Nathan Corymb – Vegetable Seed-Saving as a Business Enterprise

By Practical Farmers of Iowa

Nathan Corymb’s seed-saving passion led them through Seed Savers Exchange, Sativa Biodynamic Seed (Switzerland), Bingenheim Biodynamic Seed (Germany) and Turtle Tree Biodynamic Seed – which they founded in New York state. During this session, he discusses what plant-family characteristics should be considered; why population size and isolation are necessary to maintain true-to-type open-pollinated varieties; and how seed-growing can complement CSA, market or processing enterprises.

Nathan Corymb owns Meadowlark Hearth Biodynamic Seed Initiative ( with his wife Beth near Scottsbluff, Nebraska. The land is certified organic and Demeter Certified Biodynamic. The Corymbs raise vegetable seed, and operate a year-round vegetable CSA, and a micro grass-fed and grass-finished dairy on 500 acres.
