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 ‘AN2437252’.
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 freely-clumping Anthurium plants with attractive, durable and glossy spathes.
The new Anthurium plant originated from a cross-pollination made by the Inventor in July 2012 in Bleiswijk, The Netherlands of a proprietary selection of Anthurium andreanum identified as code number 10-024278-0001, not patented, as the female, or seed, parent with a proprietary selection of Anthurium andreanum identified as code number 09-023494-0005, 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 July 2014.
Asexual reproduction of the new Anthurium plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since August 2016 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 ‘AN2437252’. These characteristics in combination distinguish ‘AN2437252’ 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 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. Narrowly ovate light red-colored spathes and yellowish pink-colored spadices.
- 7. Durable spathes that impart good inflorescence longevity.
Plants of the new Anthurium differ primarily from plants of the female parent selection in the following characteristics:
- 1. Plants of the new Anthurium are more freely clumping than plants of the female parent selection.
- 2. Spadices of plants of the new Anthurium are more tapering than 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. Plants of the new Anthurium have smaller spathes than plants of the male parent selection.
- 2. Spathes of plants of the new Anthurium are lighter red in color than spathes of plants of the male parent selection.
Plants of the new Anthurium can also be compared to plants of Anthurium andreanum ‘AN2562165’, disclosed in U.S. Plant Pat. No. 34,077. In side-by-side comparisons, plants of the new Anthurium differ primarily from plants of ‘AN2562165’ in spadix color as plants of the new Anthurium have light red-colored spadices whereas plants of ‘AN2562165’ have spadices that are darker red in color. In addition, scapes of plants of the new Anthurium are yellowish green in color whereas scapes of plants of ‘AN2562165’ are yellowish green in color strongly tinged with anthocyanin.
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 ‘AN2437252’ grown in a container.
The photograph on the second sheet (FIG. 2) is a close-up view of a typical inflorescence of ‘AN2437252’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in 14-cm containers in Bleiswijk, The Netherlands during the autumn 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 eleven 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.
