While many of these beautiful plants existed prior to burning and clearing, their numbers increased dramatically after restoration work. In spring, they spread over the landscape of the prairie, covering the entire area with a blanket of blue. Once they've finished blooming, the plants produce egg shaped seedpods with a thin, green shell which turns black as it dries out. A tiny bore that feeds on the Indigo seeds, chews a hole through the shell and eats the seeds within. Seeds are harvested annually in an attempt to save as many as possible before the bore gets to them.
