Description

Genus and species: Anthurium andreanum L.

Variety denomination: ‘Anthcaszim’.

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 ‘Anthcaszim’. The new variety originated from a spontaneous mutation from the variety ‘Anthbneq’ (U.S. Plant Pat. No. 15,286) in a large production clone of the variety ‘Anthbneq’ in a greenhouse in May 2005 in Bleiswijk, The Netherlands.

The female parent of the original variety ‘Anthbneq’ was a pink-colored Anthurium pot plant ‘634-01’ (unpatented). The male parent was an orange-colored flowering Anthurium pot plant ‘532-02’ (proprietary, unpatented). The original variety ‘Anthbneq’ was discovered and selected as a flowering plant from the progeny of the above cross in March, 1998 in a controlled environment in a glasshouse in Bleiswijk, The Netherlands.

The new variety ‘Anthcaszim’ was selected in May 2005 from a production clone of ‘Anthbneq’ and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a four-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. 26, 2009, in Japan on Mar. 9, 2010, and in Korea on Jun. 7, 2010. ‘Anthcaszim’ 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) A pink medium sized glossy spathe;
    • 2) White spadix;
    • 3) Compact plant habit; and
    • 4) Dark green glossy foliage.

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: 16 weeks, 8 weeks and just unfurled.

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

 DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘Anthcaszim’. 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).
