Description:

A very low, spreading shrub, with appealing evergreen foliage and lovely texture; one of the smallest forms of the species; excellent for accenting in a rock garden or borders

Ornamental Features

Koshyi Dwarf Japanese Cedar is a dwarf conifer which is primarily valued in the garden for its broadly spreading habit of growth. It has attractive bluish-green evergreen foliage which emerges light green in spring. The needles are highly ornamental and remain bluish-green throughout the winter.

Landscape Attributes

Koshyi Dwarf Japanese Cedar is a multi-stemmed evergreen shrub with a ground-hugging habit of growth. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

This is a relatively low maintenance shrub, and should not require much pruning, except when necessary, such as to remove dieback. It has no significant negative characteristics.

Koshyi Dwarf Japanese Cedar is recommended for the following landscape applications;

  • Mass Planting
  • Rock/Alpine Gardens
  • General Garden Use
  • Container Planting

Planting & Growing

Koshyi Dwarf Japanese Cedar will grow to be only 6 inches tall at maturity, with a spread of 24 inches. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. It grows at a slow rate, and under ideal conditions can be expected to live for 40 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 particular about its soil conditions, with a strong preference for rich, acidic soils, and is able to handle environmental salt. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a relatively sheltered location. Consider covering it with a thick layer of mulch in winter to protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America.

Koshyi Dwarf Japanese Cedar makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our experts for more information on how to protect it over the winter months.

This plant is not reliably hardy in our region, and certain restrictions may apply; contact the store for more information.
