During these last few weeks of grey cold and wet weather I have been craving some colour for our garden. So we bought 2 pots of hellebore which are flowering. I plan to plant them out in the back garden in a few days. They are supposed to be frost resistant but I thought I'd wait just in case we get another cold snap. I looked them up and they were once used in witchcraft and the black variety are supposed to be poisonous. There is a suggestion that Alexander the Great's death at 32 was caused by him taking an overdose of medication containing hellebore.
