Description

Botanical designation: Gaura lindheimeri.

Cultivar denomination: ‘DOGAURGRALIGHTPINK’.

BACKGROUND OF THE INVENTION

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

The new Gaura is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program is to create new compact and early-flowering Gaura plants with attractive leaf and flower coloration.

The new Gaura plant originated from a cross-pollination in June, 2014 in Aalsmeer, The Netherlands of a proprietary selection of Gaura lindheimeri identified as code number GR-0014, not patented, as the female, or seed, parent with a proprietary selection of Gaura lindheimeri identified as code number GR-0007, not patented, as the male, or pollen, parent. The new Gaura plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Aalsmeer, The Netherlands in June, 2015.

Asexual reproduction of the new Gaura plant by vegetative tip cuttings in a controlled environment in Aalsmeer, The Netherlands since July, 2015 has shown that the unique features of this new Gaura plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Gaura 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 ‘Dogaurgralightpink’. These characteristics in combination distinguish ‘Dogaurgralightpink’ as a new and distinct Gaura plant:

    • 1. Compact, upright to broadly spreading plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Light red-colored flowers.
    • 6. Good garden performance.

Plants of the new Gaura can be compared to plants of the female parent selection. Plants of the new Gaura differ from plants of the female parent selection in the following characteristics:

    • 1. Plants of the new Gaura are more freely branching than plants of the female parent selection.
    • 2. Flower buds of plants of the new Gaura are darker in color than flower buds of plants of the female parent selection.

Plants of the new Gaura can be compared to plants of the male parent selection. Plants of the new Gaura differ from plants of the male parent selection in the following characteristics:

    • 1. Plants of the new Gaura are more compact than plants of the male parent selection.
    • 2. Flowers of plants of the new Gaura are light red in color whereas flowers of plants of the male parent selection are white in color.

Plants of the new Gaura can also be compared to plants of Gaura lindheimeri ‘Florgaure’, disclosed in U.S. Plant Pat. No. 26,518. In side-by-side comparisons, plants of the new Gaura differ from plants of ‘Florgaure’ in the following characteristics:

    • 1. Plants of the new Gaura are more freely branching than plants of ‘Florgaure’.
    • 2. Flowers of plants of the new Gaura are light red in color whereas flowers of plants of ‘Florgaure’ are red purple in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Gaura 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 Gaura plant.

The photograph is a side perspective view of a typical plant of ‘Dogaurgralightpink’ grown in a container.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 13-cm containers in an outdoor nursery in Aalsmeer, The Netherlands and under cultural practices typical of commercial Gaura production. During the production of the plants, day temperatures averaged 20° C. and night temperatures averaged 16° C. Plants were pinched one time one week after planting and were three months old when the photograph was taken and four months 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.
