plant named ‘Harrosy’

Abstract

A new cultivar of Gaura lindheimeri, ‘HARROSY’, characterized by its flowers that emerge from crimson red buds and have flower petals that are white in color with pink margins.

Description

Botanical classification: Gaura lindheimeri.

Cultivar designation: ‘HARROSY’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gaura plant, botanically known as Gaura lindheimeri ‘HARROSY’ and will be referred to hereafter by its cultivar name, ‘HARROSY’.

The Inventors discovered the new cultivar, ‘HARROSY’ as a branch mutation of Gaura lindheimeri ‘Siskiyou Pink’ (not patented) in a garden plot at their nursery in Whitchurch, Hants, United Kingdom in summer of 2006.

Asexual reproduction of the new cultivar was first accomplished by softwood stem cuttings in Whitchurch, Hants, United Kingdom in 2006 under the direction of the Inventors. Propagation has determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of ‘HARROSY’. These attributes in combination distinguish ‘HARROSY’ as a new and distinct cultivar of Gaura.

• • 1. ‘HARROSY’ exhibits flowers that have petals that are white in color with pink margins.
  • 2. ‘HARROSY’ exhibits flower buds that are crimson red in color.

‘HARROSY’ can be most closely compared to its parent plant, ‘Siskiyou Pink’. ‘Siskiyou Pink’ differs from ‘HARROSY’ in having flowers with petals that are pink in color rather than white with pink margins as observed for ‘HARROSY’. ‘HARROSY’ can also be compared to plants of the species, Gaura lindheimeri, which differ from ‘HARROSY’ in having white flowers and to the cultivar ‘Sunny Butterflies’ (not patented), which differs from ‘HARROSY’ in having flower petals that are pink in color with a white edge.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Gaura. The photographs were taken of six month-old plants of ‘HARROSY’ as grown outdoors in 12-cm containers in Whitchurch, Hants, United Kingdom.

The photograph in FIG. 1 is a view of flowering stems of ‘HARROSY’.

The photograph in FIG. 2 provides a close-up view of a flower of ‘HARROSY’ while

the photograph in FIG. 3 provides a view of flowers and flower buds of ‘HARROSY’. The colors in the photographs are as close as possible with digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Gaura.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of six month-old plants of the new cultivar as grown outdoors in 12-cm containers in full sun in Whitchurch, Hants, United Kingdom. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
