Abstract: A new and distinct cultivar of Astilbe plant named `Verssalmon`, characterized by its compact, upright and strong plant habit; strong and healthy foliage; freely and uniformly flowering habit; light salmon pink-colored flowers; and good garden performance.
Claim: It is claimed:

1. A new and distinct Astilbe plant named `Verssalmon` as illustrated and described.
Description: Botanical designation: Astilbearendsii.times.Astilbe japonica.

Cultivar denomination: `Verssalmon`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Astilbe, botanically known as Astilbe arendsii.times.Astilbe japonica and hereinafter referred to by the name `Verssalmon`.

The new Astilbe 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 strong Astilbe cultivars with attractive foliage and flower coloration.

The new Astilbe originated from a cross-pollination made by the Inventor in 2001 in Haarlem, The Netherlands, of an unnamed Astilbe arendsii seedling selection, not patented, as the female, or seed, parent with an unnamed Astilbe japonicaseedling selection, not patented, as the male, or pollen, parent. The new Astilbe was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment inHaarlem, The Netherlands in 2003.

Asexual reproduction of the new Astilbe by divisions in a controlled environment in a greenhouse in Honselersdijk, The Netherlands since 2003, has shown that the unique features of this new Astilbe are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

The cultivar `Verssalmon` has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, anyvariance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Verssalmon`. These characteristics in combination distinguish `Verssalmon` as a new and distinct cultivar of Astilbe: 1. Compact, uprightand strong plant habit. 2. Strong and healthy foliage. 3. Freely and uniformly flowering habit. 4. Light salmon pink-colored flowers. 5. Good 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 the Astilbe arendsii cultivar Federsee, not patented. In side-by-side comparisons conducted in Haarlem, The Netherlands, plants of the new Astilbe and the cultivar Federsee differed in thefollowing characteristics: 1. Plants of the new Astilbe were more compact than plants of the cultivar Federsee. 2. Plants of the new Astilbe flowered earlier than plants of the cultivar Federsee. 3. Plants of the new Astilbe were more freelyflowering than plants of the cultivar Federsee.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Astilbe, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Astilbe.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of `Verssalmon` grown in a container.

The photograph at the top of the second sheet is a close-up view of typical inflorescences of `Verssalmon`.

The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical leaf of `Verssalmon`.
