Abstract

A distinct cultivar of Delphinium plant name ‘Darwin's Blue Indulgence’, characterized by its upright plant habit; freely flowering habit; and double blue-colored flowers.

Description

BOTANICAL CLASSIFICATION
Delphinium elatum.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Delphinium plant, botanically known as Delphinium elatum, and hereinafter referred to by the name ‘Darwin's Blue Indulgence’.
The new Delphinium was discovered by the Inventor in a controlled environment in Abbenes, The Netherlands, as a naturally-occurring mutation of an unidentified selection of Delphinium elatum. The new Delphinium was selected by the Inventor on the basis of its double blue-colored flowers.
Asexual reproduction of the new cultivar by cuttings in a controlled environment in Hillegom, The Netherlands, since 1999, has shown that the unique features of this new Delphinium are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Darwin's Blue Indulgence have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, irrigation amount and frequency, and/or fertilizer type or rate without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Darwin's Blue Indulgence’. These characteristics in combination distinguish ‘Darwin's Blue Indulgence’ as a new and distinct cultivar:
1. Upright plant habit.
2. Freely flowering habit.
3. Double blue-colored flowers.
Plants of the cultivar Darwin's Blue Indulgence differ from the parent selection and other known cultivars of Delphinium in its double flower form and flower color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Delphinium, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Delphinium.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Darwin's Blue Indulgence’.
The photograph at the top of the second sheet is a close-up view of typical flowers of ‘Darwin's Blue Indulgence’.
The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical leaf of ‘Darwin's Blue Indulgence’.
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. Plants used for the photographs and the following description were about 30 weeks old and grown under field conditions which closely approximate commericial production conditions during the spring and summer in Hillegom, The Netherlands.
