Notes
USDA Plants National Database recognizes four varieties of A. bisulcatus, all native to the U.S. Two varieties are native to Colorado. Variety bisulcatus is found on the east slope, including the Fort Collins area and variety haydenianus is primarily found on the west slope. Variety major is documented in the southwestern U.S. and variety nevadensis in Nevada.
This is an important larval and adult food host for many of our native invertebrates. It primarily grows in selenium-rich soils and accumulates selenium in its tissues.
