Helleborus orientalis is the botanical name of the very popular, early blooming shade perennial more commonly known as the Lenten Rose. Lenten Roses are very hardy and grow in zones 4-9. They get their name because they normally begin to bloom during the Easter celebration of Lent. When they are not in bloom they remain as lush deer resistant ground cover throughout the year. They prefer shade to partial shade and are excellent for naturalizing and grow in most soil types.
