crazyweed

Crazyweed is another name for locoweed, a poisonous plant found in North America. These plants, belonging to the genera Astragalus and Oxytropis in the pea family, can cause frenzied behavior, impaired vision, and even death in livestock and horses if ingested. While generally unpalatable, they are sometimes eaten when other forage is scarce. Toxicity can vary based on soil conditions, with decaying plants releasing toxins that may be absorbed by other crops. Crazyweeds are typically low-growing with compound leaves and spikes of pealike flowers.12
