I've been growing a few varieties of Bergenia cordifolia for years and only recently ever had them bloom. The last few years, it seems like I notice a couple of fat flowerheads — and just as they start to uncurl — the bunnies bite them clean off. This year when I saw more flowerbuds pushing up than ever before, I determined to cage the plants so I could enjoy the blooms. I never did get around to that chore but it looks as though I may not be plagued with hungry rabbits this season as the plants are in full flower with nary a notice of any nipping.
The one with paler pink flowers is most likely Bergenia crassifolia and the darker one is either 'Bressingham Ruby' or 'Eden's Dark Margin.'
