plant named ‘Kuegrapiso’

Abstract

A new and distinct cultivar of Pelargonium plant named ‘Kuegrapiso’, characterized by its compact and mounding plant habit; freely branching habit; pinching is not required; freely flowering habit; light red purple-colored flowers; no requirement for cooling treatment for flower initiation and development; and good container and garden performance.

Description

Botanical designation: Pelargonium crispum.

Cultivar denomination: ‘KUEGRAPISO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Pelargonium plant, botanically known as Pelargonium crispum and hereinafter referred to by the name ‘Kuegrapiso’.

The new Pelargonium plant is a product of a planned breeding program conducted by the Inventors in Dresden, Germany. The objective of the breeding program is to develop new Pelargonium crispum plants with uniform growth habit and unique flower colors.

The new Pelargonium plant originated from a cross-pollination made by the Inventors in Dresden, Germany in 2008 of two unnamed proprietary selections of Pelargonium crispum, not patented. The new Pelargonium plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Dresden, Germany in June, 2009.

Asexual reproduction of the new Pelargonium plant by vegetative terminal cuttings in a controlled greenhouse environment in Dresden, Germany since August, 2009, has shown that the unique features of this new Pelargonium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Pelargonium have not been observed under all possible environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Kuegrapiso’. These characteristics in combination distinguish ‘Kuegrapiso’ as a new and distinct Pelargonium plant:

• • 1. Compact and mounding plant habit.
  • 2. Freely branching habit; pinching is not required.
  • 3. Freely flowering habit.
  • 4. Light red purple-colored flowers.
  • 5. No cooling treatment required for flower initiation and development.
  • 6. Good container and garden performance.

Plants of the new Pelargonium differ primarily from plants of the parent selections in flower color. In addition, plants of the new Pelargonium are more freely branching than plants of the parent selections.

Plants of the new Pelargonium can be compared to plants of the Pelargonium crispum ‘Angeleyes Light’, not patented. In side-by-side comparisons conducted in Dresden, Germany, plants of the new Pelargonium differed from plants of ‘Angeleyes Light’ in the following characteristics:

• • 1. Plants of the new Pelargonium were more compact and bushier than plants of ‘Angeleyes Light’.
  • 2. Plants of the new Pelargonium had smaller leaves than plants of ‘Angeleyes Light’.
  • 3. Plants of the new Pelargonium were more freely flowering than plants of ‘Angeleyes Light’.
  • 4. Plants of the new Pelargonium had smaller flowers than plants of ‘Angeleyes Light’.
  • 5. Plants of the new Pelargonium and ‘Angeleyes Light’ differed in flower color as plants of ‘Angeleyes Light’ had light purple-colored flowers with red purple-colored markings on the upper petals.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Pelargonium plant 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 Pelargonium plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Kuegrapiso’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in Dresden, Germany and under cultural practices which closely approximate commercial Pelargonium production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were 13 weeks old when the photograph and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
