Abstract

A distinct cultivar of Delphinium plant named ‘Delft Blue’, characterized by its upright plant habit; freely flowering habit; and blue and light blue bi-colored flowers.

Description

Botanical classification/cultivar designation: Delphinium belladona cultivar Delft Blue.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Delphinium plant, botanically known as Delphinium belladona, and hereinafter referred to by the name ‘Delft Blue’.
The new Delphinium was discovered by the Inventor in 1999 in a controlled environment in Noordwijkerhout, The Netherlands, as a naturally-occurring whole plant mutation of the Delphinium belladona cultivar Volkerfrieden, not patented. The new Delphinium was selected by the Inventor on the basis of its unique blue and light blue bi-colored flowers.
Asexual reproduction of the new Delphinium by cuttings in a controlled environment in Noordwijkerhout, The Netherlands, since 2000, 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 Delft Blue have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature 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 ‘Delft Blue’. These characteristics in combination distinguish ‘Delft Blue’ as a new and distinct cultivar:
1. Upright plant habit.
2. Freely flowering habit.
3. Blue and light blue bi-colored flowers.
Plants of the cultivar Delft Blue differ from the parent cultivar, Volkerfrieden and other Delphinium cultivars known to the Inventor in its unique flower coloration.
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 ‘Delft Blue’ grown in a container.
The photograph at the top of the second sheet is a close-up view of typical flowers of ‘Delft Blue’.
The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical leaf of ‘Delft Blue’.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
