USPP28259P3 - Anthurium plant named ‘ANTHDOTFAN’ - Google Patents

Abstract

A new and distinct variety of Anthurium plant named ‘ANTHDOTFAN’ particularly distinguished by having red, cordate and very durable spathes that retain the original color for a very long period of time, brown and cordate, durable leaves, pinkish cataphylls, reddish brown peduncles, rich flowering continuously throughout the year and a plant height of 30 cm to 35 cm, is disclosed.

Description

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHDOTFAN’.

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 ‘ANTHDOTFAN’. The new variety originated from a hybridization made in September 2006 in Bleiswijk, The Netherlands. The female parent was a dark red Anthurium pot plant designated ‘9842-01’ (unpatented), and the male parent was a red Anthurium plant designated ‘9632-01’ (unpatented).

A single plant was selected in November 2008 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a seven-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. 18, 2013. ‘ANTHDOTFAN’ 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) Red, cordate spathe;
  • 2) White spadix with yellow tip;
  • 3) Brown cordate leaves;
  • 4) Reddish-brown peduncle; and
  • 5) Pinkish cataphyll.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms 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 40-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in August 2015.

FIG. 1 shows the overall plant habit, including blooms and foliage.

FIG. 2 shows a close-up of the mature spathe.

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

FIG. 4 shows a close-up of the upper mature leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHDOTFAN’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 40-week old plants which were planted from tissue culture in 14-centimeter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in August 2015. 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).
