Anthurium plant named ‘Anthcimwi’

Abstract

A new Anthurium plant particularly distinguished by having unique brown-red, durable spathes, dark-green, compact, durable leaves, a medium-long erect penduncle, rich shoot formation, flowers early and continuously throughout the year, a compact and full plant habit and a plant height of 30 cm to 35 cm, is disclosed.

Description

Genus and species: Anthurium andreanum L.

Variety denomination: ‘Anthcimwi’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the cultivar name ‘Anthcimwi’. The new cultivar originated from a hybridization made in 2000 in Bleiswijk, The Netherlands. The female parent was a red Anthurium pot plant ‘00-2935-05’ (unpatented), while the male parent was a brown Anthurium plant ‘00-3808-01’ (unpatented).

The new cultivar was selected in 2002 from a selection of the hybridization and has been asexually reproduced repeatedly by 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 cultivar was granted with the European Union on May 19, 2008. ‘Anthcimwi’ has not been made publicly available nor 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 cultivar when grown under normal horticultural practices in Bleiswijk, The Netherlands.

• • 1) Brown-red, durable spathes;
  • 2) Dark-green leaves that are compact and durable;
  • 3) Medium, long erect penducle which holds the inflorescence just above the foliage;
  • 4) A high leaf to inflorescence ratio;
  • 5) Rich shoot formation;
  • 6) Compact and full plant habit;
  • 7) Flowers early and rich and continuously throughout the year; and
  • 8) Is a potplant, with a plant height of 30 cm to 35 cm.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Anthcimwi’. 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-cm pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in November of 2007. 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).
