Those native, low-growing trailing blackberries (Rubus ursinus)have such a wonderful flavor! All that flavor must be concentrated, since it's in such a small berry, lol. How great that you take your son berry picking, too! Some kids really take to foraging. They can pick a lot of berries! ; )

I'll have to make a post about skunk cabbage. They definitely take more effort than berries or many greens. But they have a unique place in foraging. Prepare them wrong, though, and it feels like your throat is getting shredded with little pieces of fiberglass!
