Abstract

A new and distinct cultivar of Dahlia plant named ‘Carolina Burgundy’, characterized by its upright, uniformly mounded and compact plant habit; freely branching, full and dense plants; short response time; and dark red purple-colored ray florets with bright yellow-colored disc florets.

Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION
Dahlia variabilis cultivar Carolina Burgundy.
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 name ‘Carolina Burgundy’.
The new Dahlia is a naturally-occurring whole plant mutation of the Dahlia variabilis cultivar Ruicaro, disclosed in U.S. Plant Pat. No. 11,566. The new Dahlia was discovered and selected in 1997 by the Inventor as a single flowering plant within a population of plants of the cultivar Ruicaro in a controlled environment in Hillegom, The Netherlands. The selection of this plant was based on its dark red purple-colored ray florets.
Asexual reproduction of the new Dahlia by vegetative tip cuttings was first conducted in Hillegom, The Netherlands in 1998. 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 Carolina Burgundy has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Carolina Burgundy’. These characteristics in combination distinguish ‘Carolina Burgundy’ as a new and distinct pot-type Dahlia:
1. Upright, uniformly mounded and compact plant habit.
2. Freely branching, full and dense plants.
3. Short response time.
4. Dark red purple-colored ray florets with bright yellow-colored disc florets.
Plants of the new Dahlia differ from plants of the parent cultivar Ruicaro and the cultivar Carolina Orange, U.S. Plant Patent application Ser. No. 10/080,606 filed concurrently, primarily in ray floret coloration.
Plants of the new Dahlia can be compared to plants of the cultivar Maryland, disclosed in U.S. Plant Pat. No. 11,602. However, in side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Dahlia differed from plants of the cultivar Maryland in the following characteristics:
1. Plants of the new Dahlia flower about one to two weeks earlier than plants of the cultivar Maryland.
2. Plants of the new Dahlia had smaller leaves than plants of the cultivar Maryland.
3. Plants of the new Dahlia had smaller inflorescences than plants of the cultivar Maryland.
4. Plants of the new Dahlia and plants of the cultivar Maryland differed in ray floret coloration.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates 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 photograph may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Dahlia.
The photograph comprises a side perspective view of a typical flowering plant of ‘Carolina Burgundy’.
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. Plants used in the aforementioned photographs, and the following observations and measurements were grown and flowered during the autumn in a glass-covered greenhouse in De Lier, The Netherlands. One rooted cutting was planted in a 10.5-cm container and pinched one week after planting. During the production of these plants, the day temperature ranged from 19 to 21° C., night temperatures ranged from 18 to 20° C., and light levels ranged from 10,000 to 15,000 lux. Measurements and numerical values represent averages of typical flowering plants about eight weeks after planting.
