BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium scherzerianum , commonly referred to as Flamingo Flower and hereinafter referred to by the name ‘AN2181990’. 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 compact Anthurium plants with durable red-colored spathes. The new Anthurium plant originated from a cross-pollination made by the Inventor in January 2015 in Bleiswijk, The Netherlands of a proprietary breeding selection of Anthurium scherzerianum identified as code number 11-026379-0005, not patented, as the female, or seed, parent with a proprietary breeding selection of Anthurium scherzerianum identified as code number 09-023205-0006, 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 December 2016. Asexual reproduction of the new Anthurium plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since November 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 ‘AN2181990’. These characteristics in combination distinguish ‘AN2181990’ as a new and distinct Anthurium plant: 1. Upright to outwardly arching plant habit. 2. Freely clumping growth habit; bushy and dense plants. 3. Dark green-colored leaves. 4. Freely flowering habit. 5. Open inflorescences that are positioned above the foliar plane on strong scapes. 6. Ovate to broadly elliptic reddish orange-colored spathes. 7. Reddish orange to red-colored spadices. Plants of the new Anthurium differ primarily from plants of the female parent selection in the following characteristics: 1. Spadices of plants of the new Anthurium are shorter than spadices of plants of the female parent selection. 2. Spadices of plants of the new Anthurium are straighter than and not as curved as spadices of plants of the female parent selection. Plants of the new Anthurium differ primarily from plants of the male parent selection in the following characteristics: 1. Leaves of plants of the new Anthurium are shorter than leaves of plants of the male parent selection. 2. Spadices of plants of the new Anthurium are straight whereas spadices of plants of the male parent selection are curled. Plants of the new Anthurium can also be compared to plants of Anthurium scherzerianum ‘Antarto’, not patented. In side-by-side comparisons, plants of the new Anthurium differ primarily from plants of ‘Antarto’ in the following characteristics: 1. Spathes of plants of the new Anthurium are narrower than spathes of plants of ‘Antarto’. 2. Spadices of plants of the new Anthurium are shorter than spadices of plants of ‘Antarto’. 3. Spadices of plants of the new Anthurium are straight whereas spadices of plants of ‘Antarto’ are curled. 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 ‘AN2181990’ grown in a container. The photograph on the second sheet ( FIG. 2 ) is a close-up view of a typical inflorescence of ‘AN2181990’. DETAILED BOTANICAL DESCRIPTION The aforementioned photographs and following observations and measurements describe plants grown in 9-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 nine 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.
