Abstract

A new and distinct cultivar of Astrantia plant named `Roma`, characterized by its upright growth habit; numerous reddish purple flowers with white to light pink horizontal involucral bracts; early flowering; continuous flowering without shearing; and excellent cut flower and garden performance.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Astrantia plant, botanically known as Astrantia major, and hereinafter refered to by the cultivar name `Roma`.
The new Astrantia is a product of a planned breeding program conducted by the Inventor in Hummelo, The Netherlands. The objective of the breeding program was to create new Astrantia cultivars with unique flower colors, early flowering, and continuous flowering.
The new Astrantia originated from a cross made by the Inventor of the Astrantia major cultivar `Ruby Wedding` (not patented) as the male, or pollen, parent with an unnamed selection of Astrantia major var. involucrata Koch as the female, or seed, parent.
The cultivar `Roma` was discovered and selected by the Inventor in 1992 as a flowering plant within the progeny of the stated cross in a controlled environment in Hummelo, The Netherlands.
Asexual reproduction of the new cultivar by divisions harvested in Hummelo, The Netherlands, has shown that the unique features of this new Astrantia are stable and reproduced true to type in successive generations.
BRIEF SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Roma`. These characteristics in combination distinguish the new Astrantia as a new and distinct cultivar:
1. Upright growth habit.
2. Numerous reddish purple flowers with white to light pink horizontal involucral bracts.
3. Early flowering.
4. Continuous flowering without shearing.
5. Excellent cut flower and garden performance.
Compared to plants of the male parent, the cultivar `Ruby Wedding`, plants of the new Astrantia differ in the following characteristics:
1. Plants of the new Astrantia have reddish purple flowers whereas plants of the cultivar `Ruby Wedding` have red flowers.
2. Plants of the new Astrantia do not produce seed whereas plants of the cultivar `Ruby Wedding` produce seed.
3. Plants of the new Astrantia flower about one month earlier in the spring than plants of the cultivar `Ruby Wedding`.
4. Plants of the new Astrantia are more floriferous than plants of the cultivar `Ruby Wedding`.
5. Involucral bracts of plants of the new Astrantia are more horizontal than involucral bracts of plants of the cultivar `Ruby Wedding`.
Compared to plants of the female parent, an unnamed selection of Astrantia major var. involucrata Koch, plants of the new Astrantia differ in the following characteristics:
1. Plants of the new Astrantia have reddish purple flowers whereas plants of the unnamed selection of Astrantia major var. involucrata Koch have greenish white flowers.
2. Plants of the new Astrantia do not produce seed whereas plants of the unnamed selection of Astrantia major var. involucrata Koch produce seed.
3. Plants of the new Astrantia have smaller inflorescences with shorter involucral bracts than plants of the unnamed selection of Astrantia major var. involucrata Koch.
4. Plants of the new Astrantia are more floriferous than plants of the unnamed selection of Astrantia major var. involucrata Koch.
The new Astrantia can be compared to the Astrantia major cultivar `Shaggy` (not patented), however, in side-by-side comparisons conducted in Hummelo, The Netherlands, plants of the new Astrantia differ from plants of the cultivar `Shaggy` in the following characteristics:
1. Plants of the new Astrantia have reddish purple flowers whereas plants of the cultivar `Shaggy` have greenish white flowers.
2. Plants of the new Astrantia do not produce seed whereas plants of the cultivar `Shaggy` produce seed.
3. Plants of the new Astrantia have smaller inflorescences with shorter involucral bracts than plants of the cultivar `Shaggy`.
4. Plants of the new Astrantia are more floriferous than plants of the cultivar `Shaggy`.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Astrantia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a side perspective view of typical flowering plants of the new astrantia grown in the landscape. Foliage and flower colors in the photographs may appear different from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
