Anthurium plant named ‘RIJN200023’

Abstract

A new cultivar of Anthurium plant named ‘RIJN200023’ that is characterized by an upright and outwardly spreading habit, dark green leaves, freely spathing, red spathes positioned above the foliage on strong erect scapes, long spathe life, large spathe size and white and yellow colored spadices.

Description

Botanical classification: Anthurium andreanum.

Variety denomination: ‘RIJN200023’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant botanically known as Anthurium andreanum and hereinafter referred to by the cultivar name ‘RIJN200023’.

‘RIJN200023’ is a hybrid that originated from the hybridization of the female or seed parent a proprietary Anthurium identified as 9821 (not patented) and the male or pollen parent a proprietary Anthurium identified as 9613 (not patented). The cultivar ‘RIJN200023’ was selected by the inventor in May of 2000 as a single plant within the progeny of the stated cross in De Lier, The Netherlands.

Asexual reproduction by tissue culture of the new cultivar ‘RIJN200023’ was first performed in July of 2000 in Melsen-Merelbeke, Belgium. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Anthurium cultivar ‘RIJN200023’.

• • 1. Anthurium ‘RIJN200023’ exhibits an upright and outwardly spreading habit.
  • 2. Anthurium ‘RIJN200023’ exhibits dark green leaves.
  • 3. Anthurium ‘RIJN200023’ exhibits free flowering.
  • 4. Anthurium ‘RIJN200023’ exhibits red spathes positioned above the foliage on strong erect scapes.
  • 5. Anthurium ‘RIJN200023’ exhibits long spathe life.
  • 6. Anthurium ‘RIJN200023’ exhibits a large spathe size.
  • 7. Anthurium ‘RIJN200023’ exhibits white and yellow colored spadices.

The closest comparison cultivar is Anthurium ‘Red Queen’ (not patented). The new cultivar ‘RIJN200023’ is distinguishable from ‘Red Queen’ by the following characteristics:

• • 1. ‘RIJN200023’ has spathes that are brighter red than ‘Red Queen’.
  • 2. ‘RIJN200023’ has larger spathes than ‘Red Queen’.
  • 3. ‘RIJN200023’ has spathes that are more heart shaped than ‘Red Queen’.
  • 4. ‘RIJN200023’ has foliage that is more durable than ‘Red Queen’.

The new cultivar ‘RIJN200023’ is distinguishable from the male parent Anthurium 9613 in having larger leaves.

The new cultivar ‘RIJN200023’ is distinguishable from the female parent Anthurium 9821 in having wider leaves and darker spathes.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Anthurium ‘RIJN200023’. The plant in the photograph shows an overall view of a 12 month old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Anthurium cultivar named ‘RIJN200023’. Data was collected in De Lier, The Netherlands from 12 month old greenhouse grown plants in 21 cm containers. The time of year was Summer and the average temperature was 23 degrees Centigrade during the day and 21 degrees Centigrade at night. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2001 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘RIJN200023’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
