STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee, Dümmen Group B.V. of De Lier, The Netherlands on Aug. 24, 2020, application number 2020/1988. Foreign priority is not claimed to this application.

The Inventor and Applicant/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 and/or Applicant/Assignee. Inventor and Applicant/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 Coreopsis plant, botanically known as Coreopsis grandiflora, and hereinafter referred to by the name ‘Docormoswimp’.

The new Coreopsis plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program is to create uniform Coreopsis plants with numerous double-type inflorescences.

The new Coreopsis plant originated from a cross-pollination made by the Inventor in Aalsmeer, The Netherlands in July, 2017 of a proprietary selection of Coreopsis grandiflora identified as code number CP13-000002-014, not patented, as the female, or seed, parent with a proprietary selection of Coreopsis grandiflora identified as code number CP13-000003-003, not patented, as the male, or seed, parent. The new Coreopsis plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Aalsmeer in July, 2017.

Asexual reproduction of the new Coreopsis plant by vegetative cuttings in a controlled environment in Aalsmeer, The Netherlands since July, 2017 has shown that the unique features of this new Coreopsis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Coreopsis have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment 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 ‘Docormoswimp’. These characteristics in combination distinguish ‘Docormoswimp’ as a new and distinct cultivar of Coreopsis plant:

- 1. Upright and mounded plant habit.
- 2. Moderately vigorous growth habit and moderate growth rate.
- 3. Freely branching habit.
- 4. Medium green-colored leaves.
- 5. Freely flowering habit with numerous inflorescences per plant.
- 6. Double-type pompon inflorescences with yellow orange-colored ray florets.
- 7. Good garden performance.

Plants of the new Coreopsis differ primarily from plants of the female parent selection in inflorescence form as inflorescences of plants of the new Coreopsis have more ray florets and are denser than inflorescences of plants of the female parent. In addition, disc florets of plants of the new Coreopsis are not conspicuous whereas disc florets of plants of the female parent are clearly visible.

Plants of the new Coreopsis differ primarily from plants of the male parent selection in inflorescence type as inflorescences of plants of the new Coreopsis are double pompon-types whereas inflorescences of plants of the male parent selection are semi-double types.

Plants of the new Coreopsis can be compared to Coreopsis grandiflora ‘Decoreo16’, disclosed in U.S. Plant Pat. No. 25,241. Plants of the new Coreopsis differ primarily from plants of ‘Decoreo16’ in peduncle length as plants of the new Coreopsis have longer peduncles than plants of ‘Decoreo16’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Coreopsis plant. The photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Coreopsis plant.

The photograph on the first sheet (FIG. 1) comprises a side perspective view of a typical flowering plant of ‘Docormoswimp’ grown in a container.

The photograph on the second sheet (FIG. 2) comprises close-up views of typical leaves (upper and lower surfaces), inflorescence bud and inflorescences (upper and lower surfaces) from a typical flowering plant of ‘Docormoswimp’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 17-cm containers in Aalsmeer, The Netherlands during the summer initially in a greenhouse and finished in an outdoor nursery and under conditions and cultural practices which approximate those generally used in commercial Coreopsis plant production. During the production of the plants, day temperatures averaged 22° C. and night temperatures averaged 17° C. Plants were 17 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Second Edition, except where general terms of ordinary dictionary significance are used. Measurements represent averages for typical flowering plants.
