Description

Genus and species: Anthurium andreanum L.

Variety denomination: ‘Anthucoen’.

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 ‘Anthucoen’. The new variety originated from a hybridization made in December 2001 in Bleiswijk, The Netherlands. The female parent was the red Anthurium pot plant ‘Anthepedi’ (U.S. Plant Pat. No. 18,644), while the male parent was the white Anthurium plant ‘3644-01’ (unpatented).

A single plant was selected in October 2003 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a five-year period. The new variety has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety were applied for in the European Union on Nov. 30, 2007, in Japan on Mar. 9, 2010. ‘Anthucoen’ has not been made publicly available or sold anywhere in the world for 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) Purple-pink colored medium sized spathe;
    • 2) Purple spadix;
    • 3) Rich shoot formation; and
    • 4) Compact plant habit.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds 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 48-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in 2009.

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

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

FIG. 3 shows three spathes at different stages of development, from left to right: just unfurled, 8 weeks, and approximately 30 weeks.

FIG. 4 shows the upper leaf surfaces: left side, 10 weeks old and right side, just unfurled.

 DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘Anthucoen’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 48-week old plants which were planted from tissue culture in 17 centimeter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in November of 2009. 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).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘Anthucoen’ differs from the female parent and commercial variety ‘Anthepedi’ (U.S. Plant Pat. No. 18,644), in that ‘Anthucoen’ has purple colored spathes, whereas ‘Anthepedi’ has red colored spathes. Additionally, the spathes of ‘Anthepedi’ are blistered, whereas the spathes of ‘Anthucoen’ are unblistered.

‘Anthucoen’ differs from the male parent ‘3644-01’ (unpatented), by having a purple colored spathe, smaller leaves and more basal branching, whereas ‘3644-01’ has a white spathe.

‘Anthucoen’ is comparable to the commercially available variety ‘Pink Champion’ (U.S. Plant Pat. No. 12,115). ‘Anthucoen’ differs from ‘Pink Champion’ in that ‘Anthucoen’ has purple colored spathes, while ‘Pink Champion’ has pink spathes.
