Picea orientalis Bergman's GemGrowing in our garden for over 12 years, this dwarf form of Caucasian Spruce develops into a globose plant with many leaders sending out offshoots in all directions, creating a dense nest habit. The dark green needles are very short and densely packed on the branches. This spruce grows about 6 inches a year, and will eventually get to be 6 ft. tall.
