Abstract

A distinct cultivar of Dahlia plant named `Fleurel`, characterized by its large fully double pure white inflorescences and relatively compact growth habit.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of Dahlia plant, botanically known as Dahlia hybrida, and hereinafter referred to by the name `Fleurel`.
The new Dahlia is a naturally-occurring mutation of the yellow-flowered Dahlia hybrida `Kelvin Floodlight` (not patented). In August, 1994, the new Dahlia was discovered by the inventor in a controlled environment in Zwaanshoek, The Netherlands, within a population of plants of `Kelvin Floodlight`. The selection of this plant was based on its large white double flowers and compact plant habit.
Asexual reproduction of the new Dahlia by tubers or cuttings harvested at a controlled environment in Zwaanshoek, The Netherlands, has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.
BRIEF SUMMARY OF THE INVENTION
The new Dahlia 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 `Fleurel`. These characteristics in combination distinguish `Fleurel` as a new and distinct cultivar:
1. Large fully double pure white inflorescences.
2. Relatively compact growth habit.
The new Dahlia 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.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The photograph on the first sheet comprises a close-up view of a typical inflorescence of the new Dahlia.
The top photograph on the second sheet comprises a close-up view of typical ray florets of `Fleurel`.
The lower photograph on the second sheet comprises a close-up view of compound leaves (left) and single leaves (right). Floret and foliage colors may appear different from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown outdoors in Zwaanshoek, The Netherlands, during the summer under commercial practice after storing tubers at 5 to 9° C. from the end of October to January.
