One of the must-have staples of any garden is the Hellebore or Christmas Rose.  With over 25 varieties available, this evergreen clump-former fills a mid to front of border gap with colour.

Plant next to golds, whites and reds to show off the beautiful cup-shaped flowers to their greatest extent.  These are long flowering perennials and can tolerate some shade so are incredibly useful for planting under deciduous trees for interest through the winter months.
