Glauca Colorado Spruce
Glauca Colorado Spruce (Picea pungens 'Glauca')
Glauca Colorado Spruce (Picea pungens 'Glauca') is a seed-grown blue spruce selected for its consistently blue foliage and traditional pyramidal form. Larger and more vigorous than many grafted cultivars, this variety offers rugged structure, strong color, and dependable cold-hardiness, making it a classic evergreen choice for landscapes that demand year-round presence.
Distinctive Features
'Glauca' features a stately conical habit with stiff, horizontal branches and sharp, silver-blue needles. While needle color can vary slightly from plant to plant due to its seed-grown origin, most specimens exhibit rich, powdery blue tones throughout. It grows at a moderate to fast rate and forms a broad, symmetrical shape that provides structure and visual weight in large-scale designs.
