Dahlia plant named ‘Goalia Scarl’

Abstract

A new Dhalia plant particularly distinguished by its large scarlet flowers, a full plant habit, and small, dark green leaves foliage is disclosed.

Description

Genus and species: Dahlia variabilis.

Variety denomination: ‘Goalia Scarl’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Dahlia, botanically known as Dahlia variabilis, and hereinafter referred to by the cultivar name ‘Goalia Scarl’. The new cultivar originated from a hybridization made in June 1999 in Andijk, The Netherlands. The female parent was the bronze-yellow-flowered Dahlia proprietary line ‘DT-32-2’ (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 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 Canada on Oct. 3, 2006. ‘Goalia Scarl’ 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, scarlet flowers;
  • 2. A full plant habit; and
  • 3. Small, 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 Hillschied, 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 Scarl’. 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 indoor. Color readings were taken outdoors in the summer season under natural light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition).
