Description

Botanical designation: Rudbeckia hirta×Echinacea purpurea.
Cultivar denomination: ‘ET-RDB 02’.
CROSS REFERENCED TO CLOSELY-RELATED APPLICATIONS
Title: Rudbeckia Plant Named ‘ET-RDB 01’
Applicant: Bart Noordhuis
U.S. Plant patent application Ser. No. 13/815,479.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Rudbeckia plant, botanically known as Rudbeckia hirta×Echinacea purpurea and hereinafter referred to by the name ‘ET-RDB 02’.
The new Rudbeckia plant is a product of a planned breeding program conducted by the Inventor in Boijl, The Netherlands. The objective of the breeding program is to create new compact Rudbeckia plants with small leaves and attractive long-lasting inflorescences.
The new Rudbeckia plant originated from a cross-pollination made by the Inventor in Boijl, The Netherlands in 2010 of a proprietary selection of Rudbeckia hirta identified as code number 7-357, not patented, as the female, or seed parent with a proprietary selection of Echinacea purpurea identified as code number 124-6, not patented, as the male, or pollen, parent. The new Rudbeckia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Boijl, The Netherlands in 2011.
Asexual reproduction of the new Rudbeckia by tissue culture in a controlled greenhouse environment in Boijl, The Netherlands since 2011 has shown that the unique features of this new Rudbeckia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Rudbeckia have not been observed under all possible 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-RDB 02’. These characteristics in combination distinguish ‘ET-RDB 02’ as a new and distinct Rudbeckia plant:
    • 1. Compact, upright to outwardly spreading and mounded plant habit.
    • 2. Freely branching growth habit.
    • 3 Relatively small leaves.
    • 4. Freely flowering habit.
    • 5. Single-type inflorescences with yellow, orange and reddish-colored ray florets and dark purple-colored disc florets positioned above the foliar plane on strong peduncles.
    • 6. Good postproduction longevity.
Plants of the new Rudbeckia differ from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Rudbeckia are more compact and denser than plants of the female parent selection.
    • 2. Inflorescences of plants of the new Rudbeckia are longer lasting than inflorescences of plants of the female parent selection.
Plants of the new Rudbeckia differ from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Rudbeckia are more compact and denser than plants of the male parent selection.
    • 2. Inflorescences of plants of the new Rudbeckia are longer lasting than inflorescences of plants of the male parent selection.
Plants of the new Rudbeckia can be compared to Rudbeckia hirta×Echinacea purpurea ‘ET-RDB 01’, disclosed in a U.S. Plant patent application Ser. No. 13/815,479. Plants of the new Rudbeckia differ primarily from plants of ‘ET-RDB 01’ in the following characteristics:
    • 1. Plants of the new Rudbeckia are taller than plants of ‘ET-RDB 01’.
    • 2. Plants of the new Rudbeckia have more ray florets per inflorescence than plants of ‘ET-RDB 01’.
    • 3. Plants of the new Rudbeckia and ‘ET-RDB 01’ differ in ray floret color.
Plants of the new Rudbeckia can also be compared to plants of Rudbeckia ‘Berlijn’, not patented. In side-by-side comparisons conducted in Boijl, The Netherlands, plants of the new Rudbeckia differed from plants of ‘Berlijn’ in the following characteristics:
    • 1. Plants of the new Rudbeckia were more compact than plants of ‘Berlijn’.
    • 2. Plants of the new Rudbeckia had smaller leaves than plants of ‘Berlijn’.
    • 3. Inflorescences of plants of the new Rudbeckia were longer lasting than inflorescences of plants of ‘Berlijn’.
    • 4. Plants of the new Rudbeckia had shorter and stronger peduncles than plants of ‘Berlijn’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Rudbeckia 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 Rudbeckia.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘ET-RDB 02’ grown in a container.
The photograph on the second sheet is a close-up view of typical inflorescences of ‘ET-RDB 02’.
 DETAILED BOTANICAL DESCRIPTION
