Abstract

A new and distinct cultivar of Astilbe plant named ‘Harvandermeerrubyred’, characterized by its tall, broadly upright and mounding plant habit; vigorous growth habit; dark green-colored leaves; freely and uniformly flowering habit; dark red purple-colored flowers on upright and strong peduncles; and good container and garden performance.

Description

Botanical designation: Astilbe chinensis.

Cultivar denomination: ‘HARVANDERMEERRUBYRED’.

BACKGROUND OF THE INVENTION

The present, invention relates to a new and distinct cultivar of Astilbe, botanically known as Astilbe chinensis and hereinafter referred to by the name ‘Harvandermeerrubyred’.

The new Astilbe plant is a product of a planned breeding program conducted by the Inventor in Nieuwe Wetering, 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 an open-pollination in 2011 in Nieuwe Wetering, The Netherlands, of Astilbe chinensis ‘Harvandermeer’, not patented, as the female, or seed, parent with an unknown Astilbe chinensis seedling selection 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 open-pollination in a controlled greenhouse environment in Nieuwe Wetering, The Netherlands during the summer of 2013.

Asexual reproduction of the new Astilbe plant by vegetative divisions in a controlled nursery environment in Nieuwe Wetering, The Netherlands since December, 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 ‘Harvandermeerrubyred’. These characteristics in combination distinguish ‘Harvandermeerrubyred’ as a new and distinct Astilbe plant:

    • 1. Tall, broadly upright and mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Dark green-colored leaves.
    • 4. Freely and uniformly flowering habit.
    • 5. Dark red purple-colored flowers on upright and strong peduncles.
    • 6. Good container and garden performance.

Plants of the new Astilbe differ primarily from plants of the female parent, ‘Harvandermeer’, in the following characteristics:

    • 1. Plants of the new Astilbe are taller than plants of ‘Harvandermeer’.
    • 2. Inflorescences of plants of the new Astilbe are larger than inflorescences of plants of ‘Harvandermeer’.
    • 3. Flowers of plants of the new Astilbe are dark red purple in color whereas flowers of plants of ‘Harvandermeer’ are dark pink in color.

Plants of the new Astilbe can be compared to plants of Astilbe chinensis ‘Vision in Red’, disclosed in U.S. Plant Pat. No. 11,965. In side-by-side comparisons, plants of the new Astilbe and ‘Vision in Red’ differ in the following characteristics:

    • 1. Plants of the new Astilbe are taller than plants of ‘Vision in Red’.
    • 2. Leaves of plants of the new Astilbe are darker green in color than leaves of plants of ‘Vision in Red’.
    • 3. Inflorescences of plants of the new Astilbe are larger than inflorescences of plants of ‘Vision in Red’.
    • 4. Flowers of plants of the new Astilbe are dark red purple in color whereas flowers of plants of ‘Vision in Red’ are purple 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 is a side perspective view of a typical flowering plant of ‘Harvandermeerrubyred’ grown in a container.

The photograph on the second sheet is a close-up view of typical inflorescences of ‘Harvandermeerrubyred’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and early summer in 19-cm containers in an outdoor nursery in Nieuwe Wetering, The Netherlands and under cultural practices typical of commercial Astilbe production. During the production of the plants, day temperatures ranged from 25° C. to 30° C. and night temperatures ranged from 15° C. to 20° 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.
