A choice evergreen for the landscaper, featuring shiny silvery-blue needles that fade to a rich steel blue over the summer and retain their colors well through winter; a particularly hardy and large-growing color accent tree for the toughest locations

Landscape Attributes

Royal Blue Spruce is an evergreen tree with a strong central leader and a distinctive and refined pyramidal form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.

This is a relatively low maintenance tree. When pruning is necessary, it is recommended to only trim back the new growth of the current season, other than to remove any dieback. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

Royal Blue Spruce is recommended for the following landscape applications;

  • Accent
  • Vertical Accent
  • Windbreaks and Shelterbelts

Planting & Growing

Royal Blue Spruce will grow to be about 50 feet tall at maturity, with a spread of 20 feet. It has a low canopy, and should not be planted underneath 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.
