Description

Botanical designation: Anthurium andreanum.

Cultivar denomination: ‘AN2541672’.

CROSS-REFERENCED TO CLOSELY-RELATED APPLICATION

A 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. 20, 2024, application number 2024/2689. Foreign priority is not claimed to this application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum, commonly referred to as Flamingo Flower and hereinafter referred to by the name ‘AN2541672’.

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 Anthurium plants with durable red-colored spathes with white-colored venation.

The new Anthurium plant originated from a cross-pollination made by the Inventor in April, 2015 in Bleiswijk, The Netherlands of a proprietary breeding selection of Anthurium andreanum identified as code number 11-026818-0002, not patented, as the female, or seed, parent with a proprietary breeding selection of Anthurium andreanum identified as code number 11-026438-0004, not patented, as the male, or pollen, parent. The new Anthurium was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Bleiswijk, The Netherlands in January, 2017.

Asexual reproduction of the new Anthurium plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since May, 2019 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 ‘AN2541672’. These characteristics in combination distinguish ‘AN2541672’ as a new and distinct Anthurium plant:

- 1. Upright to outwardly arching plant habit.
- 2. Freely clumping growth habit; bushy and dense plants.
- 3. Ovate-cordate dark green-colored leaves.
- 4. Freely flowering habit.
- 5. Open inflorescences that are positioned above the foliar plane on strong scapes.
- 6. Ovate-cordate spathes that are red in color with white-colored venation.
- 7. Yellow to yellowish white-colored spadices.

Plants of the new Anthurium differ primarily from plants of the female parent selection in the following characteristics:

- 1. Leaves of plants of the new Anthurium are broader than leaves of plants of the female parent selection.
- 2. Spathes of plants of the new Anthurium are red in color whereas spathes of plants of the female parent selection are reddish purple in color.

Plants of the new Anthurium differ primarily from plants of the male parent selection in the following characteristics:

- 1. Spadices of plants of the new Anthurium are shorter than spadices of plants of the male parent selection.
- 2. Developing spadices of plants of the new Anthurium are yellow in color whereas developing spadices of plants of the male parent selection are light greenish yellow in color.

Plants of the new Anthurium can also be compared to plants of Anthurium andreanum ‘AN2809193’, disclosed in U.S. Plant Pat. No. 36,427. In side-by-side comparisons, plants of the new Anthurium differ primarily from plants of ‘AN2809193’ in the following characteristics:

- 1. Spathes of plants of the new Anthurium are narrower than spathes of plants of ‘AN2809193’.
- 2. Spadices of plants of the new Anthurium are yellow to yellowish white in color whereas spadices of plants of ‘AN2809193’ are red to light purplish pink 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 ‘AN2541672’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical inflorescence of ‘AN2541672’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 17-cm containers during the winter in a glass-covered greenhouse in Bleiswijk, The Netherlands. 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 about 22.5° C. and light levels ranged from about 100 μmol to about 200 μmol. Plants were twelve months from planting young rooted plants 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.
