Abstract

A distinct cultivar of Dahlia plant named ‘Patricia’, characterized by its upright plant habit; freely branching habit; semi-double type inflorescences; and light orange and red bi-colored ray florets.

Description

Botanical classification/cultivar designation: Dahlia variabilis cultivar Patricia.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia variabilis, commercially referred to as a pot-type Dahlia, and hereinafter referred to by the cultivar name ‘Patricia’.
The new Dahlia is a naturally-occurring branch sport of the Dahlia cultivar Connie, disclosed in U.S. Plant Pat. No. 6,768. The new Dahlia was discovered by the Inventor in a controlled environment in Arroyo Grande, Calif. in April, 1997.
Asexual reproduction of the new Dahlia by stem cuttings was first conducted in Arroyo Grande, Calif. in 1997. Asexual reproduction by cuttings has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Patricia has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and daylength, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Patricia’. These characteristics in combination distinguish ‘Patricia’ as a new and distinct pot-type Dahlia:
1. Upright plant habit.
2. Freely branching habit.
3. Semi-double type inflorescences.
4. Light orange and red bi-colored ray florets.
Plants of the new Dahlia differ from plants of the parent, the cultivar Connie, primarily in ray floret coloration as plants of the cultivar Connie have bright orange red-colored ray florets.
Plants of the new Dahlia can be compared to plants of the Dahlia cultivar Margaret, disclosed in U.S. Plant Pat. No. 6,769. In side-by-side comparisons conducted in West Chicago, Ill., plants of the new Dahlia had larger leaves and were more freely branching than plants of the cultivar Margaret. In addition, plants of the new Dahlia and the cultivar Margaret differed in ray floret color as plants of the cultivar Margaret had bright yellow-colored ray florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Dahlia showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Dahlia.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Patricia’.
The photograph at the bottom of the sheet is a close-up view of a typical inflorescence of ‘Patricia’.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown and flowered during the spring in West Chicago, Ill., under commercial practice in a polycarbonate-covered greenhouse. During the production the plants, day temperatures ranged from 18 to 24° C., night temperatures ranged from 16 to 18° C., and light levels ranged from 4,000 to 6,000 footcandles. One cutting was planted per 10-cm container and plants were grown for about 12 weeks.
