This Vernonia gigantea is just now beginning to flower, you can see most of the flowering buds here are still unopened. Picture taken July 24, 2009.
The common name for Vernonia is ironweed. In the Hoosier way of saying things, that comes out more like "arnweed".
Ironweed adds a familiar bit of purple color to old fields all over Indiana between now and autumn.
This is just north of the Purdue football stadium. The land is marked as a wildflower garden, it seems most of what is here is big bluestem grass (Andropogon gerardii) and rosinweed (Silphium integrifolium).
