Wild flowers are classified into two general types: prairie and woodlands. They appear in every state.
Choose flowers with long stems for a wild flower bouquet. Prairie wildflowers include brown-eyed Susan and Echinacea; both are suitable for cut flowers. The flowers should stay open without direct sunlight. If they close on cloudy days or at night, they'll close inside.
Many wildflowers are protected and should not be picked for bouquets or for transplanting, according to the University of Minnesota. Check with your local university agricultural extension to find out what species are protected in your area.
Wildflowers may be annuals, biennials or perennials.
