Where winters are too cool or damp for much else to bloom, hellebore are more popular. The most popular are Helleborus X hybridus, which are hybrids of a few similar species. Most are direct descendants of Helleborus orientalis. They are more resilient to frost than to arid warmth during summer. Actually, that is very likely why they are less popular here.
Locally, hellebore are useful for cool, damp or partly shady situations. However, they are not as substantial as ferns. Also, they can get a bit wimpy as the weather warms through summer. Although evergreen, they shed some of their older yellowing foliage. They grow most during late autumn, winter and perhaps early spring. They crave richly organic soil.
Floral color is typically subdued but interesting. Most common hellebore flowers are pale pink or almost grayish white with spots. Alternatively, they can be rusty red, maroon, pale green, yellow, gray or almost black. Some exhibit more or less spots, blotches, stripes or picotee edges. Double flowers are rufflier than single flowers are. All hellebore are toxic, and for some, can cause dermatitis.
