I live on the Outer Banks in North Carolina.
Right now in my small neighborhood I forage wild mint, groundcherries, lamb's-quarters, & dandelions/cat's-ear. Yucca flowers are a nice little treat or an addition to salads!
I haven't been able to find blackberries or huckleberries for weeks now.. I think they've all been eaten by rabbits racoons & birds because it's been so dry here lately.
Wild carrots are abundant in a few areas as well
Also, at the beach there are an unbelieveable amount of prickly pear cactus [fruit, seeds, pads & flowers are all edible] & "searockets" are a great plant I've learned about this year, they kind of taste like horseradish.
Hmm.. and since this says wild foods & not just plants I want to add that for the first time in my life this year I've eaten "molecrabs" or "sandfiddlers" the little crabs that dig super fast into the shore! I've only tried them twice this year fried both times but they have an awesome flavor something like shrimp or bluecrabs & there are so many of them I don't feel bad about eating them! But it is quite a task to collect them.. I'm sure one could master it though.
Oh yeah! There are SO many figs on this island that there are many trees popping out of the woods & in abandoned lots they are practically wild now!
oh yes, I forgot about mushrooms. We have puffballs coming up now. They are edible and save them when they get all dried out too. The spores in the mushroom are good for big cuts till you can get to the ER
