“The Christmas Roses with which one meets in the majority of gardens are not white, but pink, or more or less suffused with pink or dirty purple.”
Really? Well, perhaps it was true in 1878 when a certain Mr. D. T. Fish wrote those words in William Robinson’s epic journal, The Garden, although it seems unlikely. He then goes on to explain in detail how to make Christmas roses (Helleborus niger) white.
Even allowing for the artist’s overenthusiasm, this Giant Christmas Rose, illustrated in The Garden in 1878 (above), is impressive and well illustrates how the coloring works: individual flowers open white and develop pink tones and become richer in color as they mature. Sunset Group, collected in Slovenia by veteran British hellebore expert Will McLewin was similar (but a whole lot less dramatic). Dark stemmed ‘Louise Cobbett’ opens with pink backs to its flowers and later develops additional pink tints but it’s not the color of the Giant Christmas Rose.
Neither is Blackthorn Group (below), developed by acclaimed hellebore and daphne breeder Robin White from ‘Louise Cobbett’ (right) and ‘White Magic’ although it’s a lovely thing.
Strangely, Josef Heuger, in Germany, who has introduced so many fine forms of the Christmas rose recently - ‘Jacob’ flowers dependably in November here in Pennsylvania - has created no pinks. Most of the pink ones such as ‘Pink Frost’ which listed as H. niger by mail order nurseries are actually hybrids. If Ernie and Marietta O’Byrne of Northwest Garden Nursery in Oregon, who’ve created so many spectacular double and single forms of H. x hybridus, turned their attention to Christmas roses we’d be in for a treat.
Anyway, it’s interesting (if difficult to believe) that pink was once normal in Christmas roses and that detailed suggestions were given in The Garden for turning them white. And what, in short, were the recommendations: “light soil”, “a warm, sheltered, partly-shaded situation” and “cover them with glass”. Somehow that doesn’t really seem a very convincing way to change their color…
