ABSTRACT:
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Astrantia plant, botanically known as
Astrantia involucrata
, and hereinafter referred to by the cultivar name Snow Star.
The new Astrantia is a product of a planned breeding program conducted by the Inventor in Lisserbroek, The Netherlands. The new Astrantia originated from a self-pollination made by the Inventor of unidentified selections of
Astrantia involucrata
. The new Astrantia was selected by the Inventor in 1994 in a controlled environment from the resultant progeny on the basis of its large white inflorescences.
Asexual reproduction of the new cultivar by divisions harvested in Lisserbroek, The Netherlands, has shown that the unique features of this new Astrantia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Snow Star have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, irrigation amount and frequency, and fertilizer rate without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Snow Star’. These characteristics in combination distinguish ‘Snow Star’ as a new and distinct cultivar:
1. Upright plant habit.
2. Vigorous growth habit.
3. Freely and continuous flowering habit.
4. Large inflorescences with showy involucral bracts that are white with green apices.
Plants of the cultivar Snow Star can be compared to plants of the
Astrantia major
cultivar Alba. Plants of the cultivar Snow Star differ from plants of the cultivar Alba in the following characteristics:
1. Plants of the new Astrantia are taller than plants of the cultivar Alba.
2. Plants of the new Astrantia have larger inflorescences than plants of the cultivar Alba.
3. Plants of the new Astrantia flower for a longer period of time than plants of the cultivar Alba.
