Interesting, nigrum probably had more selection breeding.
Do you think we can increase the size of Black Nightshade? Maybe it can become Cherry Tomato Size instead of currant tomato size? I wonder if you cross multiple diverse species that a Chromosome Multiplication event can happen & increase the size similar to how it happen to the domesticated BIG Strawberry?
Oh yes, Forager Samuel Thayer in his book talks about the conflicting info! To summarize, most problems arose from Confusing Deadly Nightshade (Atropa belladonna) With The Perfectly edible Black Nightshade (Solanum nigrum Complex). and some may have eaten unripe green berries, there’s no concern with fully ripe Black berries (or White in Solanum villosum).
Now that’s the attitude we Need! I hope you can Breed better Black Nightshade too! It’s a crop I’m fascinated in. Oh btw After Frost, do you clear out the Black Nightshade plants? According to Forager Blanche Cybele Derby on Youtube, berries can survive several frosts, which gives some berries enough time to ripen fully despite frosts. I’ve also seen these ripen the same way Slightly unripe Green Tomatoes do, I harvested some green berries & placed them next to ripe Black Nightshade berries. They Ripened fully after a few weeks and were perfectly edible just like ripened off the vine green tomatoes.
Here’s her video on Black Nightshade, I’ve learned a lot.
