Ornamental Features

It has attractive grayish green foliage. The scale-like leaves are highly ornamental and turn plum purple in fall. The flowers are not ornamentally significant.

Landscape Attributes

Koster's Redcedar is a dense multi-stemmed evergreen shrub with a ground-hugging habit of growth. 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 shrub will require occasional maintenance and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats.

  • Mass Planting
  • General Garden Use

Planting & Growing

Koster's Redcedar will grow to be about 4 feet tall at maturity, with a spread of 9 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for 70 years or more.

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.
