We all know one or two ancient eggplant relatives.
LOL!
There’s a tiny yellow variety I love, but they aren’t quite tomatoes, they’re more closely related to solanum nigrum (black nightshade). There’s a red variety of this that’s also edible. I mean, you *can* eat deadly nightshade, but it could turn into a major backfire.
Very important family of food plants though — tomatoes, peppers, potatoes, eggplants; more distantly the tomatillo and nantucket ground cherry; non-food crops like tobacco; various decorative stuff like petunias and nicotiana, and some that are at least somewhat poisonous, such as chinese lanterns, jerusalem cherry, poinsettia, oleander, datura... probably forgetting some. :^)
