Pronunciation
(PY-see-uh)(PUN-gens)
Plant Type
All Plants, Trees Coniferous
Hardiness Zone
3
Sunlight
full
Moisture
average, doesn't like to be grown in hot dry sites
Soil & Site
prefers rich moist but is very adaptable
Fruit
cones, 2-4" long
Leaves
needles, 3/4" to 1.25" long, very stiff, green
Dimensions
The tree has strong apical dominance causing the formation of a conical shape. It reaches 30-60' tall by 10-20' spread in the landscape. In native sites it will get larger. Allow at least 10-12' from the center of the tree to any structure and looks best if planted in groups.
Maintenance
The secret to keeping this tree healthy and looking good is to prevent the bottom branches from being damaged by lawn mowers, weed whips, etc. Create a grass-less ring, extending one foot out from the tips of the branches. As the branches grow, expand the ring. One of the ugliest plants in the world is spruce with their bottom branches removed, creating the ice cream cone effect.
Propagation
seeds
Misc Facts
Pungens means "piercing" referring to the stiff needles. "Genus name is reportedly derived from the Latin word pix meaning pitch in reference to the sticky resin typically found in spruce bark". (#144)
Author's Notes
People just don't realize the potential size of these plants. Many times they are purchased as small, inexpensive plants and than planted to close to the driveway, side walk or house. I have seen Spruce planted between the sidewalk and the house. These plants are destined for the "chain saw".
