Set plants 12 to 18 inches apart, in a rather fertile soil that is well-drained but moisture- retentive. Helleborus does best in partial shade, but can tolerate full sun in northern areas. For the taller species and cultivars, choose a somewhat sheltered location.
We recommend a year-round mulch, to conserve moisture and keep the soil cool. If plants must be divided, do so carefully, as they tend to be brittle. H. orientalis hybrids transplant readily; others are happier left undisturbed. If slugs appear, use appropriate bait.
