The silky lupine occurs in fescue prairie in southwestern Alberta, and in the fescue grasslands and yellow pine zones in the interior of British Columbia. The seed and pods of lupines are the most poisonous parts, but the leaves may cause trouble if large quantities are eaten at one time. Half a pound of seeds can cause death.
Years ago we saw a llama in Oregon who was born blind. Her mother had eaten lupine while she was pregnant.
