Ornamental Features

Sentinel Juniper is a dwarf conifer which is primarily valued in the landscape or garden for its rigidly columnar form. It has attractive bluish-green evergreen foliage which emerges lime green in spring. The needles are highly ornamental and remain bluish-green throughout the winter. It produces blue berries from late spring to late winter.

Landscape Attributes

Sentinel Juniper is a dense multi-stemmed evergreen shrub with a narrowly upright and columnar growth habit. 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 is a relatively low maintenance shrub, and is best pruned in late winter once the threat of extreme cold has passed. It has no significant negative characteristics.

Sentinel Juniper is recommended for the following landscape applications;

• Accent
• Vertical Accent
• General Garden Use

Planting & Growing

Sentinel Juniper will grow to be about 5 feet tall at maturity, with a spread of 12 inches. It has a low canopy, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 30 years.

This shrub 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 selection of a native North American species.
