Wildflowers on dog walks

While the dogs are searching for the great smells of Spring, I'm lucky to find wildflowers.
The first one I spotted, I call Hepatica, but now I'm looking for the difference between Hepatica
and Bloodwort (red juice in stem). Will get some photos when they show their faces again on a sunny day.... today is rainy , and we need it. I see signs of Dutchman's Breeches, leaves are poking up from the leaf cover. Also looking for signs of Jack in the Pulpit on my back trail.
We do have the odd little Indian Pipe, devoid of chlorophyll, but that will come later, usually in rotting leaves under some pines.
