Abstract

A new and distinct cultivar of Anthurium plant named ‘AN2198403’, characterized by its upright to outwardly arching plant habit; freely clumping growth habit; bushy and dense plants; cordate dark green-colored leaves; freely flowering habit; inflorescences that are positioned within to slightly above the foliar plane on strong and mostly upright scapes; broadly cordate and glossy bright red-colored spathes; orangish yellow to yellowish white-colored spadices with tapering apices; and durable spathes that impart good inflorescence longevity.

Description

Botanical designation: Anthurium andreanum.

Cultivar denomination: ‘AN2198403’.

CROSS-REFERENCED TO CLOSELY-RELATED APPLICATIONS

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 2024/2686. 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 ‘AN2198403’.

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 medium-sized and freely-clumping Anthurium plants with durable, glossy, and red-colored spathes.

The new Anthurium plant originated from a cross-pollination made by the Inventor in May 2016 in Bleiswijk, The Netherlands of Anthurium andreanum ‘ANTHGESSIM’, disclosed in U.S. Plant Pat. No. 34,251, as the female, or seed, parent with a proprietary selection of Anthurium andreanum identified as code number 12-028793-0002, 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 February 2018.

Asexual reproduction of the new Anthurium plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since December 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 ‘AN2198403’. These characteristics in combination distinguish ‘AN2198403’ as a new and distinct Anthurium plant:

• • 1. Upright to outwardly arching plant habit.
  • 2. Freely clumping growth habit; bushy and dense plants.
  • 3. Cordate dark green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Inflorescences that are positioned within to slightly above the foliar plane on strong and mostly upright scapes.
  • 6. Broadly cordate and glossy bright red-colored spathes.
  • 7. Orangish yellow to yellowish white-colored spadices with tapering apices.
  • 8. Durable spathes that impart good inflorescence longevity.

Plants of the new Anthurium differ primarily from plants of the female parent, ‘ANTHGESSIM’, in spathe size as plants of the new Anthurium have broader spathes than plants of ‘ANTHGESSIM’.

Plants of the new Anthurium differ primarily from plants of the male parent selection in spathe color as spathes of plants of the new Anthurium are bright red in color whereas spathes of plants of the male parent selection are pink in color. In addition, spathes of plants of the new Anthurium are more rugose than spathes of plants of the male parent selection.

Plants of the new Anthurium can also be compared to plants of Anthurium andreanum ‘ANTHGLYNT’, disclosed in U.S. Plant Pat. No. 30,967. In side-by-side comparisons, plants of the new Anthurium differ primarily from plants of ‘ANTHGLYNT’ in the following characteristics:

• • 1. Plants of the new Anthurium are larger than plants of ‘ANTHGLYNT’.
  • 2. Spathes of plants of the new Anthurium are broader than spathes of plants of ‘ANTHGLYNT’.
  • 3. Spathes of plants of the new Anthurium are not as rugose as spathes of plants of ‘ANTHGLYNT’.

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 ‘AN2198403’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical inflorescence of ‘AN2198403’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 12-cm containers during the late autumn 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 ten 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.
