USPP16981P2 - Gaura lindheimerii plant named ‘Gausudre’ - Google Patents

Abstract

A new and distinct Gaura lindheimerii plant with a compact growth habit, large deep rose colored flowers, and a long blooming season.

Description

Botanical classification: Gaura lindheimerii.

Varietal denomination: ‘Gausudre’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Gaura lindheimerii known by the varietal name ‘Gausudre’. The new variety originated in a planned breeding program in The Netherlands as a result of cross breeding Gaura ‘Siskyou Pink’ (female parent, unpatented) and an unnamed short form Gaura (male parent, unpatented). The new variety is more compact and exhibits more free branching and a deeper flower color than both parents, which met the goals of the breeding program. The large and uniformly colored flowers of ‘Gausudre’ differ from other Gaura lindheimerii varieties known to the breeder. The new variety was first asexually reproduced by rooted terminal tip cuttings in The Netherlands. 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 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 close-up photograph of the new variety; and

FIG. 3 is a close-up photograph of the flowers 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.
