Nidiformis’ is a slow-growing dwarf cultivar that typically grows to only 1-2’ tall and 3-4’ wide over the first 10 years, eventually maturing to as much as 8’ tall and 10-12’ wide over 30 years. It features spreading, horizontal to slightly ascending branches which form a dense, broad-rounded, shrubby, flattened globe. Mature plants have a depression or “nest” in the center of the flattened top, hence the common name of bird’s-nest spruce. Thin dark gray needles (to 3/4” long).
