Stinking hellebore Helleborus foetidus Green - Hardy plantStinking hellebore? Yes, that's another name for the Helleborus foetidus. It's named after the smell released by the flowers if they're crushed. The greenish flowers bloom in winter, from December until spring. Great for some extra colour in the garden or in a flowerpot on the garden table. Put the plant in loose, fertile soil, perhaps with some lime. A shaded or semi shaded spot is fine. The Helleborus foetidus will grow to approximately 50 cm tall
