Description

Botanical designation: Chamaecyparis lawsoniana.

Cultivar denomination: ‘SMNCLUTL’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT & ASSIGNEE

The Inventor/Applicant and Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant and/or the Assignee. Inventor/Applicant and Assignee claim a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Chamaecyparis plant, botanically known as Chamaecyparis lawsoniana, and hereinafter referred to by the name ‘SMNCLUTL’.

The new Chamaecyparis plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program was to create new Chamaecyparis plants with strong branches, attractive plant form and good leaf color retention.

The new Chamaecyparis plant originated from an open-pollination in 2008 in Grand Haven, Mich. of Chamaecyparis lawsoniana ‘Sullivan’, not patented, as the female, or seed, parent with an unknown proprietary selection of Chamaecyparis lawsoniana as the male, or pollen, parent. The new Chamaecyparis plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich. in 2016.

Asexual reproduction of the new Chamaecyparis plant by softwood cuttings in a controlled greenhouse environment in Grand Haven, Mich. since 2016 has shown that the unique features of this new Chamaecyparis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chamaecyparis have not been observed under all possible combinations of 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 the new Chamaecyparis plant. These characteristics in combination distinguish ‘SMNCLUTL’ as a new and distinct cultivar of Chamaecyparis plant:

• • 1. Upright, arching and uniform plant habit and pyramidal plant form.
  • 2. Freely branching habit, dense and bushy plant form.
  • 3. Leaves that retain their yellow green coloration.
  • 4. Good garden performance.

Plants of the new Chamaecyparis can be compared to plants of the female parent selection, ‘Sullivan’. In side-by-side comparison, plants of the new Chamaecyparis differ primarily from plants of ‘Sullivan’ in the following characteristics:

• • 1. Plants of the new Chamaecyparis are broader and more pyramidal in shape than and not as narrow and conical in shape as plants of ‘Sullivan’.
  • 2. Leaves of plants of the new Chamaecyparis are thread-like in shape whereas leaves of plants of ‘Sullivan’ are scale-like in shape.

Plants of the new Chamaecyparis can also be compared to plants of Chamaecyparis pisifera ‘Dow Whiting’, disclosed in U.S. Plant Pat. No. 20,883. Plants of the new Chamaecyparis differ from plants of ‘Dow Whiting’ in the following characteristics:

• • 1. Plants of the new Chamaecyparis are larger than plants of ‘Dow Whiting’.
  • 2. Leaves of plants of the new Chamaecyparis are more green in color than and not as yellow as leaves of plants of ‘Dow Whiting’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Chamaecyparis plant 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 Chamaecyparis plant. The photograph is a side perspective view of a typical plant of ‘SMNCLUTL’ grown in an outdoor nursery.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following observations and measurements were grown during the summer in an outdoor nursery and three-gallon containers in Grand Haven, Mich. and under conditions which approximate commercial Chamaecyparis production. Plants were three years old when the photograph and description were taken. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from 5° C. to 10° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
