A Redditor, known as "Nightshade", has encouraged foragers to eat this plant, which is rapidly spreading in the US. The user shared a photo of Solanum nigrum berries, which are often associated with toxicity warnings but can be found to be edible. Black nightshade is considered an introduced species in North America and can spread aggressively, competing with native plants and disrupting local ecosystems. However, some foragers believe that harvesting these plants could be a small but meaningful way to reduce their spread while receiving free, local food. The post also highlighted the challenge of plant identification and food safety.
