Abstract
A new and distinct cultivar of Thuja tree named ‘RLH-CS’, characterized by its relatively compact, upright and narrowly pyramidal plant form; moderately vigorous growth habit and moderate to low growth rate; freely branching habit; dense and bushy form from base to top of the tree; lateral branches that are fine-textured and flexible and resist cracking and splitting; dark green-colored leaves that are soft and fine-textured and tolerate high humidity and high temperatures conditions; and good garden performance.
Description
Botanical designation: Thuja plicata.
Cultivar denomination: ‘RLH-CS’.
The present invention relates to a new and distinct cultivar of Thuja tree, botanically known as Thuja plicata, commonly known as Western Arborvitae and hereinafter referred to by the name ‘RLH-CS’.
The new Thuja tree is a naturally-occurring branch mutation of Thuja plicata ‘Clemson Select’, not patented. The new Thuja tree was discovered and selected on a single plant in 2005 by the Inventors from within a population of trees of ‘Clemson Select’ grown in an outdoor nursery environment in Long Creek, Oconee County, S.C.
Asexual reproduction of the new Thuja tree by semi-hardwood and hardwood cuttings in a controlled environment in Seneca, Oconee County, S.C. since 2010, has shown that the unique features of this new Thuja tree are stable and reproduced true to type in successive generations.
Trees of the new Thuja have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘RLH-CS’. These characteristics in combination distinguish ‘RLH-CS’ as a new and distinct Thuja tree:
-
- 1. Relatively compact, upright and narrowly pyramidal plant form.
- 2. Moderately vigorous growth habit and moderate to low growth rate.
- 3. Freely branching habit; dense and bushy form from base to top of the tree.
- 4. Lateral branches that are fine-textured and flexible and resist cracking and splitting.
- 5. Dark green-colored leaves that are soft and fine-textured and tolerate high humidity and high temperatures conditions.
- 6. Good garden performance.
Trees of the new Thuja can be compared to trees of the mutation parent, ‘Clemson Select’. Trees of the new Thuja differ primarily from trees of ‘Clemson Select’ in the following characteristics:
-
- 1. Trees of the new Thuja are relatively compact and have a narrowly pyramidal plant form whereas trees of ‘Clemson Select’ are larger and have a broader pyramidal plant form.
- 2. Trees of the new Thuja grow slower than trees of ‘Clemson Select’.
- 3. Leaves of trees of the new Thuja are softer, finer-textured and more tolerant to low temperatures than leaves of trees of ‘Clemson Select’.
Trees of the new Thuja can be compared to trees of Thuja standishii x Thuja plicata, ‘Green Giant’, not patented. In side-by-side comparisons, trees of the new Thuja differ primarily from trees of ‘Green Giant’ in the following characteristics:
-
- 1. Trees of the new Thuja are relatively compact, dense and have a narrowly pyramidal plant form whereas trees of ‘Green Giant’ are larger, more open and have a broader pyramidal plant form.
- 2. Trees of the new Thuja are not as vigorous as and grow slower than trees of ‘Green Giant’.
- 3. Leaves of trees of the new Thuja are softer, finer-textured and more tolerant to low temperatures than leaves of trees of ‘Green Giant’.
The accompanying colored photograph illustrates the overall appearance of the new Thuja tree showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Thuja tree.
The photograph is a side perspective view of a typical tree of ‘RLH-CS’ grown in a container.
The aforementioned photograph and following observations, measurements and values describe trees grown during the winter in #7 nursery containers in an outdoor nursery in Park Hill, Okla. and under cultural practices typical of commercial Thuja tree production. During the production of the trees, day temperatures ranged from −10° C. to 45° C. and night temperatures ranged from −26° C. to 35° C. Trees used in the photograph and for the description were four years old. In the following detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
