Daniel Reed

Often seen in meadows and fallow fields the rich purple of the flowers and the tall straight stems make this plant easy to spot. According to my father the stems can be used for kite building.

Medical Uses: Some spices of Ironweed have been used to treat stomach problems. Native Americans may have used the root to treat post childbirth pain and to restore regular menses.(Foster & Duke)

Similar Species: New York Ironweed, V. noveboracensis is not as tall and has between 30 and 50 flowers per head. The bracts end in long bristles.
V. glauca is much shorter, usually under a meter, and has broader leaves. It is usually found in well drained open woods or fence rows.
V. flaccidifolia is a rare species of Ironweed. It has less than 30 flowers per head and is found in a relativity limited area more or less centered where Tennessee, Alabama and Georgia meet.

One of the best general guides to wildflowers of the North Eastern and North Central United States. Newcomb's key is an excellent, simple method for identifying plants. Newcomb has drawings for almost every plant mentioned that are excellent aids to identifying the species. Though only the more common plants are covered this is often the first book I pick up when trying to identify a wildflower.
