The night shade will seed and unless you have a big garden one is plenty. It's poisonous, the berries at least, possibly other parts.
Phytolacca is another large plant that seeds about the garden. Enormous roots but not invasive by roots, just by seed. More poisonous berries.
I may be wrong on the phytolacca, mine are nowhere near flowering but there are other species that might be earlier. Mine is P.americana according to its label. I have seen others that aren't quite like mine with the same label.
