It's Hellish for Hellebores

I felt so sorry for them, curled up against the cold wind on the windowsill.
I will have to ask them to leave the bathroom sink later but for now they can stay there.
The bathroom is freezing but not as cold as it is outside. It's almost as windy in here too (the draughts are so strong that one of the internal doors keeps blowing open and I had to sit wrapped in a blanket this morning).
Did you know that snowdrops have a similar chemical in them to anti-freeze?
