Editor's Note

The seeds of all Lupinus species and cultivars are poisonous if ingested. They contain alkaloids such as lupinine, anagyrine, sparteine, and hydroxylupanine. Symptoms of poisoning include respiratory depression and slow heartbeat, sleepiness, convulsions.

We tend to err on the side of caution in PlantFiles, and the poisonous details listed above are a precaution to gardeners, parents and pet owners.
