Abstract
Purple milkvetch occurs in a variety of grassland, shrubland, and forest vegetation types. It is often associated with depressional or poorly drained areas where water collects or persists at least early in the growing season (Barr 2015). Throughout its range, it is found in partially moist, shady sites (Hermann 1966) such as meadows, water edges, and cool, brushy slopes (Barneby 1989; Spellenberg 2001; Fox et al. 2010). It is considered infrequent to locally common in prairies, meadows, thickets, open woodlands, and along roadsides and lake and stream margins (Stubbendieck and Milby 2021).
