A compact rounded evergreen with striking steel blue foliage; grafted onto a single stem to form a blue lollipop, tends to become wider with age; a great patio tree, particularly effective accent among lower growing perennials and ornamental grasses

Ornamental Features:

Globe Blue Spruce (tree form) has attractive blue foliage which emerges silvery blue in spring. The needles are ornamentally significant but remain blue through the winter. Neither the flowers nor the fruit are ornamentally significant.

Landscape Attributes:

Globe Blue Spruce (tree form) is a dense evergreen dwarf tree, selected and trained to grow in a small tree-like form with the primary plant grafted high atop a standard. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

This is a high maintenance dwarf tree that will require regular care and upkeep. 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.

Globe Blue Spruce (tree form) is ideal for use as a garden accent or patio feature, and is recommended for the following landscape applications;

  • Accent
  • General Garden Use

Plant Characteristics:

Globe Blue Spruce (tree form) will grow to be about 6 feet tall at maturity, with a spread of 5 feet. It tends to be leggy, with a typical clearance of 3 feet from the ground, and should be underplanted with lower-growing perennials. It grows at a slow rate, and under ideal conditions can be expected to live for 60 years or more.

This dwarf 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 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.
