Abstract

A new and distinct cultivar of Gaura plant named ‘Summer Star Baby’, characterized by its compact, upright to broadly spreading plant habit; moderately vigorous growth habit; freely branching habit; freely flowering habit; light red purple-colored flowers; and good garden performance.

Description

Botanical designation: Gaura lindheimeri.

Cultivar denomination: ‘SUMMER STAR BABY’.

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 ‘Summer Star Baby’.

The new Gaura is a product of a planned breeding program conducted by the Inventor in Foxley, United Kingdom. The objective of the breeding program is to create new semi-upright Gaura plants with attractive leaf and flower coloration.

The new Gaura plant originated from an open-pollination in July, 2006 in Foxley, United Kingdom of a proprietary selection of Gaura lindheimeri identified as code designation OSEXM, not patented, as the female, or seed, parent with an unknown selection of Gaura lindheimeri 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 open-pollination in a controlled environment in Foxley, United Kingdom in July, 2008.

Asexual reproduction of the new Gaura plant by vegetative tip cuttings in a controlled environment in Foxley, United Kingdom since September, 2008 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 ‘Summer Star Baby’. These characteristics in combination distinguish ‘Summer Star Baby’ as a new and distinct Gaura plant:

    • 1. Compact, upright to broadly spreading plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Light red purple-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 compact than plants of the female parent selection.
    • 2. Flowers of plants of the new Gaura are darker red purple in color than flowers of plants of the female parent selection.
    • 3. Plants of the new Gaura have shorter peduncles than plants of the female parent selection.

Plants of the new Gaura can be compared to plants of Gaura lindheimeri ‘KLEGL06261’, not patented. In side-by-side comparisons, plants of the new Gaura differ from plants of ‘KLEGL06261’ in the following characteristics:

    • 1. Plants of the new Gaura have broader leaves than plants of ‘KLEGL06261’.
    • 2. Plants of the new Gaura have slightly larger flowers than plants of ‘KLEGL06261’.
    • 3. Flowers of plants of the new Gaura are brighter red purple in color than flowers of plants of ‘KLEGL06261’.

Plants of the new Gaura can be compared to plants of Gaura lindheimeri ‘Crimson Butterflies’, disclosed in U.S. Plant Pat. No. 13,189. In side-by-side comparisons, plants of the new Gaura differ from plants of ‘Crimson Butterflies’ in the following characteristics:

    • 1. Plants of the new Gaura are more compact than plants of ‘Crimson Butterflies’.
    • 2. Leaves of plants of the new Gaura are green in color whereas leaves of plants of ‘Crimson Butterflies’ are green to deep red in color.
    • 3. Plants of the new Gaura have shorter peduncles than plants of ‘Crimson Butterflies’.

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 compact than plants of ‘Florgaure’.
    • 2. Leaves of plants of the new Gaura are green in color whereas leaves of plants of ‘Florgaure’ are dark green to brown in color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate 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 photographs 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 on the first sheet is a side perspective view of a typical plant of ‘Summer Star Baby’ grown in a container.

The photograph on the second sheet is a close-up view of typical flowers of ‘Summer Star Baby’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring and early summer in 12-cm containers in an outdoor nursery in Boskoop, The Netherlands and under cultural practices typical of commercial Gaura production. During the production of the plants, day temperatures ranged from 15° C. to 28° C. and night temperatures ranged from 8° C. to 18° C. Plants were six months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
