For whatever reason I’ve always loved what my Grandmother called “Blackcaps” or wild black raspberries even more that the cultivated reds. They generally grow wild along roads and the edge of woods. My property has a fair number of them, not enough to make jam or anything like that, but they are a nice treat to pick and eat while doing tasks. They are just now coming on in my area and I look forward to snacking on them for the next couple of weeks.
It pays to be observant and learn what edibles grow wild in your area and more important close to where you are if not on your own property. In this case knowing they are black raspberries means not trying to eating them when they first turn red. If I had more time I would be hitting the ditches in my area to get more and make jam, but not this year.
