Disturbed habitats should produce pokeweed, a fabulously tasty, highly nutritious potherb that's poisonous if you consume it raw, or dine on the roots, berries, or seeds.
Wet areas could harbor cattails, with shoots tasting like asparagus in season now; various wild mint species; or even wild watercress.
We'll look for sassafras, the original source of root beer, in the woods, along with wintergreen-flavored black birch trees; and spicebush leaves, for making a flavorful anti-fever tea.
Given enough rain beforehand, we could run into some choice spring mushrooms. There may be chicken mushrooms, dryad's saddle, wine-cap stropharias, or even morels.
