Landscape Attributes

Blue Star Juniper 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. It lends an extremely fine and delicate texture to the landscape composition which can make it a great accent feature on this basis alone.

This dwarf tree will require occasional maintenance and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. It has no significant negative characteristics.

Blue Star Juniper is ideal for use as a garden accent or patio feature, and is recommended for the following landscape applications;

  • Accent
  • Vertical Accent
  • General Garden Use

Planting & Growing

Blue Star Juniper will grow to be about 6 feet tall at maturity, with a spread of 3 feet. It tends to be a little leggy, with a typical clearance of 2 feet from the ground, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 30 years.

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 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. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America.
