Lenten Rose (Helleborus orientalis Hybrids) – Zone 4 – If you want a particular colour, purchase them at your garden centre when in bloom. They make a spectacular display in the early spring garden. Plant in partial shade to full shade which helps preserve the vibrant colour of both the flowers and leathery, evergreen leaves. They do well under a variety of conditions and soil types, even under trees and shrubs and are long-lived.
