Yeah, I forgot about these from back home! I used to eat Beech nuts when I was a little kid on trail walks with my dad. I have collected mulberries too - they are great. I never tried "Pokeweed", but I know people who love it. It sounds like too much work for me (like with acorns).
Pokeweed is vastly less effort than acorns, speaking as someone who has processed pounds of acorns.
Black cherries (more often than not, I don't like the fruit, but once in a while it is good and sweet)
Mulberries are great.
Wild blueberries (low and high bush)
Wild raspberries
Wild blackberries
Thimbleberries (Very strong flavor from where I've had them, quite tasty)
Beach plums (I picked 40lbs last year. They are so good. I have tons of jelly and fruit leather.)
elderberries
autumn olive (I have never once found them when they were not sour and astringent, sadly)
Purslane (makes an excellent potato salad)
Plantain
Jewelweed shoots
Sheep Sorrel
Field Garlic (ever-present)
RAMPS! (I have a heap in the fridge right now)
Young dandelion leaves/flowers
Chickweed (I eat it from the pots at the garden center where I work. It gets big and healthy with regular watering)
burdock (I found it very strong flavored last time I used it. I think I'll try blanching it first next time)
Queen anne's lace (if I can catch it early enough this year...)
Pokeweed shoots (too early)
knotweed shoots (I am not a fan but they are plentiful right now)
Ginko nuts (absolutely fantastic, but they're not "wild" and they reek right up until you roast them before eating)
Spicebush. Chew the twigs for a long lasting spicy/peppery flavor, mix leaves and twigs for tea (leaves smell great but have no flavor), berries are a good seasoning.
Black birch- I chew the twigs for the wintergreen flavor, though I prefer actual wintergreen, which isn't in the immediate area.
Black walnut (dyes your hands brown real good too)
cattail
fiddleheads
daylily shoots (mild, with a hint of spicy, very good. they get unpleasantly strong, quick though) and flowers (mild, simple, good snack in the garden)
wild grapes (last year was so dry that I found them unpleasant)
pine needles (tea)
Acorns (a ton of effort but they make a great, moist, dense, sweet brown bread if leached properly)
greenbrier shoots (very tasty, epecially when young. I cut big vines at waist height to try and force big fat shoots from them)
violets (leaves and flowers. plain. not much flavor)
hercules's club (devil's walking stick) shoots. I finally found a stand, need to go harvest in a week or so.
Mushrooms- Chicken mushroom, morel, giant puffball, and maitake (hen of the woods). I'm not very brave with mushrooms, so I stick to the easy ones.
