This is nursery that specializes in plants native to Iowa, particularly Iowa prairies. They have an impressive variety of plants native to the upper Midwest. By the way they will ship to you, and in fact do most of their business via online and mail. I discovered the Ion Exchange in college(I majored in natural resource management at Iowa State University), through professors that have used them to get plants and seeds for their restoration and research projects. They can get large amounts of seeds for large project, like a CRP planting, or enough for the small garden in your yard. They even ship live plants. They employees are beyond nice, and very knowledgable.
