Stinking Hellebore
At first glance, some hellebores are really nothing to look at, especially with face down to the soil as many
have evolved to grow. This can often be extreme enough that those in a border may be dismissed as a clump of foliage or missed altogether. However, with a bit of attention, their beauty mesmerises, and they shine.

While hellebores are well grown in gardens as a reliable perennial herb, Britain is the native home to only two species, which are woodland plants: stinking hellebore (Helleborus foetidus) and green hellebore (Helleborus viridis) known as green lily in Wiltshire.

Research published in 2010 discovered that yeast in the nectar of H. foetidus actually warms the flowers. As the yeast feed on the sugars within the nectar, their metabolic activity can raise the temperature of the flowers upwards of 2 °C above the ambient temperature. Bees show a preference for these heated flowers early in the season when temperatures are colder.
There is some traditional knowledge that I do not encourage you to attempt. In the past green hellebore has been used against worms in children. However, in 1762, two children died from such treatment at Fisherton Anger. It seems that they were treated with stinking hellebore, rather than green hellebore – perhaps showing that those in the past could be just as ignorant of the nature around them as some today. Further north, it is said that green hellebore was used to treat swollen udders in cows.
These days, I would suggest that hellebores are used purely for their aesthetic value as the plants are considered poisonous.
An interesting feature are the nectaries, which are the true petals on the plant and have evolved into tube-like structures to hold nectar for their pollinators, primarily bees and flies. These can be seen between the stamen and the sepals, which take over the petal's duty of being the 'showy' part of the plant. There are so many variations of colour and designs of hellebore flowers, from white to chocolate and green to shades of pink.
The sepals of hellebores can remain on the plant well after the sexual parts of the flower have finished their job. They turn themselves to photosynthesis, possibly contributing energy to the development of the seeds.

The bulging seed cases, show that it's been a good year for the hellebores.
The robust seeds of the hellebore are apparently difficult to get going and even after 8 weeks in a fridge can take up to 18 months to fully germinate.

  1. Hellebores aren't native here in the U.S. at all, but they certainly aren't invasive because of the reasons you mention. They are lovely plants and there are so many cultivars now, I can't imagine my garden without a few of them--at least. I keep wanting to add more. Great post!
