They have thin, flexible scales 15-20 mm long; the bracts just above the scales are the longest of any spruce, occasionally just exserted and visible on the closed cones.
The second is a closed cone: two sides, one curved, one flat.
The cones are 6-12 cm long and 3-4 cm broad, purple-blue before maturity; the scale bracts are short, and hidden in the closed cone.
The cones are 4-7 cm long and 1.5-2 cm broad, dark purple-blue before maturity; the scale bracts are long, green or yellow, and emerge between the scales in the closed cone.
In constructing the display, a closed, damp cone of suitable size is inserted into a narrow-mouthed bottle and then allowed to dry inside the bottle.
The cones are 6-12 cm long and 4-4.5 cm broad, green or purple ripening pale brown, with about 100-150 scales; the scale bracts are short, and hidden in the closed cone.
The cones are 6-12 cm long and 3.5-4.5 cm broad, with about 100-150 scales; the scale bracts are short, and hidden in the closed cone.
In others, the seeds are stored in closed ("serotinous") cones for many years until an environmental cue triggers the cones to open, releasing the seeds.
In constructing the pine cone in the bottle display, a closed, damp cone of suitable size is inserted into a narrow-mouthed bottle and allowed to open upon drying.
The cones are 9-17 cm long and 4-6 cm broad, dark purple before maturity; the scale bracts are short, and hidden in the closed cone.
