Helleborus (Rodney Davey Marbled Group) Dana’s Dulcet (‘Epb 30’) (PBR)

The outward-facing flowers of this hellebore are larger than average, and as they perch on tall, upright stems that rise above the silver-mottled foliage, they put on a much showier display. Each bloom has a starburst-like boss of stamens, which is surrounded by quite leathery (and therefore long-lasting) reddish purple and green petals, that add a much-needed shot of colour to the winter garden.
