Abstract

A new and distinct cultivar of Astrantia plant named ‘Pisa’, characterized by its upright plant habit with long flowering stems; freely-branching habit; freely and continuous flowering habit; long flowering period; inflorescences with showy involucral bracts that are white in color; and good garden performance.

Description

Botanical designation: Astrantia major.
Cultivar denomination: ‘PISA’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Astrantia plant, botanically known as Astrantia major and hereinafter referred to by the name ‘Pisa’.
The new Astrantia plant is a product of a planned breeding program conducted by the Inventor in Lisserbroek, The Netherlands. The objective of the breeding program is to create new freely branching Astrantia plants with large and attractive flowers.
The new Astrantia plant originated from a self-pollination during the summer of 2011 of Astrantia major ‘Snow Star’, disclosed in U.S. Plant Pat. No. 12,697. The new Astrantia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination grown in a controlled environment in Lisserbroek, The Netherlands during the summer of 2012.
Asexual reproduction of the new Astrantia plant by divisions in Lisserbroek, The Netherlands since 2014 has shown that the unique features of this new Astrantia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Astrantia 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 ‘Pisa’. These characteristics in combination distinguish ‘Pisa’ as a new and distinct Astrantia plant:
    • 1. Upright plant habit with long flowering stems.
    • 2. Freely-branching habit.
    • 3. Freely and continuous flowering habit; long flowering period.
    • 4. Inflorescences with showy involucral bracts that are white in color.
    • 5. Good garden performance.
Plants of the new Astrantia differ from plants of the parent, ‘Snow Star’, primarily in the following characteristics:
    • 1. Plants of the new Astrantia are more freely-branching than plants of ‘Snow Star’.
    • 2. Plants of the new Astrantia have larger inflorescences than plants of ‘Snow Star’.
    • 3. Inflorescences of plants of the new Astrantia have longer postproduction longevity than inflorescences of plants of ‘Snow Star’.
Plants of the new Astrantia can be compared to plants of Astrantia major ‘Alba’, not patented. In side-by-side comparisons conducted by the Inventor in Lisserbroek, The Netherlands, plants of the new Astrantia differed primarily from plants of ‘Alba’ in the following characteristics:
    • 1. Plants of the new Astrantia were more freely-branching than plants of ‘Alba’.
    • 2. Plants of the new Astrantia had longer flowering stems than plants of ‘Alba’.
    • 3. Plants of the new Astrantia had larger inflorescences than plants of ‘Alba’.
Plants of the new Astrantia can also be compared to plants of Astrantia major ‘Shaggy’, not patented. In side-by-side comparisons conducted by the Inventor in Lisserbroek, The Netherlands, plants of the new Astrantia differed primarily from plants of ‘Shaggy’ in the following characteristics:
    • 1. Plants of the new Astrantia were more freely-branching than plants of ‘Shaggy’.
    • 2. Plants of the new Astrantia had longer flowering stems than plants of ‘Shaggy’.
    • 3. Plants of the new Astrantia and ‘Shaggy’ differed slightly in involucral bract coloration.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Astrantia 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 actual colors of the new Astrantia plant.
The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Pisa’ grown in a container.
The photograph on the second sheet is a close-up view of typical leaves of ‘Pisa’.
The photograph on the third sheet is a close-up view of typical flowering stems of ‘Pisa’.
 DETAILED BOTANICAL DESCRIPTION
