Here are a few I photographed at work, but there are TONS more, I will put some links to other photos below mine of some of my faves (and there are a LOT!)
Helleborus 'Winter Sunshine'
Helleborus 'Winter Song"
Helleborus 'Pink Lady'
Helleborus 'Green Corsican'
These beauties can tolerate deep shade but also appreciate some sun, they like well-drained soil (if you amend with organic matter or compost even better) and they are deer tolerant! Their leaves (when cut or bruised) emit a toxic sap that can irritate skin so wash well after pruning off any dead foliage in late winter when these gorgeous flowers begin opening their eyes to the chilly spring sky, it'll showcase the blooms that much more and make you happy you added them to your garden!

Would this be something you'd add to your garden? I know I'm always happy to see them blooming away when it's still chilly out!
