USPP16120P2 - Gaura plant named ‘Perky Pink’ - Google Patents

Abstract

A new and distinct cultivar of Gaura plant named ‘Perky Pink’, characterized by its compact and outwardly spreading plant habit; freely branching growth habit; freely flowering habit; and light pink-colored flowers.

Description

Botanical classification/cultivar designation: Gaura lindheimeri cultivar Perky Pink.

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 cultivar name Perky Pink.

The new Gaura is a product of a planned breeding program conducted by the Inventor in Narre Warren East, Victoria, Australia. The objective of the breeding program is to create new compact Gauras with numerous flowers and attractive flower coloration.

The new Gaura originated from a open-pollination made by the Inventor in 1999 of the Gaura lindheimeri cultivar Siskiyou Pink, not patented, as the female, or seed, parent with an unknown selection of Gaura lindheimeri, not patented, as the male, or pollen, parent. The new Gaura was selected as a single plant from the resulting progeny of the open-pollination by the Inventor in 2000 in a controlled environment in Narre Warren East, Victoria, Australia.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Narre Warren East, Victoria, Australia since October, 2000, has shown that the unique features of this new Gaura are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Perky Pink have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Perky Pink’. These characteristics in combination distinguish ‘Perky Pink’ as a new and distinct cultivar of Gaura:

• • 1. Compact and outwardly spreading plant habit.
  • 2. Freely branching growth habit.
  • 3. Freely flowering habit.
  • 4. Light pink-colored flowers.

Plants of the new Gaura can be compared to plants of the female parent, the cultivar Siskiyou Pink. In side-by-side comparisons conducted in Narre Warren East, Victoria, Australia, plants of the new Gaura differed from plants of the cultivar Siskiyou Pink in the following characteristics:

• • 1. Plants of the new Gaura were more compact and bushier than plants of the cultivar Siskiyou Pink.
  • 2. Plants of the new Gaura had darker colored foliage than plants of the cultivar Siskiyou Pink.
  • 3. Plants of the new Gaura and the cultivar Siskiyou Pink differed in flower color as plants of the cultivar Siskiyou Pink had red and white-colored flowers.

Plants of the new Gaura can also be compared to plants of other nonpatented selections of Gaura lindheimeri known to the Inventor. In side-by-side comparisons conducted in Narre Warren East, Victoria, Australia, plants of the new Gaura differed from plants of other known selections of Gaura lindheimeri known to the Inventor in the following characteristics:

• • 1. Plants of the new Gaura were more compact and bushier than plants of other known selections of Gaura lindheimeri known to the Inventor.
  • 2. Plants of the new Gaura had darker colored foliage than plants of other known selections of Gaura lindheimeri known to the Inventor.
  • 3. Plants of the new Gaura and other known selections of Gaura lindheimeri known to the Inventor differed in flower color as plants of other known selections of Gaura lindheimeri known to the Inventor had white-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Perky Pink’ grown in a container.

The photograph at the bottom of the sheet comprises a close-up view of typical flowers of ‘Perky Pink’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Bonsall, Calif., under full sun conditions in an outdoor nursery during the spring and summer with day temperatures ranging from 18 to 35° C. and night temperatures ranging from 10 to 18° C. Three plants were grown in a 15-cm container and had been growing for about six weeks when the photographs and description were taken.
