A Long Production History

eed production is an important industry. Willamette Valley growers have many years of experience and understand the production of quality seed for world markets.

Quality seed production in the Willamette Valley began at the turn of the century and increased rapidly as the world's transportation network improved. Vegetable and specialty seed production dates back to the 1930's. Since then, all temperate season crops have been grown, including Brassicas, Radish, Squash, Pumpkins, and many others.
