Culture
Easily grown in organically rich, fertile, humusy, alkaline, medium moisture, well-drained soils in part shade to full shade. Prefers light to moderate shade. Although the foliage is evergreen, it may become scorched and tattered in extremely harsh winters, particularly if not sited in locations protected from cold winter winds and/or insulated by snow cover. Cut back flowering stems after bloom to promote new foliage growth. Established plants that become congested may be divided in late summer to early fall. Hybrid hellebores are often grown from seed (some come true and some don’t), but plants will take two years to bloom when grown from seed.
Noteworthy Characteristics
Hybrid hellebores, sometimes commonly called hybrid Lenten roses or hybrid winter roses, are bushy, clump-forming perennials which typically grow to 12-15” tall. They are noted for producing single, cup-shaped flowers (typically 2-3” diameter) with five showy, usually overlapping petals (technically sepals), but sometimes come in a double flowered form. Flowers bloom in a large variety of colors, including various shades and tints of white, pink, red, purple, and yellow, and sometimes have inside spotting. Bloom typically commences in late winter extending into early spring. Flowers appear at the tips of branched stems clad with evergreen dark green leaves which are divided into glossy, leathery, deeply-lobed, often toothed, lanceolate to elliptic segments.
Genus name comes from the Greek words bora meaning "food" and helein meaning "injures/destroys" in reference to the plant’s toxic leaves, stems and roots which are poisonous to humans if ingested.
Hellebores is the old Greek name for H. orientalis.
'Brushstrokes Strain' is a bushy, clump-forming evergreen strain of single-flowered hellebores introduced by hellebore breeder Marietta O'Byrne. These are acaulescent (without stems) hybrids that typically grow to 8-12” tall and to 12-24" wide, and are noted for their glossy, leathery, evergreen, dark green leaves (7-9 segments) and late winter to early spring bloom (March to May) of single flowers (2-3" diameter) which appear in a variety of rich colors including purple, pink, red, yellow and green, often further adorned with ornamental blotches, spots and splashes (essentially a mixture of some of the best single-flowering hellebores previously hybridized by the breeder). Each flower has five large, showy, petal-like sepals (petals are quite small and inconspicuous). Flowers are long-lasting in the garden in large part because sepals last longer than petals.
Problems
No serious insect or disease problems. Crown rot and leaf spot are occasional problems. Leaves, stems and roots are poisonous. Deer and rabbits tend to avoid this plant.
Uses
Flowers that bloom in February/March in St. Louis are true harbingers of spring. Best planted in large groups. Locate plants near a kitchen window, patio or walkway so that the early bloom may be enjoyed to the fullest. Group in shady locations under trees, large shrubs or in woodland gardens. May also be incorporated into a naturalized area where the clumps will slowly spread through self-seeding. Mass for an attractive year round ground cover.
