This application is related to a European plant breeders' rights application filed on Jun. 29, 2015, application No. 2015/1085. There have been no offers for sale anywhere in the world more than one prior to the filing of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed plant breeder's rights documents.


The present invention relates to a new and distinct cultivar of Leontopodium alpinum and will be referred to hereafter by its cultivar name, ‘Berghman’. ‘Berghman’ represents a new mountain flower for landscape use and for use as a cut flower in particular.

The new cultivar of Leontopodium alpinum was discovered in the Inventor's garden in spring of 2008 in Asse, Belgium as a chance seedling from 1,500 seeds he planted of unnamed and unpatented plants of Leontopodium alpinum. The Inventor selected ‘Berghman’ as a single unique plant amongst the seedlings in 2010.

Asexual propagation of the new cultivar was first accomplished by division by the Inventor in 2011 in Asse, Belgium. Asexual propagation by division, stem cuttings, and tissue culture intitiated from meristem tissue has determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.


The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Berghman’ as a unique cultivar of Leontopodium.

    • 1. ‘Berghman’ exhibits very long flower stems for good suitability as a cut flower.
    • 2. ‘Berghman’ exhibits large flowers.
    • 3. ‘Berghman’ exhibits a fast rate of propagation.

The new Leontopodium can be most closely compared to the cultivars ‘Matterhorn’ (not patented) and ‘Mt. Everest’ (not patented). Both are similar to ‘Berghman’ in having flowers that are greenish white in color. Both ‘Matterhorn’ and ‘Mt. Everest’ differ from ‘Berghman’ in having smaller flowers, flowering stems that are half the length, and in being slower to propagate.


The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Leontopodium. The photographs were taken of plants about 3 years in age as field grown in Boskoop, The Netherlands and placed in a container for the photographs.

The photograph in FIG. 1 illustrates the plant habit of ‘Berghman’ in bloom.

The photograph in FIG. 2 provides a close-up view of the flowers of ‘Berghman’.

FIG. 3 provides a close-up view of a leaf of ‘Berghman’.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Leontopodium.


The following is a detailed description of three year-old plants of the new cultivar as filed grown in Booskoop, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
