14. Oregon – Foxglove (Digitalis purpurea)
Foxglove is widespread in Oregon and admired for its tall spikes of purple, pink, or white bell-shaped flowers. Beneath its ornamental charm lies a powerful toxin: cardiac glycosides that interfere with heart rhythm. Ingesting foxglove can cause nausea, confusion, irregular heartbeat, and fatal cardiac arrest. Although compounds from the plant are used medicinally in controlled doses, consuming any part of the raw plant is extremely dangerous. Foxglove often grows along trails and forest edges, increasing the risk of accidental exposure for hikers and pets.
