I grow the Wedding Party Wedding Bells - the double white one. I planted two a few years ago. You can see them in the back right of this picture, which was taken a week ago. They had started blooming with bright white blooms in January or February and until last week, were all pure white. As they age, the flowers turn green. They were both standing up nicely until a late snowfall in early April which flattened them.

Thank you so much for posting pic and sharing your experience of growing WPWB, Brooklynbonnie! It sounds like a wonderful hellebore and a robust one too. I have been looking for a pure white double hellebore and got this one on sale from Burpee. Do you have them grown in full sun or partial shade? How do they fare when exposed to sun?

They are planted in a spot with buildings to the south and west, and deciduous trees all around, so they get dappled to heavy shade in the summer and fall, except for 20-60 minutes of early morning sun when it first rises. In late fall to mid-spring, they get almost full sun as the leaves are gone from the trees. I think they LOVE this combo as they have really expanded in the 3 years I've had them. I wasn't expecting much even though the description said they could have 100 blooms on a single plant. I thought I'd be happy with 10 blooms, but by the 2nd year they were well past 10 blooms, and probably closer to 30. This year I didn't count but would not be surprised if they were nearing 50 blooms. :-)

Edit to add: I think from everything I've read, that they would be fine in full sun as long as they are well watered and in soil that does not get swampy. They are not really a shade plant, just shade-tolerant I've read.
