Description

Botanical designation: Astilbe arendsii X Astilbe chinensis.
Cultivar denomination: ‘RAZZLE DAZZLE’.
CROSS-REFERENCE TO A RELATED APPLICATION AND STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT
This application claims priority to a European Community Plant Breeders' Rights application filed on Feb. 1, 2020, application number 20200351. 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 Inventor/Applicant asserts 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 Inventor. Applicant claims a prior art exemption 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 Astilbe, botanically known as Astilbe arendsii X Astilbe chinensis and hereinafter referred to by the name ‘Razzle Dazzle’.
The new Astilbe plant is a product of a planned breeding program conducted by the Inventor in Heemskerk, The Netherlands. The objective of the breeding program was to create new uniform and freely flowering Astilbe plants with attractive leaf and flower coloration.
The new Astilbe plant originated from a cross-pollination in 2013 in Heemskerk, The Netherlands, of an unidentified seedling selection of Astilbe arendsii, not patented, as the female, or seed, parent with an unidentified seedling selection of Astilbe chinensis, not patented, as the male, or pollen, parent. The new Astilbe 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 greenhouse environment in Heemskerk, The Netherlands during the summer of 2015.
Asexual reproduction of the new Astilbe plant by vegetative divisions in a controlled nursery environment in Heemskerk, The Netherlands since December, 2015, has shown that the unique features of this new Astilbe plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Astilbe 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 ‘Razzle Dazzle’. These characteristics in combination distinguish ‘Razzle Dazzle’ as a new and distinct Astilbe plant:
    • 1. Broadly upright and mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Dense and bushy appearance.
    • 4. Dark green-colored leaves.
    • 5. Freely and uniformly flowering habit.
    • 6. Light and dark pink-colored flowers on strong, tall and upright peduncles.
    • 7. Good container and garden performance.
Plants of the new Astilbe differ primarily from plants of the selections in plant habit as plants of the new Astilbe are more compact than plants of the parent selections. In addition, plants of the new Astilbe are more freely flowering than plants of the parent selections.
Plants of the new Astilbe can be compared to plants of Astilbe arendsii ‘Bressingham Ruby’, not patented. In side-by-side comparisons, plants of the new Astilbe and ‘Bressingham Ruby’ differ primarily in the following characteristics:
    • 1. Plants of the new Astilbe are more compact and bushier than plants of ‘Bressingham Ruby’.
    • 2. Inflorescences of plants of the new Astilbe are smaller than inflorescences of plants of ‘Bressingham Ruby’.
    • 3. Flowers of plants of the new Astilbe are light pink and dark pink in color than flowers of plants of ‘Bressingham Ruby’ which are solid pink in color.
Plants of the new Astilbe can be compared to plants of Astilbe chinensis ‘Vision in Pink’, disclosed in U.S. Plant Pat. No. 11,860. In side-by-side comparisons, plants of the new Astilbe and ‘Vision in Pink’ differ primarily in the following characteristics:
    • 1. Plants of the new Astilbe are more compact and bushier than plants of ‘Vision in Pink’.
    • 2. Inflorescences of plants of the new Astilbe are smaller than inflorescences of plants of ‘Vision in Pink’.
    • 3. Flowers of plants of the new Astilbe are light and dark pink in color whereas flowers of plants of ‘Vision in Pink’ are solid pink in color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Astilbe plant 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 Astilbe plant.
The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘Razzle Dazzle’ grown in a container.
The photograph on the second sheet (FIG. 2 of 2) is a close-up view of typical inflorescences of ‘Razzle Dazzle’.
 DETAILED BOTANICAL DESCRIPTION
