Halgrimson: Herb gardens my cup of tea

When I had the idea to do a series of columns on various herb gardens, I called my friends Eric and Joe Bergeson at their third-generation nursery in Fertile, Minn. Eric gave me the name of Mara Trygstad, a Fargo woman who was planning to open an herb nursery, and Joe gave me a Web site to check out: www.johnnyseeds.com.
