Description

Botanical designation: Astilbe hybrida.

Cultivar denomination: ‘LITTLE VISION IN PINK’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Astilbe plant, botanically known as Astilbe hybrida and hereinafter referred to by the name ‘Little Vision in Pink’.

The new Astilbe plant is a product of a planned breeding program conducted by the Inventor in Noorden, The Netherlands. The objective of the breeding program was to create new compact and strong Astilbe plants with attractive foliage and flower coloration.

The new Astilbe plant originated from a cross-pollination made by the Inventor in 2004 in Noorden, The Netherlands, of an unnamed proprietary seedling of Astilbe chinensis×Astilbe arendsii, not patented, as the female, or seed, parent with Astilbe chinensis ‘Vision In Pink’, disclosed in U.S. Plant Pat. No. 11,860, as the male, or pollen, parent. The new Astilbe plant 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 in Noorden, The Netherlands in 2006.

Asexual reproduction of the new Astilbe plant by divisions in a controlled environment in Noorden, The Netherlands since January, 2007, 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 environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Little Vision in Pink’. These characteristics in combination distinguish ‘Little Vision in Pink’ as a new and distinct cultivar of Astilbe:

    • 1. Compact, upright and strong plant habit.
    • 2. Strong, healthy and dark-colored foliage.
    • 3. Freely and uniformly flowering habit with narrow inflorescences positioned above the foliar plane.
    • 4. Dark pink-colored flowers.
    • 5. Good garden performance.

Plants of the new Astilbe differ primarily from plants of the female parent selection in the following characteristics:

    • 1. Plants of the new Astilbe are more compact than plants of the female parent selection.
    • 2. Plants of the new Astilbe have stronger stems than plants of the female parent selection.
    • 3. Plants of the new Astilbe have darker-colored flowers than plants of the female parent selection.

Plants of the new Astilbe differ primarily from plants of the male parent, ‘Vision In Pink’, in the following characteristics:

    • 1. Plants of the new Astilbe are more compact than plants of ‘Vision In Pink’.
    • 2. Inflorescences of plants of the new Astilbe are positioned higher above the foliar plane than inflorescences of plants of ‘Vision In Pink’.
    • 3. Plants of the new Astilbe have darker-colored flowers than plants of ‘Vision In Pink’.

Plants of the new Astilbe can be compared to plants of Astilbe chinensis ‘Vision’, not patented. In side-by-side comparisons conducted in Noorden, The Netherlands, plants of the new Astilbe differed from plants of ‘Vision’ in the following characteristics:

    • 1. Plants of the new Astilbe were more compact than plants of ‘Vision’.
    • 2. Leaves of plants of the new Astilbe were finer than leaves of plants of ‘Vision’.
    • 3. Plants of the new Astilbe had darker-colored flowers than plants of ‘Vision’.
