Abstract

A new and distinct cultivar of Gerbera plant named ‘Garheart’, characterized by its compact, broadly upright and uniformly mounding plant habit; dense and bushy appearance; numerous inflorescences with dark pink-colored ray florets; upright and strong scapes; and good garden performance and relatively tolerant to cold temperatures.

Description

Botanical designation: Gerbera hybrida.

Cultivar denomination: ‘GARHEART’.

BACKGROUND OF THE INVENTION

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

The new Gerbera plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new compact garden Gerbera plants with numerous attractive inflorescences, resistant to cold temperatures and good garden performance.

The new Gerbera plant originated from a cross-pollination made during the spring of 2010 in De Kwakel, The Netherlands of a proprietary selection of Gerbera hybrida identified as code number 07T092, not patented, as the female, or seed, parent with a proprietary selection of Gerbera hybrida identified as code number 05T236, not patented, as the male, or pollen, parent. The new Gerbera plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands during the summer of 2011.

Asexual reproduction of the new Gerbera plant by cuttings in a controlled environment in De Kwakel, The Netherlands since the summer of 2011 has shown that the unique features of this new Gerbera plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Gerbera have not been observed under all possible combinations of environmental conditions and cultural practices. 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 ‘Garheart’. These characteristics in combination distinguish ‘Garheart’ as a new and distinct Gerbera plant:

- 1. Compact, broadly upright and uniformly mounding plant habit.
- 2. Dense and bushy appearance.
- 3. Numerous inflorescences with dark pink-colored ray florets.
- 4. Upright and strong scapes.
- 5. Good garden performance and relatively tolerant to cold temperatures.

Plants of the new Gerbera differ from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Gerbera have slightly smaller inflorescences than plants of the female parent selection.
- 2. Plants of the new Gerbera have shorter flower scapes than plants of the female parent selection.
- 3. Ray florets of plants of the new Gerbera are lighter pink in color than ray florets of plants of the female parent selection.

Plants of the new Gerbera differ from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Gerbera have slightly larger inflorescences than plants of the male parent selection.
- 2. Ray florets of plants of the new Gerbera are darker pink in color than ray florets of plants of the male parent selection.

Plants of the new Gerbera can be compared to plants of the Gerbera hybrida ‘Gardreams’, disclosed in U.S. Plant Pat. No. 26,636. Plants of the new Gerbera differ from plants of ‘Gardreams’ in the following characteristics:

- 1. Plants of the new Gerbera have slightly smaller inflorescences with slightly smaller discs (centers) than plants of ‘Gardreams’.
- 2. Plants of the new Gerbera and ‘Gardreams’ differ slightly in ray floret color as plants of ‘Gardreams’ have red purple-colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Gerbera 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 Gerbera plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Garheart’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn and winter in 15-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial garden Gerbera production. During the production of the plants, day temperatures ranged from 10° C. to 16° C. and night temperatures averaged 10° C. Plants were six months old when the photographs were taken and 17 weeks old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
