STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR and APPLICANT/ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee of the instant application, Anthura B. V. of Bleiswijk, The Netherlands on Nov. 22, 2022, application number 2022/2633. Foreign priority is not claimed to this application.

The Inventor and Applicant/Assignee assert that no sales, offers for sale or public distribution of the instant plant 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 exception under 35 U.S.C. 102(b)(1) for disclosures 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 Anthurium plant, botanically known as Anthurium andreanum and hereinafter referred to by the name ‘AN2180756’.

The new Anthurium plant is a product of a controlled breeding program conducted by the Inventor in Bleiswijk, The Netherlands. The objective of the breeding program is to create new vigorous Anthurium plants with durable, large and attractive spathes.

The new Anthurium plant is a naturally-occurring whole plant mutation of Anthurium andreanum ‘Anthucoen’, disclosed in U.S. Plant Pat. No. 22,630. The new Anthurium was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Anthucoen’ in a controlled greenhouse environment in Bleiswijk, The Netherlands in October 2016.

Asexual reproduction of the new Anthurium plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since January 2017 has shown that the unique features of this new Anthurium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Anthurium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment 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 ‘AN2180756’. These characteristics in combination distinguish ‘AN2180756’ as a new and distinct Anthurium plant:

- 1. Upright to outwardly arching and uniform plant habit.
- 2. Freely clumping growth habit; bushy and dense plants.
- 3. Ovate to narrowly ovate to close to narrowly deltoid dark green-colored leaves.
- 4. Freely flowering habit.
- 5. Inflorescences that are positioned within to slightly above the foliar plane on strong and erect scapes.
- 6. Broadly ovate and strongly concave purplish pink and yellowish green-colored spathes and light purplish pink and yellowish green-colored spadices.
- 7. Durable spathes that impart good inflorescence longevity.

Plants of the new Anthurium differ primarily from plants of the mutation parent, ‘Anthucoen’, in spathe color as spathes of plants of the new Anthurium are purplish pink and yellowish green in color whereas spathes of plants of ‘Anthucoen’ are red purple in color. In addition, leaf apices of plants of the new Anthurium are apiculate with a mucronate tip whereas leaf apices of plants of ‘Anthucoen’ are narrowly acute.

Plants of the new Anthurium can also be compared to plants of Anthurium andreanum ‘Anthdubaq’, disclosed in U.S. Plant Pat. No. 27,889. In side-by-side comparisons, plants of the new Anthurium differ primarily from plants of ‘Anthdubaq’ in the following characteristics:

- 1. Spathes of plants of the new Anthurium are purplish pink and yellowish green in color whereas spathes of plants of ‘Anthdubaq’ are red purple in color.
- 2. Spathes of plants of the new Anthurium are strongly concave whereas spathes of plants of plants of ‘Anthdubaq’ are weakly concave.
- 3. Spadices of plants of the new Anthurium are light purplish pink and yellowish green in color whereas spadices of plants of ‘Anthdubaq’ are purple in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Anthurium. 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 Anthurium.

The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical plant of ‘AN2180756’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical inflorescence of ‘AN2180756’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 9-cm containers in Bleiswijk, The Netherlands during the summer in a glass-covered greenhouse. Plants were grown under conditions and practices which approximate those generally used in commercial Anthurium production. During the production of the plants, day and night temperatures ranged from about 19° C. to 22.5° C. and light levels ranged from 100 μmol to 200 μmol. Plants were nine months old when the photographs and the detailed description were taken. 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.
