Bloom Time: Late fall to spring
Helleborus lividus subsp. corsicus is a quick-growing, clumping evergreen perennial with leafy stems that grow up to 4 feet (1.2 m) tall. It bears large leaves with three individual leaflets marbled, blue-green above, somewhat purplish beneath, and noticeably toothed along the margins. Large light yellow-green flowers appear above the leaves in clusters from late fall to spring.
USDA hardiness zone 6a to 9b: from −10 °F (−23.3 °C) to 30 °F (−1.1 °C).
How to Grow and Care
Place the Hellebore into well-draining, organic soil in filtered sun or shady location when planting from seed or division. The Hellebore plant will return for many years; make sure space will accommodate growth and has proper sunlight.
Hellebores need no more than a few hours of dappled light and grow successfully in shady areas. Plant the Hellebore under deciduous trees or scattered through a woodland garden or shaded natural area.
Soaking the soil in which the Hellebore is growing helps the Hellebore plant to look its best. Hellebore care includes the removal of older leaves when they appear damaged. Care for Hellebores should also include careful fertilization. Too much nitrogen may result in lush foliage and a shortage of blooms.
Plant Hellebore seeds in the fall. A 60-day moist chilling period is needed when planting seeds of the Hellebore plant. Planting seed in fall allows this to happen naturally in areas with cold winters. Wait three to four years for blooms on young plants grown from seed. Divide overgrown clumps in spring, after flowering, or in autumn.
