plant named ‘ANTHFABLO’

Abstract

A new Anthurium plant named ‘ANTHFABLO’ particularly distinguished by having shiny, orange, orbicular cordate and durable spathes that retain the original color for a very long period of time, dark green and ovate-cordate, durable leaves, white spadices with yellow tips, early and rich flowering continuously throughout the year, and a plant height of 35.0 cm to 40.0 cm is disclosed.

Description

Genus and species: Anthurium andraeanum L.

Variety denomination: ‘ANTHFABLO’.

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 ‘ANTHFABLO’. 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 35.0 cm to 40.0 cm height plant with shiny and blistered, orange, orbicular cordate and durable spathes.

The new variety originated from a cross-pollination made in December 2009 in Bleiswijk, The Netherlands. The female parent was an orange Anthurium pot plant designated ‘11548-02’ (unpatented), and the male parent was an orange Anthurium pot plant designated ‘10867-04’ (unpatented).

A single plant was selected from the progeny of the stated cross in January 2012 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a 4-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in the European Union on Nov. 25, 2016. ‘ANTHFABLO’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective filing date 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 and blistered, orange and orbicular cordate spathes;
  • 2) White spadices with yellow tips;
  • 3) Green, ovate-cordate leaves; and
  • 4) Orange color of old flowers remains for a long period of time.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, bud and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 44-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in February 2018. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 3 shows a close-up of the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHFABLO’. 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 February 2018. 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).
