Of the 3 pictures, the first two look like Prenanthes and the third one looks like Toothwort. There are several different species of toothwort and the basal leaves are right for one of them (can't remember the species name). Does it have 4 white petals?

It's odd that I've never been to Whitewater, being so close to it, but I was out at Carley about 3 years ago when the bluebells were in bloom and they were unbelievable! Seems like that was just a little bit later in the season, but maybe not..

OMG Marie - I don't want to be a downer, but did you read the negative feedback at Garden Watchdog? The most protracted rant came from a lady who did exactly what you are proposing and sounded like she wanted to go back in time and dope slap that very idea out of her own head by the end of her ordeal. That being said, I HAVE done a group order of Helebores on a smaller scale from SG and it was OK. There were only three of us - Dee, another swapper friend and I. The plants were nice enough, but small as should be expected. Nothing that has inspired me to order from him again, but I wouldn't totally rule it out. I get their emails and laugh at their pricing because whether it is something exotic-ish or as common as Garlic chives he seems to charge the same two pricing structures for everything and presents it with the same huckster patter. Of course he also has some good growing information to impart also. He must really be a character in person.

Perhaps a Cardamine sp. such as diphylla. Formerly known as Dentaria.
