40 C3, 40-50 C3 and 50-60 C5.
