Abstract

A new Dhalia plant particularly distinguished by its large, rose-colored flowers, good branching habit, and large, dark green leaves is disclosed.

Description

Genus and species: Dahlia variabilis.
Variety denomination: ‘Goalia Rossa’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct cultivar of Dhalia, botanically known as Dahlia variabilis, and hereinafter referred to by the cultivar name ‘Goalia Rossa’. The new cultivar originated from a hybridization made in June 1999 in Andijk, The Netherlands. The female parent was the bronze-yellow-flowered Dhalia proprietary line ‘DT-79-1’ (unpatented), and the male parent was the orange-flowered Dhalia proprietary line ‘DU-43-1’ (unpatented). The seeds produced by the hybridization were sown in February 2002 in Andijk, The Netherlands. A single plant selection was chosen for further evaluation and for asexual propagation in May 2002 in Andijk, The Netherlands.
The new cultivar was created in 1999 in Andijk, The Netherlands and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Andijk, The Netherlands, and Gilroy, Calif. over a five-year period. The plant has also been trialed at Gilroy, Calif. Michigan, Andijk, The Netherlands and Hillscheid, Germany. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.
Plant Breeder's Rights for this cultivar were applied for in the European Union on Jun. 19, 2006 and in Canada on Oct. 3, 2006. ‘Goalia Rossa’ has not been made publicly available more than one year prior to filing of this application.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Gilroy, Calif.
    • 1. Large, rose-colored flowers;
    • 2. Good branching habit; and
    • 3. Large, dark green leaves.
DESCRIPTION OF THE PHOTOGRAPHS
This new Dahlia plant is illustrated by the accompanying photographs which show overall plant habit including blooms, buds, and foliage of the plant; the photographs are of 20-to 24-week old plants grown in a greenhouse in Hillscheid, Germany in 2006; the colors shown are as true as can be reasonably obtained by conventional photographic procedures.
FIG. 1 shows a close-up of the mature flowers.
FIG. 2 shows the overall plant habit, including blooms, buds, and foliage.
 DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of ‘Goalia Rossa’. The data which define these characteristics were collected from asexual reproductions carried out in Ontario, Canada. The plant history was taken on 16-week-old plants grown in 6-inch azalea pots in the spring and summer seasons in a greenhouse. Two terminal pinches were made at a young plant stage. No plant growth regulators were used. The plants were grown under a poly covered hoop and then moved indoors. Color readings were taken outdoors in the summer season under natural light. Color references are primarily in the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition).
