A new and distinct cultivar of Delphinium plant named ‘ET DLP 824’, characterized by its relatively compact, upright and sturdy plant habit; relatively short internodes; dark green-colored leaves; freely flowering habit; moderately strong to strong flowering stems with dense inflorescences with numerous white-colored flowers; and good garden performance.

Description

Botanical designation: Delphinium elatum X (Delphinium x belladonna).
Cultivar denomination: ‘ET DLP 824’.
CROSS-REFERENCED TO A RELATED APPLICATION & STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTORS/APPLICANTS
This application claims priority to a European Community Plant Breeders' Rights application filed on Oct. 1, 2021, application number 2021/2441. There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed Plant Breeder's Rights documents.
The Inventors/Applicants assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventors/Applicants. Inventors/Applicants claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Delphinium plant, botanically known as Delphinium elatum X (Delphinium x belladonna), typically grown as a perennial garden plant and hereinafter referred to by the name ‘ET DLP 824’.
The new Delphinium plant is a product of a planned breeding program conducted by the Inventors in Boijl, The Netherlands. The objective of the breeding program is to create new strong and freely-flowering Delphinium plants with dense inflorescences and unique and attractive flower colors.
The new Delphinium plant originated from a cross-pollination in July, 2014 of a proprietary selection of Delphinium elatum identified as code number 9-88, not patented, as the female, or seed, parent with a proprietary selection of Delphinium x belladonna identified as code number 102, not patented, as the male, or pollen, parent. The new Delphinium plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Boijl, The Netherlands in July, 2016.
Asexual reproduction of the new Delphinium plant by in vitro meristem culture in a controlled environment in Boijl, The Netherlands, since August, 2017 has shown that the unique features of this new Delphinium plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Delphinium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘ET DLP 824’. These characteristics in combination distinguish ‘ET DLP 824’ as a new and distinct Delphinium plant:
    • 1. Relatively compact, upright and sturdy plant habit.
    • 2. Relatively short internodes.
    • 3. Dark green-colored leaves.
    • 4. Freely flowering habit.
    • 5. Moderately strong to strong flowering stems with dense inflorescences with numerous white-colored flowers.
    • 6. Good garden performance.
Plants of the new Delphinium differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Delphinium are more compact and shorter than plants of the female parent selection.
    • 2. Flowers of plants of the new Delphinium are white in color whereas flowers of plants of the female parent selection are yellowish white in color.
Plants of the new Delphinium differ primarily from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Delphinium are taller than plants of the male parent selection.
    • 2. Plants of the new Delphinium have larger flowers than plants of the male parent selection.
    • 3. Flowers of plants of the new Delphinium are white in color whereas flowers of plants of the male parent selection are purple in color.
Plants of the new Delphinium can be compared to plants of Delphinium elatum X (Delphinium belladona) ‘ET DLP 17-10’, disclosed in U.S. Plant Pat. No. 32,993. In side-by-side comparisons, plants of the new Delphinium differ primarily from plants of ‘ET DLP 17-10’ in the following characteristics:
    • 1. Plants of the new Delphinium are taller than plants of ‘ET DLP 17-10’.
    • 2. Plants of the new Delphinium have slightly smaller flowers than plants of ‘ET DLP 17-10’.
    • 3. Flowers of plants of the new Delphinium are white in color whereas flowers of plants of ‘ET DLP 17-10’ are purple violet in color.
Plants of the new Delphinium can be compared to plants of Delphinium elatum ‘Flamingo Star’, not patented. In side-by-side comparisons, plants of the new Delphinium differ primarily from plants of ‘Flamingo Star’ in the following characteristics:
    • 1. Plants of the new Delphinium are more compact than plants of ‘Flamingo Star’.
    • 2. Plants of the new Delphinium have stronger flowering stems than plants of ‘Flamingo Star’.
    • 3. Flowering stems of plants of the new Delphinium are branching whereas flowering stems of plants of ‘Flamingo Star’ are not branching.
    • 4. Flowers of plants of the new Delphinium are white in color whereas flowers of plants of ‘Flamingo Star’ are pink in color.
