CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2016/0697, filed Mar. 10, 2016, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The new cultivar is a seedling selection which resulted from the controlled pollination ofAnthurium andraeanum‘K52’, the seed parent, andAnthurium andraeanum‘K24’, the pollen parent. Both parents are developed and owned by the inventor and were never commercially released. Said cross was performed by the inventor in De Lier, The Netherlands, in June of 2013. Seeds were harvested from ‘K52’, sown, and grown to maturity in order to evaluate for unique characteristics which may be of commercial value. In September of 2014, after evaluating the seedlings for approximately one and a half years, one progeny was observed to exhibit good plant vigor with a unique combination of large, vibrant pink flowers and attractive foliage. In November of 2014, after further evaluation to confirm the unique characteristics, the new cultivar was selected for commercialization and given the breeder denomination ‘ARAANTPIN1’.

Asexual Reproduction: Asexual reproduction of ‘ARAANTPIN1’, by way of meristematic tissue culture, was first performed in November of 2014 at a laboratory in De Lier, the Netherlands. Four successive generations so produced have shown that the unique features of the instant cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘ARAANTPIN1’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in the instant environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the newAnthuriumcultivar ‘ARAANTPIN1’. These traits, in combination, distinguish ‘ARAANTPIN1’ as a new and distinct cultivar.1.Anthurium‘ARAANTPIN1’ is a robust, moderately vigor herbaceous perennial with a broad, upright growth habit; and2.Anthurium‘ARAANTPIN1’ exhibits dark green, glossy foliage with a moderately narrow cordate shape; and3.Anthurium‘ARAANTPIN1’ exhibits a large inflorescence, presented at and slightly above the foliage; and4.Anthurium‘ARAANTPIN1’ exhibits a vibrant pink spathe with a nearly horizontal aspect and a white spadix with a yellow tip.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinct variety ofAnthuriumknown as ‘ARAANTPIN1’, based upon observations made from a sample set of plants grown in 9 cm nursery pots which were approximately one year old from a rooted cutting. Plants were grown in a greenhouse in De Lier, The Netherlands, utilizing conventional greenhouse production protocols forAnthurium,which consisted of regular irrigation by way of ebb and flood watering benches and fertilizer applications of a complete fertilizer with micro nutrients at an EC value ranging from 1.0 to 1.8. No chemical pest or disease measures were utilized in production. Young plants are assimilated to the greenhouse under shade cloth and later move to light levels ranging from 3000 to 4000 lux for the final 5 months of production. Observation data was recorded in February of 2017.
