Hellebore Winter Jewels 'Onyx Odyssey' (Helleborus) features very large, 3 in. wide (7 cm), fully double, cup-shaped blossoms, packed with 15-20 petals in shades ranging from slate to rich purple to black. The flowers keep most of their intense coloration and do not fade over time. Blooming heavily for weeks from late winter to early spring, these nodding beauties rise on sturdy, thick stems above the leathery, glossy, evergreen foliage, which emerge purple before turning into an attractive green shade. Showy and long-lasting, 'Onyx Odyssey' creates outstanding floral combinations with this other striking double Hellebore of the Winter Jewel series, Hellebore 'Golden Lotus'.
