Hellelborus argutifolius is known for its large light yellow-green flowers in late winter/early spring but also for its evergreen foliage which is attractive year-round. Plants in colder regions should be well mulched and protected from winter winds. It prefers a well-drained or sandy soil but will tolerate clay if there is good drainage. It is drought tolerant when established. When grown in colder regions it should be protected from winter winds or foliage may be damaged. Helleborus comes from the Greek 'helleboros' meaning 'poisonous food' and the specific derived from the Latin words 'argutus', meaning "sharp" , and 'folius' meaning "leafed", describing the sharply toothed leaves. It may have occasional problems with crown rot and leaf spot. Quick ID Hints: Flowers nodding, petaloid sepals Short plant with stiff, large, evergreen leaves Leaves are palmately divided into many leaflets Flower center of numerous stamens outlined by tubular nectaries, or fleshy , beaked capsules Blooms in late winter to very early spring; utilized for borders or patios in protected, shady spots; poisonous leaves and roots- Greek 'helein'= to injure and 'bora'= food; excellent for long, winter blooming display. Numerous hybrid selections and species available, often difficult to distinguished, misidentified in trade, and each callen lenten rose, a name historically associated with H. orientalis. Prefers partial to full shade; prefers organic-enriched soil; intolerant of bright winter sun and high temperatures; Fungal diseases are main problem. This plant can spread through self-seeding. The NC Invasive Plant Council regards all hellebores as potentially invasive, although the threat is low. More information on Helleborus .
