Blackberries are delicious and popular berries known for their rich dark purple or black color when ripe. However, it’s essential to be able to distinguish them from their toxic lookalikes. Dewberries, which are smaller and less plump than blackberries, are often mistaken for them but are safe to eat. On the other hand, nightshade berries, such as deadly nightshade and bittersweet nightshade, as well as pokeweed berries, can resemble blackberries but are highly toxic if ingested. Accurately identifying blackberries and their lookalikes is crucial when foraging for berries to avoid confusion. Consulting reliable field guides or local experts is recommended when uncertain about a berry’s identity. If you accidentally consume an unfamiliar berry, it’s important to take immediate action, including rinsing your mouth, seeking medical attention, and monitoring any symptoms that may develop. When in doubt, it’s better to err on the side of caution and seek medical attention.
