Respiratory depression and bradycardia (slowed heartbeat) are among the symptoms. Excavations around the Arctic Tundra region have led to the finding of seeds of Lupinus arcticus, which remained viable for 10,000 years before germinating and flowering.

These seeds were recovered from an ancient rodent results of viability tests should be made available before seeds are packaged and placed in the genebank so that poor-quality seeds can be identified and regenerated. Viability of seeds can be known by two methods: (i) Ability to germinate, (ii) Testing their ability to respire. Lupinus arcticus has compound, broad leaves and blue flowers. The thousands of years old viable seed of Lupinus arcticus excavated from. Perennial varieties of lupine grow in U.S. Department of Agriculture plant hardiness zones 4 through 8.
