It's always exciting to find wild edibles, and even more so when you're able to identify them and safely consume them. I'm glad you had the opportunity to learn about some new plants and even get a little snack in the process.
I've also been interested in learning more about wild edibles, but I've been a little hesitant to try them because I don't want to get sick. I'll have to check out the app you mentioned. It sounds like a great resource for identifying wild plants.
The app I use is a plant identification one, Plant Snap I believe the name is. You get 5 free picture identifications a day and I certainly used them up that day! Lol. Enjoying wild edibles is great indeed! I was very confident in the blackberries which is why I ate them. Blackberries and blueberries are ones I have a lot of confidence in identifying and eating, the other ones not so much though lol
