Colton's Milkvetch

Astragalus coltonii, Colton's milkvetch, is a perennial legume in the family Fabaceae assessed as Least Concern by the IUCN. The genus Astragalus is the largest genus of flowering plants globally, with over 3,000 species distributed primarily in temperate and arid regions of the Northern Hemisphere. Astragalus coltonii inhabits diverse terrestrial environments, typically including semi-arid shrublands, rocky soils, and open desert margins where competition from taller vegetation is limited. Like other milkvetches, this species likely forms root associations with nitrogen-fixing bacteria, enabling it to colonise nutrient-poor substrates and contribute to soil fertility improvement in its habitat. The pinnately compound leaves, pea-type flowers, and inflated seed pods characteristic of the genus are typical features of this species. Milkvetches provide forage for native pollinators and serve as larval host plants for several butterfly and moth species. Some Astragalus species accumulate selenium or alkaloids from the soil, making them toxic to livestock, though the toxicological properties of A. coltonii specifically have not been well characterised. Biological traits of this species remain poorly documented in the scientific literature.
