This is toothwort, sometimes called pepperwort.It is a peppery tasting edible.
One of my favorites, the lacy & delicate Dutchman's Breeches.
Spring Beauty, which has strap-like leaves & white, pink veined flowers.Also called Fairy Spuds, since the corms (roots) are edible.
This is Hepatica or Liverwort, which can be confused with Spring Beauty.It can have white, pink, lavender, purple or blue flowers.
Hepatica again, showing its 3 lobed pointed leaves.
