Pogonatherum plant named ‘Deplabun’

Abstract

A new and distinct cultivar of Pogonatherum plant named ‘Deplabun’, characterized by its upright and mounted plant habit; freely branching, bushy and relatively vigorous growth habit; and green-colored leaf blades.

Description

Botanical classification/cultivar designation: Pogonatherum paniceum cultivar Deplabun.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Pogonatherum plant, botanically known as Pogonatherum paniceum, and hereinafter referred to by the name ‘Deplabun’.

The new Pogonatherum was discovered by the Inventor in a controlled environment in Bleiswijk, The Netherlands in 2001, as a naturally-occurring whole plant mutation of Pogonatherum paniceum cultivar Compact, not patented. The new Pogonatherum was observed as a single flowering plant within a population of plants of the cultivar Compact. The selection of this plant was based on its plant size.

Asexual reproduction of the new Pogonatherum by tissue culture in a controlled environment in Evergem, Belgium since 2002 has shown that the unique features of this new Pogonatherum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Deplabun’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature 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 ‘Deplabun’. These characteristics in combination distinguish ‘Deplabun’ as a new and distinct Pogonatherum cultivar:

• • 1. Upright and mounded plant habit.
  • 2. Freely branching, bushy and relatively vigorous growth habit.
  • 3. Green-colored leaf blades.

Plants of the new Pogonatherum are most similar to plants of the parent cultivar Compact; however plants of the new Pogonatherum differ from plants of the cultivar Compact in the following characteristics:

• • 1. Plants of the new Pogonatherum are not as compact as plants of the cultivar Compact.
  • 2. Plants of the new Pogonatherum have longer internodes then plants of the cultivar Compact.
  • 3. Plants of the new Pogonatherum have larger and lighter green-colored leaves than plants of the cultivar Compact.

Plants of the new Pogonatherum can be compared to plants of the Pogonatherum cultivar Monica, not patented. In side-by-side comparisons conducted in Evergem, Belgium, plants of the new Pogonatherum differed from plants of the cultivar Monica in the following characteristics:

• • 1. Plants of the new Pogonatherum were stronger and bushier than plants of the cultivar Monica.
  • 2. Plants of the new Pogonatherum had darker green-colored leaves than plants of the cultivar Monica.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Pogonatherum, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Pogonatherum. The photograph comprises a side perspective view of a typical plant of ‘Deplabun’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photograph and following observations and measurements described plants grown in Bleiswijk, The Netherlands, under commercial practice during the summer in a glass-covered greenhouse. During the production of the plants, day temperatures were about 20° C. and night temperatures were about 18° C. Plants were grown with one plant per 12-cm container. Plants were about 15 weeks old when the photograph and description were taken.
