I'm very interested in the various forms of bloodroot, Sanguinaria canadensis. I don't have much in the way of bloodroot in my garden, but I hope to remedy this situation. A couple years ago I went in "halfsies" (slang for splitting the cost) with a friend for a great pot full of Sanguinaria canadensis 'Multiplex'.
The distribution of this plant is quite succinctly eastern half of North America:

They're coming up now, and I'm fascinated by the early leaf-bud form, looking like little people wrapped in shalls, the enveloping leaves membranous and with raised veins, I also get the impression of bat wings wrapped tight around their resting bodies. I hadn't noticed before, but the buds are initially tinged with pink. I am showing 4 views, taken in two different light conditions.
If others have photos of the other flower forms, please post them here, things like the "Tennessee Form".
