- Comments
- Powdery milkvetch is fairly common in the foothills and lower montane on the west side of the Valley. The Lower Basin records of Astragalus cerussatus come from around the San Luis Hills. It is a "rare" native plant that likes the center of hiking trails in foothill rocky terrain. In one instance, a plant has reseeded itself for 8 years in an urban gravel driveway of Del Norte (Rio Grande Co, 2015-2023). The mottled seeds of this plant sometimes have a light-colored tip that looks like an elaiosome, although there are no observations of elaiosomes in Astragalus. A. cerussatus would be endemic to Colorado except for a few collections from Taos and Rio Arriba counties in New Mexico.
