^a Seeds were collected from multiple remnants.

^b Seeds were collected from one remnant prairie within the native habitat for each ecotype (e.g., DRY ecotype in Hays, KS, USA, 38°51′13.2″ N, 99°19′08.6″ W; MESIC ecotype in Manhattan, KS, USA, 39°08′22.3″ N, 96°38′23.3″ W; and WET ecotype in Carbondale, IL, USA, 37°41′47.0″ N, 89°14′19.2″ W).

^c Seeds purchased from Ion Exchange Inc. Harpers Ferry, IA, USA.

^d Dalea purpurea was initially sown for the experiment but was absent in field surveys from 2012 to 2019.
