"Poisonous" does not mean deadly. Some manifestations of toxicity are subtle. The dose, as always, determines if a plant is safe source of nutrients or a toxic hazard.

Lupinus spp.(Lupines)


Lupinus latifolius and several other species of lupine contain the alkaloid anagyrine. "Crooked calf disease" occurs if these lupines are eaten by a pregnant cow between 40 and 70 days of gestation. A tragic case from Northern California involved similar birth defects in a human child.
