Nightshade for blueberry
Shiny black berries in a hedge are not Vaccinium. Atropa is a tropane. A handful has ended walks.
Blueberry is a low ericaceous shrub; the berry has a five-point crown and many small seeds. Deadly nightshade is a sprawling solanum relative with a persistent calyx and a single berry like a black cherry. If it is not a heath, it is not a blueberry.
The Herbarium — a teaching catalog, not a clinic. Traditional use is history, not a prescription. USDA 6b dates are a week either way, not a promise. Do not eat, drink, or harvest a plant you cannot name.
