In addition to looking stunning in the new year, hellebores have interesting ways of attracting the few pollinators that are out of hibernation so early-on.
Research has shown that the nectar of hellebores contains natural yeast which, as it degrades, releases heat and a pungent aroma (exactly like the composting process). Due to the drooping cup-like structure of the plant's sepals, this creates a microenvironment of humidity and strong odours. Both of these features are alluring to any pollinators during the winter months, giving hellebores the edge over less equipped early-flowerers. The best example of this kind of Hellebore is H. foetidus (of which photos will appear on this blog next month).
Additionally hellebores are toxic, and will cause diarrhoea and other discomforts should they be ingested.
