I am also starting my open carpets of hellebores in a new woodland style border.
I have recently purchased 30 plugs from Hayloft Plants (mail order) which worked out at about a pound per plant. 10 varieties - 5 single & 5 double (I think). They are all sturdy little plantlets - potted up in December and already sending roots out of the pot and new leaf growth.
I have a couple of mature flowering plants and will collect seed from them this year but you can also buy packets of seeds.
I shall also buy a couple of choice specimens from Harveys Garden Plants (Suffolk - but they do mail order). Fortunately they are just up the road from me and they do a couple of wonderful hellebore / snowdrop days late Feb / early Mar - worth visiting if you fancy a trip out. Roger Harvey is a regular at Chelsea & has gold medals for his hellebores. Not cheap - but worth it if you want a couple of special plants.
Nothing to add to Verdun's advice re cultivation - he knows his stuff!
