Title: Anthurium plant named ‘ARAANTRED5’

Description:
Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is  Anthurium andraeanum  Linden ex Andre. 
     Variety denomination: The inventive variety of  Anthurium  disclosed herein has been given the variety denomination ‘ARAANTRED5’. 
     CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to the Community Plant Variety Rights application number 2016/2991, filed Nov. 30, 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 of  Anthurium andraeanum  ‘K25’ (not patented), the seed parent, and  Anthurium andraeanum  ‘K20’ (not patented), 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 November of 2013. Seeds were harvested from ‘K25’, sown, and grown to maturity in order to evaluate for unique characteristics which may be of commercial value. In February of 2015, after evaluating the seedlings for approximately one year, one progeny was observed to exhibit durable foliage and durable large, bright red spathes. In March of 2015, after further evaluation to confirm the unique characteristics, the new cultivar was selected for commercialization and given the breeder denomination ‘ARAANTRED5’. 
     Asexual Reproduction: Asexual reproduction of ‘ARAANTRED5’, by way of meristematic tissue culture, was first performed in March of 2015 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 ‘ARAANTRED5’ 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 new  Anthurium  cultivar ‘ARAANTRED5’. These traits, in combination, distinguish ‘ARAANTRED5’ as a new and distinct cultivar.
         1.  Anthurium  ‘ARAANTRED5’ exhibits a compact growth habit with an abundance of foliage and inflorescences held at or slightly above the floral plane; and   2.  Anthurium  ‘ARAANTRED5’ exhibits relatively small, durable leaves which are dark green and glossy; and   3.  Anthurium  ‘ARAANTRED5’ exhibits large, durable spathes with a broad cordate shape and a vibrant red general coloration.

     BOTANICAL DESCRIPTION OF THE PLANT 
     The following is a detailed botanical description of a new and distinct variety of  Anthurium  known as ‘ARAANTRED5’, based upon observations made from a sample set of plants grown in 17 cm nursery pots which were approximately 10 month old from a rooted cutting. Plants were grown in a greenhouse in De Lier, The Netherlands, utilizing conventional greenhouse production protocols for  Anthurium , 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 electrical conductivity 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 October of 2017. 
     Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘ARAANTRED5’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such measurements are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on  The Royal Horticultural Society Colour Chart , The Royal Horticultural Society, London, sixth edition (2015). 
     A botanical description of ‘ARAANTRED5’ and comparisons with the parents and the most similar variety of common knowledge are provided below.
