Leontopodium nivale subsp. alpinum Blossom of Snow (‘Berghman’), was bred by Herman Berghman, a Belgian florist, who was frustrated to find that he was unable to source edelweiss plants with a long-stemmed habit that produced tall enough flowers to be useful as cut flowers, in floral arrangements. Herman Berghman spent the next ten years breeding a new edelweiss cultivar that met his requirements, and successfully produced long stemmed edelweiss flowers, with a good vase life. Leontopdium nivale subsp. alpinum Blossom of Snow (‘Berghman’) is a plant that is the result of Herman Berghman’s breeding work.
