Answer: You may be thinking of blue spruce (Pinaceae Picea pungens). This tree has evergreen needles, 3/4 to 1 1/4 inches long, stiff and very sharp (spine-like), displayed nearly straight out from twig, silvery blue to dark green. Strong acidic taste. Each needle is borne on a raised, woody peg.
Cones are 2 to 4 inches long, cylindrical, light brown in color, scales are flexible, pointed with jagged erose margins, mature in the fall.
Gray to red-brown bark, young trees with small, thin scales; older trees still scaly but with shallow furrows.
Blue spruce is a medium to large tree with pyramidal form reaching up to 80 feet tall. Branches appear layered, especially with age.
