Family

Ranunculaceae

Botanical Name

HELLEBORUS x hybridus 'Pine Knot Select'

Plant Common Name

Hybrid Lenten Rose

General Description

A colorful strain of hellebores developed by Pine Knot Farms of Clarksville, Virginia, these seed-grown hybrids of Lenten rose (Helleborus orientalis) make outstanding additions to the shade garden. From winter into spring they bear buttercup-shaped or semi-double flowers on sturdy stems above substantial clumps of shiny, leathery, jaggedly hand-shaped evergreen leaves. The fresh lime-green new leaves appear with the blooms. Flower colors include white, pink, apricot, burgundy, pale green, and pale yellow, sometimes with contrasting speckles, halos, or centers.

Hellebores prefer a rich, loamy, neutral to alkaline soil, and some protection from sun and drying winds. They often self-sow to form large colonies. Combine them with shade-loving bulbs, evergreen ferns, perennials and shrubs. Unlike many plants that bloom at this time of year, deer don't bother them.
