Abstract
A new and distinct variety of Gaura plant, substantially as herein illustrated and described, characterized particularly as to novelty by a well-branched, compact habit, continuous flowering, pink flowers, green foliage and early to flower.
Description
LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED


Gaura lindheimeri


VARIETAL DENOMINATION

‘Gaudros’


BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct Gaura plant, botanically known as Gaura lindheimeri, and hereinafter referred to by the cultivar name ‘Gaudros.’


The new cultivar was developed by the inventor in a controlled breeding program during 2000, at Enkhuizen, The Netherlands. The new Gaura cultivar is characterized by a well-branched, compact habit, continuous flowering, green foliage and early to flower.


The female (seed) parent of ‘Gaudros’ was ‘B0012-1,’ an unpatented proprietary inbred line that is not known by any synonyms. The male (pollen) parent of ‘Gaudros’ was ‘C0013-1,’ also a proprietary inbred line that is not known by any synonyms. ‘Gaudros’ was selected in May 2001 as a single flowering plant from within the F2 progeny of the above stated cross and was initially designated ‘D0010-1.’


Asexual reproduction of the new cultivar at Enkhuizen, The Netherlands and Sarrians, France was carried out by the use of terminal stem cuttings, and has demonstrated that the new variety is stable and reproduces true to type in successive generations of asexual reproduction.


SUMMARY OF THE INVENTION

It was found that the cultivar of the present invention:

    • a) Exhibits pink flowers;
    • b) Forms green foliage; and
    • c) Exhibits an upright and very well branched growth habit




DESCRIPTION OF THE DRAWING

This new Gaura plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures.




DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new Gaura. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 16 weeks old plants blossomed under natural light in a greenhouse and grown in a 13 cm container.


Color readings were taken in the greenhouse under ambient light. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London.
