Abstract

A new and distinct cultivar of Astilbe plant named ‘Whiteberry’, characterized by its compact, broadly upright and mounding plant habit; strong and durable leaves; freely and uniformly flowering habit; white-colored flowers on strong greyed orange-colored peduncles; and good container and garden performance.

Description

Botanical designation: Astilbe arendsii X Astilbe japonica.
Cultivar denomination: ‘WHITEBERRY’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Astilbe, botanically known as Astilbe arendsii X Astilbe japonica and hereinafter referred to by the name ‘Whiteberry’.
The new Astilbe plant is a product of a planned breeding program conducted by the Inventor in Haarlem, 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 made by the Inventor in 2010 in Haarlem, The Netherlands, of an unnamed Astilbe arendsii seedling selection, not patented, as the female, or seed, parent with an unnamed Astilbe japonica seedling selection, 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 Haarlem, The Netherlands in 2013.
Asexual reproduction of the new Astilbe plant by vegetative divisions in a controlled nursery environment in Heerhugowaard, The Netherlands since the summer of 2013, 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 ‘Whiteberry’. These characteristics in combination distinguish ‘Whiteberry’ as a new and distinct Astilbe plant:
    • 1. Compact, broadly upright and mounding plant habit.
    • 2. Strong and durable leaves.
    • 3. Freely and uniformly flowering habit.
    • 4. White-colored flowers on strong greyed orange-colored peduncles.
    • 5. Good container and garden performance.
Plants of the new Astilbe differ primarily from plants of the parent selections in plant height and flowering habit as plants of the new Astilbe are more compact and more freely flowering than plants of the parent selections.
Plants of the new Astilbe can be compared to plants of Astilbe japonica ‘Washington’, not patented. In side-by-side comparisons, plants of the new Astilbe and ‘Washington’ differ in the following characteristics:
    • 1. Plants of the new Astilbe are more compact than plants of ‘Washington’.
    • 2. Plants of the new Astilbe have better container performance than plants of ‘Washington’.
    • 3. Plants of the new Astilbe are more freely flowering than plants of ‘Washington’.
    • 4. Plants of the new Astilbe and ‘Washington’ differ in peduncle color as plants of ‘Washington’ have green-colored peduncles.
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 is a side perspective view of a typical flowering plant of ‘Whiteberry’ grown in a container.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Whiteberry’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the summer and early autumn in 21-cm containers in an outdoor nursery in Haarlem, The Netherlands and under cultural practices typical of commercial Astilbe production. During the production of the plants, day temperatures ranged from 16° C. to 32° C. and night temperatures ranged from 6° C. to 18° C. Plants were one year old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
