plant named ‘ANTHINFAM’

Abstract

A new and distinct variety of Anthurium plant named ‘ANTHINFAM’ particularly characterized by having green spathes very well suited for cutflower culture, a yellow/white spadix with green tip, little shoot formation, a tall plant habit and dark green healthy foliage, is disclosed.

Description

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHINFAM’.

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 ‘ANTHINFAM’. The new variety originated from a hybridization made in November 2000 in Bleiswijk, The Netherlands. The female parent is a light green Anthurium plant designated ‘1535-02’ (unpatented), while the male parent was a cream Anthurium plant designated ‘00-271’ (unpatented).

A single plant was selected in May 2003 and has been asexually reproduced repeatedly by meristem tissue culture in Bleiswijk, The Netherlands over a five-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 Europe on Jan. 14, 2013. ‘ANTHINFAM’ 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) Green spathes very well suited for cutflower culture;
  • 2) Yellow/white spadix with green tip;
  • 3) Little shoot formation;
  • 4) Tall plant habit; and
  • 5) Dark green healthy foliage.

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 300-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in 2014.

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

FIG. 2 shows a close-up of the mature spathe. The base of the spadix is mature (yellow/white) and the tip of the spadix is immature (green).

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

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHINFAM’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 300-week old plants which were planted from tissue culture in 7-centimeter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in February 2014. 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.) (2001).

    • Shape.—Columnar.
    • Angle from spadix tip to peduncle.—120 degrees.
    • Texture.—When the spathe is unfurling the spadix is smooth. When the spadix matures, very small stigmata protrude. The stigmata are evenly distributed round the spadix. The spadix matures from base to top, slowly giving the spadix a somewhat coarse appearance.
    • Color.—The spadix becomes mature with time, with the spadix becoming yellow/white from the base to the tip. The distal green part becomes smaller until it changes color completely to yellow/white. Immature: RHS 146C. Mature: RHS 158B. Ages to: RHS 151A.
