I recall the berries being yellow or yellowish orange. I'll have to pay more attention this year.

I heard black nightshade (Solanum nigrum) leaves are edible and rantonettii leaves look very similar, thought they might be edible.

I believe that SOME forms of Solanum nigrum can be edible, if processed correctly, but I would not be willing to even attempt to find out if there is any truth in it.

I wouldn't even think about eating potatoe leaves, though the tubers are yummy.

Dont eat nightshade leaves or other plant parts unless you are 100% positive of ID and know for sure how to eat what parts are edible. It's like guessing with wild mushroom ID and eating.

This one is not for eating by mammals, including humans. It is tasty for hummingbirds and pollenators.

Solanum growing in the wild here in the upper south, US, have yellow/dark yellow berries.

OP’s plant is a different species from anything growing wild in the US. And, of the several wild species, berry colour varies from yellow through orange and red to black.

you need to find and join a LOCAL group of foragers.. and not rely on world wide STRANGERs to advise as to what is edible ... rumor and innuendo just dont work in this case ...

to my knowledge... EVERY PART OF A POTATO is poisonous.. except the spud.. how many peeps had to die.. before the last guy cooked the spud... it was probably a small family reunion ... dont be the first ones to try ...

google up your zipcode and foraging groups.. and make some new local friends..
