History

Silverthorn Ranch is a fourth generation nursery started in 1967 by Frank and Thelma Loomis. The nursery, originally named Frank and Thelma’s Diggin’s, was first located in Baldwin Park, California.

In 1967, the nursery was relocated to Fallbrook, California and renamed Silverthorn Ranch.

Frank and Thelma retired later that year and their two sons entered the business. Both Paul and Jerry were successful in their own ways. Paul was a project manager for a large construction company, Swinerton and Walberg. Jerry owned and operated Loomis Box Company, which manufactured and sold wooden nursery flats to the nursery industry. Over the years they developed diverse new markets to sell their plants. Many good ideas came and went over the years, but their constant attention to a changing market kept their business strong.

In 1997, Paul retired from Silverthorn Ranch. With an opening in the family business, Jerry’s son, Wayne, came to work. Wayne had recently graduated from college and was already working for a nursery in Clovis, California. It was here that he gained a background in propagation, nursery production, chemical application, and sales.
