Those are tatarian honeysuckle?

If so, its toxic as many plants are but wont kill you. Shits for sure. Prob vomit.

“Edible” is a spectrum

My point is only that there’s usually only a small number of plants you need to really memorize to NEVER eat and most of them are

Obvious Like Hemlock & foxglove etc

Just memorize the toxic nightshade berries and mushrooms you need to avoid and you’re pretty safe eating a little, waiting an hour before eating a bit more.

I could go on to add a ton of nuance but I made my point

This is only the advice Id give a fellow soldier in a survival situation… but its done me well over the years.
