Narrative
Silverleaf scurfpea is a short, 1-1.5' tall forb that is common throughout most of the middle and upper Midwest stretching from Oklahoma north to Canada. This species can form large clonal colonies via rhizomes at approximately 6-8" below soil level. Genetics of this accession originate from central Iowa which is close to the eastern edge of the species native range. Seed production is extremely rare and the presence of this species in native seed production nurseries or nursery trade is non-existent (2024). Small dark-blue flowers generally appear (central Iowa) in early June. Flower stalks, bracts, leaves, and stems are densely covered in silvery hairs giving the plant a silver, white appearance. Fruits are a one-seeded pod measuring less than 1/4 " in length.
