The International Herb Association was founded by Mary Peddie (1921-2002) of Washington, Kentucky. The association was originally named the International Herb Growers and Marketing Association, IHGMA. Many famous people in the world of herbs have been members, among them Adelma Simmons and Ron Zimmerman, now of The Herbfarm restaurant in Woodinville, Washington.
