The Weeping Blue Spruce (Picea pungens 'Pendula') is a dwarf or slow-growing evergreen conifer with trailing, cascading branches and silvery-blue needles. In contrast to upright spruce, this tree functions as a living, blue-toned sculpture that can be utilized as groundcover or anchored for height. Although certain cultivars differ, it typically reaches heights of 2 to 6 feet and widths of 4 to 10 feet.
