USPP20487P2 - Calathea plant named ‘PP0005’ - Google Patents

Abstract

A new and distinct Calathea musaica cultivar named ‘PP0005’ is disclosed, characterized a compact, bushy plant habit, and strongly variegated foliage.

Description

Latin name of the genus and species: Calathea musaica.

Variety denomination: ‘PP0005’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The new variety originated as a selection out of a group of plants of unnamed, unpatented variety of Calathea musaica. The inventor made the selection in a greenhouse in Holland during September 2005. The inventor is Adrianus Cornelis Dekker, a citizen of Holland.

Asexual reproduction of the new cultivar ‘PP0005’ was first performed in Holland by tissue culture in January 2007. ‘PP0005’ has since produced several generations by micro-propagation and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘PP0005’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PP0005’ These characteristics in combination distinguish ‘PP0005’ as a new and distinct Calathea cultivar:

• • 1. Compact, bushy plant shape.
  • 2. Small leaves.
  • 3. Strong contrasting colors in the leaves.

PARENT COMPARISON

Plants of the new cultivar ‘PP0005’ are similar to the parent variety in most horticultural characteristics. However, ‘PP0005’ differs from the parent variety in having a more compact plant shape, stronger variegation of the foliage and shorter peduncles.

The parent variety is also the best commercial comparison.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘PP0005’ grown in a greenhouse. This plant is approximately 1 year old, shown in a 11 cm pot. 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.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘PP0005’ plants grown in a climate controlled greenhouse in Munster, the Netherlands. Temperatures ranged from 18° C. to 22° C. at night to 18° C. to 22° C. during the day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Measurements and numerical values represent averages of typical plant types.
