Landscape Attributes

Degroot's Spire Cedar is a dense multi-stemmed evergreen shrub with a narrowly upright and columnar growth habit. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

This is a relatively low maintenance shrub, and usually looks its best without pruning, although it will tolerate pruning. It has no significant negative characteristics.

Degroot's Spire Cedar is recommended for the following landscape applications;

  • Shade
  • Vertical Accent
  • Hedges/Screening

Planting & Growing

Degroot's Spire Cedar will grow to be about 12 feet tall at maturity, with a spread of 3 feet. It has a low canopy with a typical clearance of 1 foot 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 50 years or more.

This shrub does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selection of a native North American species.
