Description

[0001] Botanical designation: Anthurium andreanum.

[0002] Cultivar denomination: ‘AN2950768’.CROSS-REFERENCED TO CLOSELY-RELATED APPLICATION

[0003] 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 / 2681. Foreign priority is not claimed to this application.BACKGROUND OF THE INVENTION

[0004] 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 ‘AN2950768’.

[0005] 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 suitable to be produced as cut flowers with durable and uniquely-colored spathes.

[0006] The new Anthurium plant originated from a cross-pollination made by the Inventor in December 2007 in Bleiswijk, The Netherlands of a proprietary breeding selection of Anthurium andreanum identified as code number 04-010595-0001, not patented, as the female, or seed, parent with a proprietary breeding selection of Anthurium andreanum identified as code number 04-010538-0004, 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 December 2010.

[0007] Asexual reproduction of the new Anthurium plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since March 2015 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

[0008] 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.

[0009] The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘AN2950768’. These characteristics in combination distinguish ‘AN2950768’ as a new and distinct Anthurium plant:

[0010] 1. Tall, upright to somewhat outwardly arching plant habit; suitable for cut flower production.

[0011] 2. Narrowly cordate dark green-colored leaves.

[0012] 3. Freely flowering habit.

[0013] 4. Open inflorescences that are positioned above the foliar plane on strong scapes.

[0014] 5. Large broadly cordate-shaped spathes that are white and light yellow green in color with reddish venation and margins.

[0015] 6. Yellowish white and yellow green-colored spadices.

[0016] Plants of the new Anthurium differ primarily from plants of the female parent selection in the following characteristics:

[0017] 1. Spathes of plants of the new Anthurium are white and light yellow green in color with reddish venation and margins whereas spathes of plants of the female parent selection are yellow green in color.

[0018] 2. Spadices of plants of the new Anthurium are yellowish white and yellow green in color whereas spadices of plants of the female parent selection are light pink in color.

[0019] Plants of the new Anthurium differ primarily from plants of the male parent selection in the following characteristics:

[0020] 1. Spathes of plants of the new Anthurium are broader than spathes of plants of the male parent selection.

[0021] 2. Spathes of plants of the new Anthurium are white and light yellow green in color with reddish venation and margins whereas spathes of plants of the male parent selection are white in color.

[0022] 3. Spadices of plants of the new Anthurium are yellowish white and yellow green in color whereas spadices of plants of the male parent selection are yellow in color.

[0023] Plants of the new Anthurium can also be compared to plants of Anthurium andreanum ‘ANTHIUFEN’, not patented. In side-by-side comparisons, plants of the new Anthurium differ primarily from plants of ANTHIUFEN' in the following characteristics:

[0024] 1. Spathes of plants of the new Anthurium are white and light yellow green in color with reddish venation and margins whereas spathes of plants of ‘ANTHIUFEN’ are white in color flushed with green towards the basal lobes and with light green-colored venation.

[0025] 2. Spathe apices of plants of the new Anthurium are abruptly acute with long mucronate apices whereas spathe apices of plants of ‘ANTHIUFEN’ are narrowly acute.

[0026] 3. Scapes of plants of the new Anthurium are more heavily tinged with anthocyanin than scapes of plants of ‘ANTHIUFEN’.BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0031] The aforementioned photographs and following observations and measurements describe plants grown in nursery beds 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 cut flower 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 six years 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.
