Crystal Blue Spruce is primarily valued in the landscape for its distinctively pyramidal habit of growth. It has attractive blue evergreen foliage which emerges silvery blue in spring. The needles are highly ornamental and remain blue throughout the winter. The rough gray bark adds an interesting dimension to the landscape.
Crystal Blue Spruce will grow to be about 25 feet tall at maturity, with a spread of 10 feet. It has a low canopy, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 80 years or more.
This tree should only be grown in full sunlight. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for xeriscaping or the moisture-conserving landscape. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selection of a native North American species.
