Title: Anthurium plant named ‘AN2884386’

Description:
Genus and species:  Anthurium andraeanum  L. 
     Variety denomination: ‘AN2884386’. 
     BACKGROUND OF THE NEW PLANT 
     The present invention comprises a new and distinct variety of  Anthurium , botanically known as  Anthurium andraeanum  L., and hereinafter referred to by the variety name ‘AN2884386’. 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 plant with a height of 33.0 cm to 38.0 cm having weakly blistered and medium glossy, white with red tips, orbicular-cordate, and durable spathes. 
     The new variety originated from a cross-pollination made in February 2013 in Bleiswijk, the Netherlands. The female parent was a light pink  Anthurium  pot plant designated ‘12870-01’ (unpatented), and the male parent was a pink  Anthurium  pot plant designated ‘ANTHFOFUN’ (U.S. Plant Pat. No. 30,527). 
     A single plant was selected from the progeny of the stated cross in December 2014. Asexual reproduction of the new variety by tissue culture in 2018 in Bleiswijk, the Netherlands, has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations. 
     Community Plant Variety Rights for this variety have been applied for in the European Union on Nov. 19, 2021 (Application no. 2021/2979), by Applicant who obtained the subject matter disclosed directly from the inventor. ‘AN2884386’ has not been made publicly available or sold anywhere in the world prior to the effective filing date of this application with the exception of sales or disclosures made one year or less before the effective filing date of this claimed invention by Applicant who obtained ‘AN2884386’ directly from the inventor. 
     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) Weakly blistered, medium glossy, white with red tips, and orbicular-cordate spathes;   2) Purplish-red spadices with red tips;   3) Green, deltoid leaves;   4) Petioles and peduncles of mature leaves and spathes, anthocyanin coloration is strong;   5) Spathes shape in cross section of middle zone is straight; and   6) Plant is rich in making shoots.

     DESCRIPTION OF THE NEW VARIETY 
     The following detailed description sets forth the distinctive characteristics of ‘AN2884386’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, the Netherlands. The plant history was taken on 34-week-old plants which were planted from tissue culture in 12-centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in June 2022. 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 (RHS) (2015).
