Hellebore

From what I read, at www.hellebores.org, this is likely to be Helleborus x hybridus. In other words, I'm not quite sure!

Hellebores are referred to as far back as ancient Greek and Roman literature, and they have a long history of cultivation in Europe for their medicinal purposes.

They are unusual looking plants, and not to everyone's taste, but, if you will excuse the (dreadful) pun, they are growing on me.

This plant faces east, so I took this shot early in the morning, not long after sunrise after a very frosty night when the thremometer in the greenhouse had dipped just below zero.
