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.
