Very low volume, since it holds needles for years and never carpets the ground the way a pine does. The distinctive litter is the cones: 4-5 inch cones stand upright on the upper branches and disintegrate on the tree scale by scale instead of dropping whole, giving a slow rain of purple-brown scales and bare central spikes rather than anything rakeable.
30-50 ft tall by only 15-20 ft wide with slow growth (Morton) — much narrower than a blue spruce, which is why it fits lots a spruce would outgrow. Morton reports no serious pest or disease problems, so a well-drained site produces a long-term tree; removal is a mid-bracket conifer job, and the narrow spread often means it can be felled in one piece where there is room.
