Gaura lindheimerii plant named ‘Gauheha’

Abstract

A new and distinct Gaura lindheimeri plant with red-purple colored flowers, attractive variegated foliage, and a long blooming season.

Description

Botanical classification: Gaura lindheimeri.

Varietal denomination: ‘Gauheha’

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Gaura lindheimeri known by the varietal name ‘Gauheha’. The new variety was discovered and isolated in Niigata, Japan in May of 2002 as a naturally occurring branch mutation of Gaura lindheimeri ‘Gauchebra’ (U.S. Plant Pat. No. 14,581). The new variety exhibits similar flower color and flower habit to ‘Gauchebra’, but is different from ‘Gauchebra’ in the coloring of the foliage. The flower color, plant habit and foliage color of ‘Gauheha’ differ from other Gaura lindheimeri varieties known to the breeder. The new variety was first asexually reproduced by terminal cuttings in Niigata, Japan. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive asexual propagations.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 is a photograph of the new variety;

FIG. 2 is a photograph of the spike and flowers of the new variety;

FIG. 3 is a photograph of the flowers of the new variety; and

FIG. 4 is a photograph of the leaves of the new variety.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar grown outside in peat-based compost in 17 cm pots with no extra fertilizer in The Netherlands. The data which defines these characteristics was collected by asexual reproductions by cuttings. The color readings were taken in The Netherlands under natural daylight. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
