USPP19677P2 - Calathea plant named ‘HGV07’ - Google Patents

Abstract

A new cultivar of Calathea plant named ‘HGV07’ that is characterized by broad lance shaped leaves that are variegated and have white main veins.

Description

Botanical classification: Calathea

Variety denomination: ‘HGV07’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calathea plant botanically known as Calathea and hereinafter referred to by the cultivar name ‘HGV07’.

The new cultivar was discovered by the inventor in a cultivated area of Roosendaal, The Netherlands in October of 2004. ‘HGV07’ was discovered as a naturally occurring branch mutation within a population of unnamed Calathea plants.

Asexual reproduction by division of the new cultivar ‘HGV07’ was first performed in February of 2005 in Roosendaal, The Netherlands. 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 Calathea cultivar ‘HGV07’.

• • 1. Calathea ‘HGV07’ exhibits variegated leaves that have white main veins.
  • 2. Calathea ‘HGV07’ exhibits broad lance shaped leaves.

The closest comparison cultivars are Calathea ‘Insignis’ and ‘Makoyana’. The new cultivar ‘HGV07’ is distinguishable from ‘Insignis’ by the following characteristics:

• • 1. ‘HGV07’ has leaves with white main veins.
  • 2. ‘HGV07’ has wider leaves.

The new cultivar ‘HGV07’ is distinguishable from ‘Makoyana’ by the following characteristics:

• • 1. ‘HGV07’ has leaves with white main veins.
  • 2. ‘HGV07’ has lance shaped leaves. The leaves of ‘Makoyaha’ are ovate shaped.

The new cultivar ‘HGV07’ is distinguishable from the parent plant by the following characteristics:

• • 1. ‘HGV07’ has leaves with white main veins. The main veins of the parent plant are not white.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Calathea ‘HGV07’. The plant in the photograph shows an overall view of a 30 week 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 Calathea cultivar named ‘HGV07’. Data was collected in Maasland, The Netherlands from 30 week old greenhouse grown plants in 13 cm containers. The time of year was Winter and the average temperature was 21 degrees Centigrade during the day and 20 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. ‘HGV07’ 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.
