Abstract

A new and distinct cultivar of Astilbe plant named ‘Go Go Red’, characterized by its relatively compact and broadly upright plant habit; vigorous growth habit; dark green-colored leaves; freely and uniformly flowering habit; long flowering period; reddish purple-colored flowers on upright and strong peduncles; and good container and garden performance.

Description

Botanical designation: Astilbe chinensis X Astilbe arendsii.

Cultivar denomination: ‘GO GO RED’.

BACKGROUND OF THE INVENTION

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

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 2013 in Nieuwe Wetering, The Netherlands, of Astilbe chinensis ‘Harvandermeer’, not patented, as the female, or seed, parent with an unknown seedling selection of Astilbe arendsii 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 2015.

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

- 1. Relatively compact and broadly upright plant habit.
- 2. Vigorous growth habit.
- 3. Dark green-colored leaves.
- 4. Freely and uniformly flowering habit.
- 5. Long flowering period.
- 6. Reddish purple-colored flowers on upright and strong peduncles.
- 7. 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 more compact than plants of ‘Harvandermeer’.
- 2. Plants of the new Astilbe flower for a longer period of time than plants of ‘Harvandermeer’.

Plants of the new Astilbe can be compared to plants of Astilbe japonica ‘Red Sentinel’, not patented. In side-by-side comparisons, plants of the new Astilbe and ‘Red Sentinel’ differ primarily in the following characteristics:

- 1. Plants of the new Astilbe are more compact than plants of ‘Red Sentinel’.
- 2. Plants of the new Astilbe have smaller flowers than plants of ‘Red Sentinel’.
- 3. Plants of the new Astilbe flower for a longer period of time than plants of ‘Red Sentinel’.
- 4. Flowers of plants of the new Astilbe are lighter and brighter reddish purple in color than flowers of plants of ‘Red Sentinel’.

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 ) is a side perspective view of a typical flowering plant of ‘Go Go Red’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of typical inflorescences of ‘Go Go Red’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer in 15-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 18C to 34C and night temperatures ranged from 10C to 20C. 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 tetms of ordinary dictionary significance are used.
