Picea glauca ‘Whiskey Blue Hills’ is a cold-hardy white spruce cultivar with striking powdery blue needles that lend a soothing bluish tone to the landscape. It has a dense, upright, pyramidal habit giving it a formal, clean silhouette. The tree produces attractive slender cones (initially purple-tinged, maturing to brown) that contrast nicely with the blue foliage. Its visual appeal makes it a great specimen conifer and a color accent in mixed borders or conifer gardens.

Growing & Maintenance Tips for Picea glauca 'Whiskey Blue Hills'
Plant ‘Whiskey Blue Hills’ in full sun and in soil that is moist but well drained. Once established, it shows moderate drought tolerance, though supplemental watering during long dry periods will improve needle retention and overall vigor. Prune only for shape or to remove dead/damaged branches. Mulch to retain soil moisture, and avoid overly hot or humid sites which can stress the tree and reduce its blue coloration.
