The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

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 ‘Dogaurgrabl’.

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, 2016 in Aalsmeer, The Netherlands of a proprietary selection of Gaura lindheimeri identified as code number GR14-000046-006, not patented, as the female, or seed, parent with a proprietary selection of Gaura lindheimeri identified as code number GR14-000012-001, 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, 2017.

Asexual reproduction of the new Gaura plant by vegetative tip cuttings in a controlled environment in Aalsmeer, The Netherlands since July, 2017 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 ‘Dogaurgrabl’. These characteristics in combination distinguish ‘Dogaurgrabl’ as a new and distinct Gaura plant:

• • 1. Compact and upright plant habit.
  • 2. Moderately vigorous growth habit and moderate growth rate.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. White-colored flowers with light pink-colored apices.
  • 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 flower color as plants of the new Gaura have white-colored flowers with light pink-colored apices whereas plants of the female parent selection have pure white-colored flowers.

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 flower color as plants of the new Gaura have white-colored flowers with light pink-colored apices whereas plants of the male parent selection have pure white-colored flowers.

Plants of the new Gaura can be compared to plants of Gaura lindheimeri ‘Belezza White’, not patented. In side-by-side comparisons, plants of the new Gaura differ from plants of ‘Belezza White’ in the following characteristics:

• • 1. Plants of the new Gaura are more compact than and not as tall as plants of ‘Belezza White’.
  • 2. Plants of the new Gaura have white-colored flowers with light pink-colored apices whereas plants of ‘Belezza White’ have pure white-colored flowers.

Plants of the new Gaura can also be compared to plants of Gaura lindheimeri ‘Gaudi Red’, not patented. In side-by-side comparisons, plants of the new Gaura differ from plants of ‘Gaudi Red’ in the following characteristics:

• • 1. Plants of the new Gaura have green-colored leaves whereas plants of ‘Gaudi Red’ have reddish-colored leaves.
  • 2. Plants of the new Gaura have white-colored flowers with light pink-colored apices whereas plants of ‘Gaudi Red’ have dark reddish pink-colored flowers.

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 ‘Dogaurgrabl’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in 17-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 21° C. and night temperatures averaged 15° C. Plants were pinched one time one week after planting and were 24 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
