Orange Day Lily (Hemerocallis fulva)

Blooms: Summer months, flower blooms last only one day - namesake. Not a true lily but has similarly shaped flowers.

Originally from Asia, this plant has escaped cultivation and become a nuisance across the US creating hardy patches through wandering tuberous root systems. 

All parts of this plant are edible: Leaves and shoots can be eaten when very young, raw or cooked (they become too fibrous when aged), flowers and young tubers can also be eaten raw or cooked, flowers may be dried and used as a thickener in soup.

In Louis Bromfield’s book Pleasant Valley, he talks about Johnny Appleseed’s time in the area; one of the stories tells about anytime Johnny would call on a neighbor he’d bring the wife a bouquet of these orange flowers, the seeds falling from his bag wherever he roamed, and as Johnny wandered (and he saw a good many states) the flowers followed him.
Highly unlikely there’s much truth to the story but it’s a good tale nonetheless.
