Title: Anthurium plant named ‘ANTHEUBP’

Description:
Genus and species:  Anthurium andreanum  L. 
     Variety denomination: ‘ANTHEUBP’. 
     BACKGROUND OF THE NEW PLANT 
     The present invention comprises a new and distinct variety of  Anthurium , botanically known as  Anthurium andreanum  L., and hereinafter referred to by the variety name ‘ANTHEUBP’. The new  Anthurium  plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, the Netherlands. The objective of this breeding program was to create a new 34.0 cm to 38.0 cm height plant with bright pink, shiny, orbicular-cordate and very durable spathes that are flowering continuously through the year. 
     The new variety originated from a cross-pollination made in November 2008 in Bleiswijk, The Netherlands. The female parent was a red  Anthurium  pot plant designated ‘10520-01’ (unpatented), and the male parent was also a red  Anthurium  pot plant designated ‘9863-01’ (unpatented). 
     A single plant was selected from the progeny of the stated cross in September 2010 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a 5.5-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations. 
     Plant Breeder&#39;s Rights for this variety have been applied for in the European Union on Nov. 6, 2014. ‘ANTHEUBP’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing of this application. 
     SUMMARY OF THE INVENTION 
     The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands:
         1) Shiny, bright pink, orbicular-cordate spathe;   2) White spadix with yellow tip; and   3) Green elliptical leaves.

     DESCRIPTION OF THE NEW VARIETY 
     The following detailed description sets forth the distinctive characteristics of ‘ANTHEUBP’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 44-week old plants which were planted from tissue culture in 14-centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in March 2016. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2015).
